Duplicate Along Path (without Conversion to Nurbs Object)

4 posts in this topic

Greetings and Happy New Year to you all,

 

Has anyone figured out how to duplicate an object (locus,symbol) along a 2D path, be it a polyline, polygon?

 

Developing a plugin to take a symbol object and have it duplicate along the Plugins 2D path (this being a 2D poly path plugin object type).

 

Have tried the :

def vs.GetPointAndParameterOnNurbsCurveAtGivenLength(inNurbCurve, inPercentOfLength):
    return (BOOLEAN, p, outParam, outIndex)

by converting the 2D path to a nurbs object, running the calc, then copying the /out/ data to the 2D path poly. However just realised the convert to Nurbs command takes into account the orientation of the view. This makes it not feasible for a path-pio object.

 

Any ideas?

 

Cheers,

Tui

You can change your view to 2D and reset it after you run that function.

Why not use Python equivalent of

 

PointAlongPoly(h: HANDLE; dist: REAL; VAR ptX, ptY, ptZ: REAL; VAR tangentX, tangentY, tangentZ: REAL) : BOOLEAN;

 

Always a good idea to check file "VWPluginLibraryRoutines.p" in user plugins folder for non documented calls.
