I have modelled a bridge.
Create a vertical clipping plane along the long axis of the bridge.
Create cplane coincident to the clipping plane.
Run make2d and have clipping plane intersections ticked.
Group output ticked.
Observations:
-Intersection curves are terrible unclosed and cant be hatched
-Run simple twosetintersection bridge vs clipping plane and see how much better the resulting curves are compared to make2d
Expected behaviour:
-Make2d should create nice closed curves like in case of intersectiontwosets
-curves behind clipping plane obscured by the solid should be “hidden” model.3dm (1.5 MB)
You should create a view with vertical clipping plane in the central axis of the bridge and filter only clipping plane intersection curves coming from make2d
I do not get messy curves as far as I can see- I guess you should make the bad thing happen, then save and post the file so I can see what I am looking for.
