Hi Franz, well I'm hoping that could be one part of an extended history function. But that's going to require quite a lot of work to implement so it's rather unlikely for the v4 time frame.

Because i find this topic quite interesting and i tried it with several apps, i come to the conclusion that for your case
MoI and ArtForm is probably the best solution. I wanted also to try with ViaCAD and 123Design and Fusion 360, but
with ViaCAD and back importing into MoI i get a curve with to many control points and the other two can't import
the curves only from MoI, regardless what exporter i have used.
Can you please confirm my findings:
I created a through point spline in MoI with four points drawn, saved as .3dm and imported into ArtForm.
In ArtForm i used "Curve Edit/Modify/Modify Point on Curve" and i have now the four points, modified one
point and saved as .3dm and imported back into MoI to compare. Perfect result IMHO. :-)
[EDIT] I tested with a curve and more points (15) and then ArtForm shows/uses only 13 points while the
shape is the same. But one can insert points on a curve too, with ArtForm in case it is required.
that ArtForm uses lesser points on curve than MoI (and some of them are not on the same position)
but the back imported shape is the same.
I tested it again with drawing points in MoI then drawing a curve on them through points
and imported into ArForm to see the difference and finally back to MoI.
Red original from MoI black import back from ArtForm.
I will try it in your way, here is the wanted function in Qcad (DXF):
So export the curve to DXF, edit it in Qcad and import it again, if you like.
But I think they drew the points earlier in Moi.
i also played today with HeeksCAD and it has the function to automatically
create a spline curve from points! :-) But i could not figure out yet how to edit
splines in there and also how to export as step or iges, because no files were written.
Later then i found PolyCAD which also looks very interesting but i have to wait for
the serial.
Thanks! I have a mail from the author Marcus Bole
but alas i had not my glasses when I sent him the Computer key number machine, so i must make it again! :)
PS He don't know Moi3D! So a cool discovery for him!
Thanks for the tip with ArtForm (3.5).
In my version I cannot import *.3dm, only IGES.
Connot finde in "Curve Edit" the way to /Modify/Modify Point on Curve.
And I had to learn more about working with ArtForm, so I cannot edit points from the curve now.
Thank`s for your help.
I see, it ist really possible with these "sidestep" to ArtForm, to change the curve form with curve points and reimport to moi very quick!
