How to generate parametric geometry in Discovery using scripting?

Erik Kostson

Is it possible to generate parametric geometry in Discovery using scripting, and is there an example?

Erik Kostson

Yes it is.

Below is a simple example of a cylindrical shell with radius = Rad (parameter), and height = Hei (parameter).

First open the script editor inside Discovery, and activate Embed Script (slide nr 10 / step1: see link below). After that we get the parameter icon (slide nr 10 / step 3).

As shown in the above link, define the 2 parameters needed for the below script (Rad, and Hei).

In the script editor paste the below script, and run it in order to generate the geometry:

r=Parameters.Rad
h=Parameters.Hei
sectionPlane = Plane.PlaneXY
result = ViewHelper.SetSketchPlane(sectionPlane, None)
origin = Point2D.Create(M(0), M(0))
results = SketchCircle.Create(origin, M(r))
mode = InteractionMode.Section
result = ViewHelper.SetViewMode(mode, None)
selection = Selection.Create(GetRootPart().DatumPlanes[0].Curves[0])
options = ExtrudeEdgeOptions()
result3 = ExtrudeEdges.Execute(selection,M(h), options)
GetRootPart().DatumPlanes[0].Delete()

mode = InteractionMode.Solid
result = ViewHelper.SetViewMode(mode, None)

selected_body =  Selection.Create(GetRootPart().Bodies[0])
secondarySelection = Selection.Empty()


# Create a new named selection group with the selected faces

result = NamedSelection.Create(selected_body, secondarySelection, "Mysel")
