[Modify Custom Objects Properties]

I made a custom object (plugin) based on the schematic pipe example. Now I would like to change properties values (parameters) using a script.

How can I access these variables? (I have already a handle reference to the object)

thanks a lot

[Points Coordinates along a Polyline]

Hallo, is there a way to read point coordinates along a polylines? This mean: I draw a polyline, then I need to read the x,y values at given intervals along the polyline (i.e. every 5 cm), (therefore it is not useful to read the vertex coordinates because I need more points than those I used to actually draw the polyline).

Thank you very much for ypur help
