Overview: In BricsCAD BIM, it is possible to automatically generate 2D documentation as new .dwg files from a 3D model.
Lesson objectives: In this lesson, you will learn to:
- Generate 2D sections of your 3D model automatically as new drawing files.
- Open the generated files.
- Update existing sections.
- Work with section indicators.

BimSectionUpdate generates section drawings from BIM Section entities. The command can be used either by selecting a BIM Section entity in the 3D model or by selecting an existing section in a generated drawing. The result is placed in a new drawing, saved to the same folder as the model drawing unless a different folder is specified in the Destination File property of the BIM Section entity.
For more information about this command, visit the Command Reference article BimSectionUpdate.
Procedure: Generating BIM Sections.
BIM Sections can be generated in 2 ways:
- In the model space
- Using the BIM Project Browser
Select one or more BIM section entities.
(Optional) Edit the section properties (e.g. Scale, Name, Destination File).
Choose Generate section in the Model command tab of the Quad.
BricsCAD reports the number of generated sections and their name(s) in the Command Line e.g.:
8 section(s) were generated:
In the example above 2 plans, 4 elevations, and 2 cross-sections were generated and exported to 3 drawings.
In the Sections segment of the project browser, right-click the section.
(Optional) Choose 'Select Section Entity'. to change its properties in the properties panel.
Choose Update (1).
Choose Refresh in the project browser menu. (2).
A new section is generated in the Sheets segment of the Project Browser.
Open BIM sections
BimSectionOpen navigates between the model drawing containing a BIM Section entity and the corresponding generated drawing. The command works bi-directionally.
For more information about this command, visit the Command Reference article BimSectionOpen.
BIM Sections can be opened in different ways:
- From the 3D Model.
- Using the BIM Project Browser
To open a 2D document from the 3D model:
Select one or more BIM sections.
Choose Open Model in the Model command group of the Quad.
- The 2D section drawing(s) open(s).
To open the 2D section drawings from the Project Browser, do one of the following:
- Double click the sheet view in the Sheets segment of the Project Browser (3).
The 2D section drawing opens with the selected sheet view.
- In the Sections segment of the project browser, right-click the section and choose Display Section Result in the context menu
Update BIM Sections
BIM Sections can be updated in different ways:
- In the 3D model
- In the generated 2D documentation file
- In the BIM Project Browser
When the 2D documentation is no longer in sync with the 3D model, the corresponding sheet views display in red in the Sheets segment of the Project Browser.
Update BIM Sections in your 3D model
To update BIM Sections via your 3D model using the same process as used to generate views.
Update BIM Sections in the 2D documentation file
A red frame around the section result indicates that the BIM Section generated block is no longer in sync with the 3D model and needs to be updated. This can be done in Model Space or in the Layout.
Update a BIM section in Model Space
Place the cursor over the section block to update.
Choose Update Section in the Model command group in the Quad (4).
Update a BIM Section in a layout
Click the Layout tab.
Place the cursor over the viewport of the BIM Section to update.
Choose Update Section in the Model command group of the Quad (5).
The result of the previous section generation is stored on the dedicated BIM_SECTIONS_PREVIOUS layer. Thaw the layer (6) to check the modifications.
The content of the BIM_SECTIONS_PREVIOUS layer displays in magenta.
Update BIM Sections in the Project Browser
- Right-click on a section in the Project Browser.
- Select Update in the context menu.
A generated plan and reflected ceiling plan provide section indicators for interior elevations and detail sections if they intersect with the section plane.
The section indicators are stored on the dedicated BIM_SECTIONS layer. To change the visibility of indicators, turn the layer ON or OFF.
