DrawView update ISSUE
I am developing a kind of, simple, "tweak tech" as follows:
The second selected "tweak point" coordinates are used to place the first selected "tweak point" so
both points result at the same coordinate, then the modeling command c4d.MCOMMAND_OPTIMIZE is called,
sometimes "artifacts" lines appears, I noted such lines always point to "wolrd axis".when zoomming (finger mouse wheel) such lines desappear as shown in the .gif file,
I have tried the following with little effect:c4d.DrawViews(c4d.DRAWFLAGS_FORCEFULLREDRAW, bd)
c4d.EventAdd(c4d.EVENT_FORCEREDRAW)Is the an effective way for updating the view?
thanks in advance.
# The call secuence as follows: def MouseInput(self, doc, data, bd, win, msg): ... def ExecuteTweak(self, bd): ... self.DataDict[TP_Object].SetPoint(...) # setting the point at the second point coordinate self.DataDict[TP_Object].Message(c4d.MSG_UPDATE) ... self.Optimize() # OptimizeSettings[c4d.MDATA_OPTIMIZE_UNUSEDPOINTS] = False c4d.DrawViews(c4d.DRAWFLAGS_FORCEFULLREDRAW, bd) c4d.EventAdd(c4d.EVENT_FORCEREDRAW)

Hi @mdk7b2,
Thanks for your patience and sorry for the delayed answer.
I can clearly see the issue you're struggling with, however, I cannot reproduce it without a sample code. Without the code that demonstrates the issue I can only speculate on possible reasons, for example you might want to check c4d.MSG_POINTS_CHANGED and c4d.MSG_POLYGONS_CHANGED messages to explicitly declare the change of the object's geometry.
To ease any further investigation, please, share a miminal code snippet that shows the issue.
Cheers,

I have testesd both option you mention with out solving the issue, I even tried c4d.MSG_CHANGE, soon I submit a sample code.
Also I'll try a different approach with WELD command, i will search the forum on how to use it since the help doc on this command is not clear.Again: soon I submit a sample code.
Thanks

ISSUE SOLVED
Issue caused by a mess in the normals, yes my little knowledge in 3D makes me forget
objects are not only vertex and polygons also normals.Check sdk_support(at)maxon(dot)net
Thanks Maxon
