Creation of a Roof Face

[as_named]

Hi

 

I need to create a Roof Face. It should have rectangular shape with predefined thickness. Here is my code:

vs.BeginRoof(roofAxisPoint0[0], roofAxisPoint0[1], roofAxisPoint1[0], roofAxisPoint1[1], upslopePoint[0], upslopePoint[1], rise, run, 1, 0)
vs.Rect(rectTopLeft[0], rectTopLeft[1], rectBottomRight[0], rectBottomRight[1])
vs.EndGroup()

roofFace = vs.LNewObj()
vs.SetObjectVariableReal(roofFace, 170, roofFaceThickness)
vs.SetFPat(roofFace, 1)

It works and required object is being created. But if I use the 'Clip Tool' (Shift + N) on resulting object then its mesh become ruined (missing faces and edges). I checked it by exporting the object as OBJ and opening in other software. If I set fill style or fill color the mesh become fixed again (same way to check - export to OBJ). Same effect may be achieved by using vs.ClipSurface() function.

 

There is an original tool (AEC/Roof Face...). It works without mentioned issue. I tried to compare created roof faces (my tool and the original): Export/Export Script... and compare {Object Creation Code} sections. First parts are identical but the original tool creates more entities. I don't understand why and I couldn't re-use it in my code properly.

 

So my question is: how to properly create Roof Face objects?

 

I use Vectorworks 2019.

Confirming this happens to me as well.

A workaround is to apply a roof style to the created roof.  

 

vs.BeginRoof(roofAxisPoint0[0], roofAxisPoint0[1], roofAxisPoint1[0], roofAxisPoint1[1], upslopePoint[0], upslopePoint[1], rise, run, 1, 0)
vs.Rect(rectTopLeft[0], rectTopLeft[1], rectBottomRight[0], rectBottomRight[1])
vs.EndGroup()

roofFace = vs.LNewObj()
vs.SetObjectVariableReal(roofFace, 170, roofFaceThickness)
# vs.SetFPat(roofFace, 1)

style='' # import/create a roof style and add to this variable
vs.SetRoofStyle(roofFace, vs.Name2Index(style))
vs.ResetObject(roofFace)
