Curviloft problem... need help.

First advice is to post an SKP file of the part who has a problem!
In save as V7 if possible for a more large audiance!

V7
Bought a Minitel II?

Good idea, here it is:

canopy.skp

Rich O Brien

You jump from lofting 27 edges to 45 edges in one step. Then it goes up to 52 edges and back to 45/48 edges. More forward planning is needed.

@ Gilles : no,no always old minitel just another less old version of SU! So 2 versions in the same time! Transistors will be superheat overheat!

So It was a good idea to post the file because an image or a text are never sufficient!

Ps
Any reason for have perimeter's section not welded ?

ok, I see. Is it necessary to have an equal amount of edges before lofting them? And if so, how do I build the ribs in order to archive that, is there maybe a tutorial out there? and how did you even count the edges? Sorry for the amount of questions I have

Perimeter's section not welded? I'm afraid I can't quite follow...

Double click the face to select face and edges

Shift click face and bottom edge to deselect these

Window > Entity Info to see number of edges

This...maybe that is not important...

Thanks, thats good to know. So the point is, I have to plan ahead and make sure that the ribs have the same number of edges. But how exactly do I do that? What I usually do is create basic square planes with the dimesions I want and then round them off, using the curve tool. It turns out they have completely different amounts of edges, so later curviloft runs into trouble.
How do I create ribs with an equal amount of edges from the start? And is there a way to repair the ones I allready have?

What exactly does that image show, Pilou? What do the yellow sections mean? I'm sorry, I'm kind of a noob when it comes to this kind of stuff

Just that the perimeter is composed of different curves not welded (click on it and you will see that I say

With native tools you can't weld curves or lines so you must use a plugin
the more practical for that is Recurve by Diggsey (on Right Click)

But one more time maybe in your special case you need to have this segmentation of curves!

I found with curvizard, Cleanup contours for all curves, then simplify contours for some of the curves with larger segment count leaves you with only a couple places to fix by hand. But I think the contours show too much concentration of edges in some places and overall I would think you'll get better results with fewer and more evenly spaced segments. Rich is right and knows best how to do this sort of thing. You could also work on this with half the canopy.

I also worked at 10 time the size for good measure.

How do you arrive at the correct section and draw those curves?

Thanks friend, I'll give that a try.

Thank you so much pal, I finally solved the problem, thanks to curvizard, which I had never heard of before you told me.
All I did was simplify all the cuves, it helped a ton: there is not a single imperfection to be found in the resulting model.
The model on the right is the new one.

Thank you, pbacot!
