Best in general is to redraw with curves above the existant "polylines" ! ;)
Maybe one minute in your case for this little piece!

Hi Paul, I found one problem area in the curves, there is a little tiny line segment in this area here:







I think that's not the only problem though.

I rebuilt all the dxf-polylines with curves through points. For me it took me a little more time than for Pilou :).

But the more time consuming part was to snap all sections together and keeping all lines flat.

- Is there an advise, how you snap the perpendicular Curves efficient and keep them snapped?
- Is there an easier way to look for the intersection points? I always used ->curve->insect and constructed points.

I also found that the closed crossections introduced problems at the backside. It was no longer flat. So I build it afterwards from the edges.

The outer shell took some additional time, but I was much faster, because I knew the problematic area already.

At the end the result looks quite promising.



The slicer gives an estimated printing time of 9 hours per half. We will see.



I will add some photos of the printed form, when we are ready.

Thank you again for your help. It showed me the my problem could be solved with MOI.

Best Regards,
Paul

Hi Paul, it looks like you're making great progress now!

re:

There isn't really any built in tool for doing that. Depending on the particular situation some kinds of strategies could be helpful like have some extended flat reference lines to target.

The Construct > Curve > Isect command is the main way to check for intersection points. The Network command can actually tolerate curves that do not exactly intersect. That can be messy at a major nexus point but out in the middle somewhere it can be ok.

Sometimes it can be good to overbuild something and plan to hack excess areas off with a cutting line rather than trying to do the initial surfacing directly to a target shape...
