Sculpt - cannot get surfaces right

[NachoShaw]

Hey

im trying to make a sculpt feature but i keep getting an error on the CreateSculptSurface function.

I am creating a surface of a curved lump by using the thicken command as a surface with a 0 thickness. This gives me

ThickenSrf in the browser

srf1 in the surface folder

I am creating an ObjectCollection to place the surface in and have tried many options like

adding srf1 to the collection

looping the faces and adding them individually

but when i get to the point of creating the SculptSurface, i get an error

Are there any examples of this working properly within a part component environment? In total, there are 6 surfaces to my thicken feature. None of them are planar or can have a plane attached to them.

Question:

can i convert a non planar face / surface to a work surface? If so, how? is that also a loop through faces?

the api help file is quite limited to examples.

one thing i do know is that when i do it manually, if i select the ThickenSrf, that is shown as the underlying surface and if i select srf, that is show too with ThickenSrf underlying that.

Thanks

It's a bit hard to help without any reference to the code you are using, but with a watertight WorkSurface this bit of code has worked for me:

Dim pDef As PartComponentDefinition = TryCast(ThisApplication.ActiveDocument.ComponentDefinition, PartComponentDefinition)
If IsNothing(pDef) Then Logger.Trace("Not run in a Part Document") : Exit Sub
If pDef.WorkSurfaces.Count < 1 Then Logger.Trace("No work surface to sculpt") : Exit Sub

Dim SurfCol As ObjectCollection = ThisApplication.TransientObjects.CreateObjectCollection
Dim NewSculptSurf As SculptSurface
'Create Sculpt Surface From Work Surface 1
NewSculptSurf = pDef.Features.SculptFeatures.CreateSculptSurface(pDef.WorkSurfaces.Item(1), PartFeatureExtentDirectionEnum.kSymmetricExtentDirection)
SurfCol.Add(NewSculptSurf)
'Create Scult Feature
Dim newSculpt As SculptFeature
newSculpt = pDef.Features.SculptFeatures.Add(SurfCol, PartFeatureOperationEnum.kNewBodyOperation)

More detail or a sample part of the problem would help.

Hey

Thanks for that. I'll make a sample part and post it later with a greater detail of what im trying to achieve.

Thanks
