How to Define a Reflected Ceiling Plan in BricsCAD BIM

Quick answer: A reflected ceiling plan shows a mirror image of the ceiling, useful for displaying the layout of lights and other ceiling installations. The Reflected ceiling option of BIMSECTION creates a section displaying the part of the building above the section boundary, confirming the same reflected ceiling section example referenced on this hub’s BIM sections page.

Creating a Reflected Ceiling Plan

1. Choose Reflected Ceiling Plan from the ribbon, or type BIMSECTION and choose R for Reflected ceiling. You’re prompted to select a point to place the section.
2. Select the ceiling, or a face parallel to its plane.
3. You’re prompted for a distance; either type a value in the dynamic dimension field to offset the section from its initial position, or left-click when the plane is where you want it.
4. The reflected ceiling section defines. View it by hovering over it and choosing Clip display from the Quad.
5. To generate the plan onto a sheet, hover over the section in the model and choose Generate Section from the Quad.
6. Click Open Model to open the resulting drawing; the sheet saves to the same folder as the model drawing.

For more on generating drawings from sections, see this hub’s separate article on that topic, and for adding tags and linear dimensions to annotate the result.

Frequently Asked Questions

What’s the point of a reflected ceiling plan specifically? It shows a mirror image of the ceiling, ideal for displaying the layout of lights and other ceiling installations clearly.

Can I select any face to define a reflected ceiling plan, or does it need to be the ceiling directly? Either works, select the ceiling itself, or any face with a plane parallel to it.

Where does a generated reflected ceiling plan sheet get saved? The same folder as the model drawing.

How do I view the reflected ceiling section once it’s defined? Hover over it and choose Clip display from the Quad.
