Important

  • If you have any doubt, ASK, DON’T ASSUME
  • Working with BIM has to be systematic, especially once we do Tender Drawings and GFC Drawings
  • Follow office protocols to save your time as well as your colleagues’ time
  • The software saves time only if you give due diligence to how you use it and the protocols you follow

1. Basics

The Basics

1.1 Opening a solo file

  1. To open a Solo File, press Ctrl+O and select the file from regular server

1.2 Opening a teamwork file

  1. To open a Teamwork File, press Ctrl+Shift+O and select the team work file.
  2. Check if the teamwork is connected + if you are logged in with your username
  3. Ensure the BIM Server system (BV DOSHI) is switched on

1.3 BIM cloud library

  • Mostly Libraries will be preconnected in the template
  • If that is not the case - you can connect to the BIM cloud library
  • Connect to Offline Library only if there is a problem with the BIMcloud Library
  • Offline library location \\FLWRIGHT\e\03_SOFTWARE & TUTORIALS\05_ARCHICAD\ARCHICAD 28\02-LIBRARY
  • Adding / Removing a Library File can be done from Files>>Libraries and Objects>>Library Manager

1.4 Work Environment

  • Work Environment Profile determines interface, arrangement of toolboxes, shortcuts etc.
  • For ease of use - we have a pre-determined work-environment.
  • To access Work Environment dialog box Options>>Work Environment >>
  • Offline Work Environment Profile setting location \\FLWRIGHT\e\03_SOFTWARE & TUTORIALS\05_ARCHICAD\ARCHICAD 28\03-WORK ENVIRONMENT
  • Select “AC28 Work Environment_APC”

1.5 Project Info & Location

  • Update Project Info such as Project No., Project Name, Project Status, and Client Details
  • Update Project Location Co-ordinates, Timezone, and North Point
  • Click ‘Set Project North’ to graphically orient North Point. (Take North Point from topo survey or Google Earth)

2. Modelling in Archicad

The Components

2.1 Layers

  • Model elements in their proper layers - description of each layer is self-evident.
  • Layer Combinations - it is preset for each drawing type (like plans, sections etc.) and for each project stage.
  • Create new layer combination or update existing layer combination. Do not use custom settings
  • Annotative items such as dimensions, labels, and 2D drafting should be in their respective layers.

2.2 Story Settings

  • Establishes the project floor levels - First thing to do in any project
  • Create Stories below the project story for Favourites and Modules
  • Give placeholder stories for new Modules
  • Project Zero will be the same as Ground Floor level
  • All story levels will be FFL - Finished Levels. Accordingly leave offset for finishes when modelling structural elements

2.3 Home Story

  • Always ensure that every 3D element is linked to a homestory
  • If you have to copy elements from one floor to the next, do so from the floorplan. Do not copy and drag elements vertically in 3D window as it’ll not be linked to the respective home story.
  • For full walls, columns, etc., ensure Top Link as the next corresponding story - Home+1 or Home+2 etc. This way, if the height of floors change in the project, all heights of walls etc., will be automatically adjusted.
  • For short walls, you can keep the Top Link as ‘unlinked’ and type in the exact height of the wall
  • Following the logic shown in the next scheme is important because it determines how the elements will show in floorplans and other drawings

2.4 Favourites

  • Create Favourites for all elements (mainly structural elements) before starting the model.
  • Ensure all settings such as Element ID, Material, Finishes, Load Bearing Status, Location (Interior / Exterior), etc. are saved with the favorite
  • You can model all favourites in a separate story (below the main model)

View options

2.5 Model View Options (MVO)

  • MVO determine the Level Of Detail (LOD) to be shown in the model
  • It shows how openings, structural elements, zones, etc. are shown and in what detail
  • In our template, we determine the MVO based on project stages - Site, SD, DD, GFC, WEB
  • More details on functionality from the online Archicad Help

Model View Options: Archicad Help

2.6 Graphic Overrides

  • Graphic Overrides help change the appearance of elements in drawings and model
  • We can get multiple drawing types by overriding the graphics (appearance) of the drawings or model
  • In our template there are preset graphic override templates for drawing type and phase of drawing.
  • The overrides can be changed based on rules and the hierarchy of those rules

Graphic Overrides: Archicad Help

2.7 Renovation Status

  • To keep track of what is the existing structure, to be demolished, and new
  • Site, surroundings (building, trees, pavements etc.), existing trees, etc., should be in existing layer
  • New construction (our design) should be in New.
  • Any building / structure to be demolished should be in the ‘To Be Demolished’ status

Renovation Status: Archicad Help

Model Position

2.8 Origin Point

  • Start the model on the Margin - indicated with the label
  • Ideally, place the corner grid intersection
  • If hotlinks are from a separate file, ensure the origin and story settings are the same as the base model

2.9 Organiser

  • Create worksheets, drawings, sections etc. with the naming as suggested in the template file
  • Add drawings in the viewmap under the respective folders. eg. 100 - Floorplans, 200-Sections etc. Check example project - ANJAC SF Block - to get an idea
  • Always add drawings to Layout only from the Viewmap and not from the project map
Project Map
Raw drawings, views and documents
View Map
drawings, 3D, documents applied through a specific combination of ‘Layers, Graphic Overrides, Renovation Status, Scale, Model View Option, etc.’
  • It is possible to generate multiple drawing quality from the settings saved in the Viewmap
Layouts
Compile the drawings saved in the Viewmap into layouts (almost all default are set)
Publisher
Layouts can be published in various formats including 3D, DWG, JPEG etc.

Always add drawings to layout in the following way

  1. Project Map
  2. View Map
  3. Layout

Never add drawings from Project Map directly to Layouts

Important

  • Never add drawings directly into layout from Project Map
  • Always add to View Map in the respective folders and then to layout
  • Layouts to be in respective folders

Always add layouts as a shortcut to the publisher set. This way, the publisher set remains up-to-date with new layouts as well. You can create a shortcut for PDF and another for DWG.

Elements & Element ID

  • After Design Development (DD) Stage, and when making Construction Drawings (CD) every element should have an element ID.
  • Element ID is used to identify and filter elements and very important for Quantity Take-off (for preparing BOQ)
  • Through codes and text, we’ll evolve at element IDs

Element ID per Element Type:

2.10 RCC elements

  • Includes RCC slabs, columns, beams.
  • Use the structural element number as element ID

Naming will be as follows

ElementElement ID
SlabsS1, S2, S3,….
ColumnsC1, C2, C3,….
FootingsF1, F2, F3,…
Roof beamsR1, R2, R3,…
Lintel beamsL1, L2, L3,…
Plinth beamsP1, P2, P3,…
Grade beamsG1, G2, G3,…

Important

  • For structural elements (even simple, monolithic elements) always make the profile as a composite (for slabs) and complex profiles (for columns & beams)
  • Name the complex profile with the Element ID followed by size.

eg. Profile of Column C1 of 300x450mm will be named as _C1-300x450

2.11 Walls

  • All wall types
  • For exterior walls, use the layers starting with the layer code 21 and for interior walls, use layers under code 22
  • Each code as 2 sub-layers: load-bearing, & non-load bearing. Use accordingly
  • Element ID will contain the material and thickness as follows.

For example for a conventional brick wall of 230mm thickness it would be:

BRMaterial code
-Hyphen (no space)
230Thickness

Following are the material codes for various wall materials

MaterialCode
Conventional BrickBR
Flyash BrickF.BR
AAC BlocksAAC
Concrete blocksC.BR
Some examplesElement ID
Flyash brick 230mmF.BR-230
AAC blocks 100mmAAC-100

Note

  • ‘_E’ at the end of the element ID denotes that it is an exposed wall
  • For example BR-230_E denotes Conventional brick, 230mm wide and exposed
  • Use the element IDs properly as it’ll be useful with quantity takeoff and BOQ

2.12 PCC

  • PCC layer will be modeled separately in the model depending on its location.
  • PCC elements will be named as similar to other elements
  • For eg., PCC-100, PCC-200 etc. These denote the thickness of the PCC

2.13 Finishes

  • Finishes come in 5 types:
Finishes locationLayerDescriptions
External wall41-External wall finishesIncludes cladding, and cladding elements, sill & coping finishes
Internal wall42-Internal wall finishesIncludes temporary partitions, cladding, sill tops, etc.
Floor43-Floor finishesIncludes screed and final flooring finish such as tiles, granite etc.,
Ceiling45-Ceiling finishesFalse ceiling
Roof47-Roof finishesFinishes on external roofs, terraces - mostly weathering course

Element ID for the finishes (wall, floor, or ceiling) will follow the below format

LAYER CODE
-
MATERIALMaterial + type especially for stone. eg. STONE.SG (Stone-Steel Grey). This can be filled in detail if we know it. Else just mention material
-
THICKNESS
_
FINISH TYPE/LOCATIONThis is optional and depends on the material. For stone, you can fill the finish type: G-Glossy, R-Rough, L-Lapatro, F-Flamed, A-Antique

Examples

Element IDMeaning
Wall finishes
41-STONE-20_G20mm External Stone cladding with glossy polish
Floor finishes
43-TILE-1200x600Vitrified tiles of size 1200mmx600mm in Hall area
43-STONE-KOTA-20_AKota stone, 20mm thick, Antique finish
Ceiling finishes
45-VNRFalse ceiling with veneer (on plywood backing)

Since we may not know the finishing material at the start of the project, we can fill in the details as per different stages.

Eg: At the Design Development (DD) stage, the details can be fewer compared to the Construction Documents (CD) stage.

43-TILE-1200x600_G

43-TILE This level of detail is enough for upto DD stage
Complete details can be added at the subsequent stages

Material codes
TILEvitrified tiles
GYPMgypsum boards
STONEnatural stone
VNRveneer
CEMENTcement flooring
SCRDscreed filling
Stone finishes code
GGlossy finish
RRough finish
AAntique finish
FFlamed finish
LLapatro finish

Rest can be evolved as per individual projects

Note

  • If you use a code for a particular material/element, ensure that the same code is used for all the similar materials/elements
  • This is important to calculate all the same materials as one quantity for the BOQ.

Modelling elements

  • Model each element separately. This is important so that Quantity calculation and drawing documentation becomes accurate.
  • We model in the following order (eg. is for framed structures):
  1. Structure
  2. Infills and openings (walls & cutouts)
  3. Articulation
  4. Finishes

Step 1 Model the Structure

All elements to be made individual without overlapping with each other

Step 2 Model the infill

Walls (even if made of single material) must be created as Composites

Step 3 Add lintels, windows etc.

Add windows, doors, lintel beams, sunshades etc. Lintel beams and their bearings can be embedded in the wall itself

Step 4 Add finishes

Add all finishes in their respective layers and also as composites

Note

  • We model all elements separately so that we can get accurate material quantities
  • Ensure all elements are modelled accurately and are orthogonal etc., snap points touch each other

3. Documentation

Model Views

3.1 Model Views

  • The same 3D model can be used to extract information and create drawings for various project stages SD, DD, CD, Presentation etc.,
  • The View Settings can be used to show/hide/modify information on the drawings based on specific requirements

This is the view setting dialogue box where the visualisation and level of details are predetermined.

Note

  • Ensure that all views have a View Map placed within their respective folders eg. 100s=Building Floorplans, 200s=Sections etc. (see chapter 2.9)
  • Move drawing to layouts only after creating the appropriate View Settings. Only Model Views can be sent to the folder.
  1. Project Map
  2. View Map
  3. Layout set
  4. Publisher (Final Drawing)

Drawings

3.2 Drawings and Scales

  • All drawings that you generate from the model and which we print or make a PDF of.
  • Drawings with details corresponding to the stage of the project - SD, DD, TD, or CD
  • We have a certain scale standards for the drawings
MetricFeet and InchesDomain (Architecture / Interior)Drawing Purpose
1:2001/16” = 1’ (1/16 in 1)ARCH onlySite plans
1:1501/12” = 1’ (1/12 in 1)ARCH onlyBuilding floorplans, sections & elevations (special cases only)
1:1001/8” = 1’ (1/8 in 1)ARCH onlyBuilding floorplans, and respective sections & elevations
1:751/6” = 1’ (1/6 in 1)ARCH onlyBuilding fragments
1:501/4” = 1’ (1/4 in 1)ARCH onlyBuilding fragments such as staircase drawings, wall sections, toilet details etc.
1:201/2” = 1’ (1/2 in 1)ARCHDetails such as joinery drawings, railing drawings etc.
INTAll interior drawings including layout, elevation without shutters, shutter layout, false ceiling drawing etc.
1:101” = 1’ (1 in 1)ARCHDetails such as joinery drawings, railing drawings etc.
INTAll interior drawings including layout, elevation without shutters, shutter layout, false ceiling drawing etc.
1:53” = 1’ (3 in 1)ARCHDetails such as joinery detail, railing detail, any fixing detail, gutter detail, etc.
INTInterior details zoom-in

3.3 Plans

  • All floorplans can be taken directly from the 3D model
  • Draft 2D information such as dimensions, annotations etc., in the respective 2D layers w.r.t. to scale. For Eg. for Floorplans,
    • Dimensions in layer ‘Dimensions, General’
    • Annotations in layer ‘Text, General’
    • Any element drafted in 2D such as hidden lines etc., in layer ‘Info-General’
  • Set View settings as per drawing output
  • Dimensions should be linked to the wall elements so that they change automatically when sizes change
  • Floor level tags should be connected to the finished floor level
  • Door/Window tags to be linked to the openings

3.4 Sections & Elevations

  • For Sections and Elevations it is not easy to have all details from the 3D Model itself
  • We do a 2-way approach. 3D model for the base + Worksheet for all 2D-data
+

The Linked Section (from the 3D Model) and the Worksheet are overlaid one over the other in the layout to get the final output

3.5 Fragments

  • We follow a 3D (linked section/elevation) + 2D (worksheet) approach also for the fragments

Note

If you need any clarification open a reference project to understand how it is done.

Reference Project: ANJAC East Block Extension (or) ANJAC SF Block, Phase 1

3.6 Details

  • We follow a hybrid method for Details
  • The source drawing for the detail will be directly drawn from the 3D model. The actual detail will be done as a 2D copy next to the 3D generated detail
  • Why this method? The detail connected to the 3D model will change every time we Rebuild Model or change something. This will affect the completed detail if we change something in the last moment, even temporarily.
  • We’ll use Source Detail Markers for generating the detail and a Linked Detail Marker in any other drawing where the detail is repeated. This way, we can have the marker repeat in several drawings while linking to the same detail

Schema for Details workflow that we follow:

Step 1 Detail Markers

There are 2 types of Markers saved in Favourites

  • Source Markers: They are drawn directly in the Section / Plan of the 3D model. They generate the Detail. This will be hidden in layer settings and when printing
  • Linked Marker: These are markers that can be linked to the source marker and opens the linked detail. This will be used in any of the drawings where we want to show the detail marker. As a linked marker, its naming will be that of the source marker.
Step 2 Draw Source Marker
  • Open main Section/Plan (connected to 3D) where the area needs to be detailed
  • Select _Detail Source Marker from the Favourites
  • Draw a rectangle around the area where the detail needs to be generated.
  • Tip: Usually draw the rectangle to A3 size (4200x2970mm) so that all details are of similar sizes
  • Detail ID and Detail Naming Conventions:
    • Details in Section (Vertical) will be named with a Prefix V. (eg. V.01, V.02, ...)
    • Details in Plan (Horizontal) will be named with a Prefix H. (eg. H.01, H.02,...)
Step 3 Generated Detail & Copy
  • The detail generated is shown as 2D lines and fills. But if anything in the model changes, and we ‘Rebuild the Detail’ it reverts back to what is there in the model
  • We therefore copy and move the generated detail and change fill type, add 2D elements, dimensions, annotations, etc., to create the final detail
  • Use ‘Building Material Cut Fill’ wherever possible.
Step 4 Use Linked Marker in the relevant drawings
  • Use Linked Marker from Favourites in the relevant drawing set - in the worksheet along with other annotations
  • Link the Linked Marker to the relevant Source Marker. It’ll copy the Detail ID and Name from the Source Marker
  • Linked Marker will be a Circle or an Ellipse to indicate the position of the detail

Annotation

3.7 Automatic Texts

  • Many text fragments would be repeated in multiple drawings. You need not have to type them repeatedly.
  • You can setup automatic texts for projects that are pre-filled.
  • Changing the mastertext will change the text block in all drawings where that occurs
  • Certain texts that are similar across projects can be taken from other projects (check with project architect)

To know how to insert Autotext in a drawing: Autotext: Archicad Help

To access Autotext blocks: FILE >> INFO >> PROJECT INFO (Opens all the Autotext blocks)

4. Layouting

4.1 Layout Book & Master Layouts

  • A Layout Book contains all the layouts in the project
  • A default book is already created in the template.
  • Relevant folders for floorplans, sections, & other drawing types are pre-created
  • Master Layouts are the sheet templates. Any changes to it will change the template in all layouts where the particular Master Layout is used.

Note

  • Always add drawings to the Layout only from the View Map
  • If you add directly from the Project Map, multiple individual views will automatically be created which will make the whole project a mess
  • Ensure none of the View Setting is set to custom (esp. the Layer Settings) if done like that, it means you haven’t modelled systematically, and you’ll spend hours correcting layouts when changes happen

4.2 Layout info

  • Populating info in layout such as Date, Drawing name etc.
  • Repeated information such as keyplans, door/window schedules, material hatch legend etc., can be added to the Master Layouts.

4.3 Adding drawings to layout

  • Add from Saved Views only
  • Ensure All View Settings (scale, layer settings, graphic overrides etc.,) are correct and not set to custom
  • Drag and drop into layout
  • Adjust the layout window
  • Drawing title can be adjusted in the Drawing Settings (click drawing and then Ctrl+T)

5. Publishing

5.1 Creating a Publisher Set

  • You can create multiple Publisher Sets.
  • This way, you can maintain Publisher Sets for various Drawing Stages (such as SD, DD, etc.), various formats (like BIMx)
  • Publisher Sets can be accessed from Organiser Window

5.2 Adding Layouts to Publisher set

  • It’s better to clone the layout book directly into the specified Publisher Set by creating a shortcut
  • This way, any new layout added/changed will automatically be added to the publisher set
  • It can be done from the Organiser tab
  • The cloned layout book can be given different formats such as PDF, DWG etc.

Note

  • For DWG format, you need to select the relevant Translator.
  • In our office, we have predefined translators based on scale and output
  • Any project specific changes, ask a project architect for help

More info: DWG/DXF Translator Settings: Archicad Help

5.3 Saving the drawings

  • Right Click the publisher set to open ‘Publisher Set Properties’
  • Check ‘Create a real folder structure’ - This will recreate the same folder structure similar to how you’ve organised all the layouts in the Archicad file
  • Browse and select the destination path.

6. Schedules & Quantity Take-off

Schedules

6.1 Types of Schedules

  • Schedules are automatic lists extracted from the information in the model
  • There are 3 types of schedules
Element Schedule
Used to generate list of independent elements such as doors, windows, furniture lists etc.
Component Schedule
Used to list information about each component of composite, profile or basic elements: walls, slabs, roofs, morphs, meshes, and/or multi-component profile elements. We use it to take material quantities
Surface Schedule
Used to generate list elements by their exposed surfaces.
  • In our workflow we use pre-built schedules for certain things

Interactive Schedules: Archicad Help

6.2 Area Schedule

  • Area schedule is derived from zones.
  • It can be split based on zone category, layers, home story etc.,
  • You can change based on the scheme settings

6.3 Door / Window Schedule

  • Doors and windows can be done as a schedule with elevations & plans
  • Dimensions and text can be annotated directly onto the schedule
  • Any change to the Door/Window in the model will automatically be updated here

Pro tip

  • You can select any of the Element (Door/window etc.) and use the feature on the Top Left of the schedule to select it directly in the 3D Model
The two buttons at the top left of a schedule window used to select the element directly in the 3D model.

6.4 Component Schedule

  • Used to split composite elements as separate components (For eg. a composite wall into its separate components based on different materials)
  • We use it to calculate the material quantities for each element

Important

  • It is important to follow proper Layers, Element IDs, Complex Profile Namings, etc., as shown in Chapter 2 of this module
  • If it is not followed, quantities will not be right and model editing with verification will be a time consuming and tedious process
