How to deform ovalish object

rumcajs

You can't have a losange or a 4 segment surface so a polygon if these 2 triangles are not on the same plan!
You will have always 2 triangles!

OK. then there could be solution to correct triangles which are created when you create some line. I will show image, what I mean, wait.

Maybe that is not good example...

Projections will be very useful, but does not solve actual problem. And how can I change division number? I tried enter, tab, f4, f5, nothing helped.

Try tools on surface by Fredo 6
It's useful for draw on curvated surface!

for your triangle that will be not a "flat" triangle because you are on curvated surface!
So a curvated triangle

rumcajs

Then I need to transform the curved faces to flat faces.

pilou

If you flat the "rectangle" some faces around it will be deform too

rumcajs

Pilou, I have opened the document, selected the object and checked the window Soften Edges. There are 0°. So it is really not object with curved faces. Maybe there some conversion happened without me to be aware. Strange. All lines are no dashed no, but I don't remember that I would do some conversion.

So there is not a way how to arrange two planes on the way, they to be on the same plane?

pilou

kill all segments where is the rectangle
draw the rectangle and fill the holes around it with new segments

Do you know

cleanup.rb?

This is not exactly what I need, but similar and interesting.

You have a better one with the same name Clean Up by Thomthom

If you use the previous Projection by Didier Bur, It's a game's boy to make parallal in any direction with it!
and any number just redraw one from the last

or this one Edge tool Divide face by thomthom

I did it in different way:

Side view:

But it is slow work. It took me few minutes to make the lines parralel. Then I used Created faces tool from utilities.

You see that it is possible to do it. Hence now I need only plugin to make two lines parallel. Or 2x2 parallel. Is there some for it? I did it just with my own estimation (just observing/comparing) because I don't the technique to do that accurarely.

Did you wanted to say boy's game?

The guy does nice plug-ins, nice icons and it look really useful in practice. I only had really big problem to understand his English in the video so I capture 4% of the content.

See the "Co-linear Edges" - this look like this toy could do the job I need. Don't you think? Thanks for link.

Do you understand how the to control the colinear tool?
What I must to do if I want to make the two lines of the face paralel? (same image as above). I try and it nothing did to my model...

for the the parallal edges

TGI3D - cross section tool : error: Cannot resolve cross seciton.

This problem can occur, when the program has has some dilemma. In the tutorial with wine glass, there is a cylinder and the instructor deleted at least top of the cylinder. In the case, that I create cylinder, which top is different shape or different angle then the bottom, than this problem will occur. The solution would be simple. Either delete top of the cylinder, or bottom, or (maybe), to draw one more circle on the face of the cylinder - I would use Tools on surface.

To deform faces, I found very useful, fast and simple to use this tool:

TGI3D: move

It is much more better then LSS deformation functions which are too slow (and create extra group, which is not needed in my case)
