Is there any way to use an existing 2D CAD elevation and make it 3D (push/pull it essentially) without having to completely redraw it? I’m trying to create this accordion style sliding door. The architect already drew it so it doesn’t make sense to me to redraw it but when I try to push/pull the faces, it looks fine from the front but it’s not solid on the opposite side. I’ve attached the 2D drawing below
That is expected behavour When push-pulling a face with geometry connected..
It is explained here:
In general practice:
• Don’t use the imported lines to create faces from.
• Do group all those lines (so nothing you draw will “glue” with it), and then,
• Use native tools like the rectangle tool to draw each part from scratch while snapping to and tracing over the imported reference.
• When finished, hide or delete the imported reference.
Just making faces with the imported lines doesn’t give you stuff that’s organized the way it needs to be organized in a SketchUp model. All raw geometry should end up as part of a group or component, and each of those groups/components should be a logical “thing” or gestalt like “door leaf”, “door frame”, “glass pane”, etc. Make each part logically one by one using duplicate and mirror as needed to model efficiently.
One final reason is that past experience has suggested that imported CAD linework seems to sometimes break after some editing in SU, leaving quite a mess to clean up later.
