Arch Workbench - Parametric Window placement

Postby vondav » Thu Jun 03, 2021 10:30 pm

A few weeks ago I tried parametric window placement in Arch Workbench and found how to do it. And finally I made a short video about it.

There are some problems with the proposed workflow. For one thing you are attaching a sketch to the face of the wall. This is not a good idea.
See:
Feature_editing
Topological_naming_problem

Also:
Using attachments you can place the base sketch of the window in relation to the base sketch of the wall. This would be more stable and efficient.

You are right, my mistake (I'm usually using RealThunder Assembly3)

Using attachments you can place the base sketch of the window in relation to the base sketch of the wall. This would be more stable and efficient.
Could You show me details, how can it be done, please?

There is still an issue with the normal of the window. The default (0,0,0) results in an inverted extrusion.

How about this workflow?
  • First make a new document and name it Layout_master.
  • Then make a Part.
  • Then create a master sketch on Parts XY-plane.
  • Then make planes passing through each centerline representing a wall center. Save and close document.
  • Create a new document and make a Part in it. Name the document Wall_North.fcstd. Link Layout_master into this new document. Create holes for windows using the previously created center planes as attachments.
  • Repeat for all walls.
  • Use your favorite Assembly workbench and put all together, and Bob's your uncle!

Thanks, but this solution has problem that hole in the wall will not move if you change window position?

You have to recompute the wall.

OK, it helps
