2d drawings

[MomoJawad]

Hei,

Iam trying to create 2d views for bridges using sporph and others components (manual code), and then exploding breps and retrieving edge segments.

I have this model:

My drawing:

My aim is to differentiate between visible and hidden edges so that i give hidden edges a dashed line-type. So i need kind of function where to check if there is any brep faces between the camera (Point/plane) and the edge segment then assign whether its hidden or not.

Any smart way to implement that?

There is a viewport mode that can do that.
Technical Ultra.
Find it under this thread.

Thanks for your reply. i downloaded ulta viewport and its working. But the problem is that we need the geometries to be in 2D not 3D since we need export them into dwg autocad also.
