How to Parametrizing an Angle in BricsCAD

Hello everyone,

I am currently in the process of transitioning some workflows in our CAD library from dynamic ACAD blocks to parametric BricsCAD blocks while also adding new features. However, I’ve encountered a major challenge when trying to parametrize an angle.

A simple example: I want to parametrize a 3D solid beam.

  • The material cross-section should be selectable via a design table.
  • The length should be adjustable via a user parameter.

So far, so good. Now, I also want to be able to angle the ends of the beam and parametrize this property. The goal is to control the following aspects via parameters:

  • Cross-section
  • Length
  • Miter angle at one end
  • Miter angle at the other end

I have spent several hours experimenting with parametrization, especially using the Angle Constrain, but I can’t get a proper output. Either nothing happens, or the part gets completely deformed.

Does anyone have experience with this? Is there a reasonable approach to parametrically controlling the angles of the beam ends, or is this not really intended in BricsCAD?

Thanks in advance for your help!

    Hello.

    The geometric kernel, ACIS, has some limitations when it comes to parametrizing a 3D model.
    So, some things might not work.

    For this case, the attached model could be used as a start point.
    The safest approach would be to use it as a block, inserted into another drawing.
