Ellipse cannot keep its shape, but turns into a circle

Anonymous
Not applicable
Hello!

When creating a new profile in Profile Manager, my ellipsoid contour becomes circular.

Here is what I do step by step:
1. Open Profile Manager, create new profile.
2. With Line Tool, I create a rectangle and inside of it a draw an ellipse, also with line tool.
3. Then I select Fill Tool and while holding space bar I click on the rectangle to transform it into filled surface.
4. Next I select that surface, and with Fill Tool selected and while holding Space Bar, I click on the ellipse in order to make an ellipsoid hole in the surface.

But the hole is circular and not ellipsoid.

If I do everything the same, but with a bit bigger ellipse, everything seems to work fine and the hole keeps its ellipsoid shape.

Does someone know why is this happening?

Thank You!

Please note, that it is not recommended at all, to use curves in complex profiles, because they increase polygon counts significantly! (that is one of the reasons it is set to 40 by default).
But if you don't use curves and use many straight line segments instead, then you can't hide the lines between the surfaces in the extruded profile.
Unless I have been missing something all these years.

Hello Barry,

Yes, you are absolutely right! If you need these big outside surfaces to be smooth, you need to use curves, and that is fine.

But if you have very small parts that are curved in real life (like a reinforcement bar or a metal cable), since they are so small that you will not see the segmentation anyways, it might be worth just drawing them as octagons instead (I sometimes even opt for squares and triangles).

Even in these cases you might still choose to use curves instead, but it is just good to be aware, that the number of polygons will be really high.

Maybe there just needs to be an option to hide vertices. Segmentation in 2D drawings is a horrible block of lines....

Or just a 3D resolution option that is present in most of the better scripted 3D objects. I find myself setting a lot of objects to 64 resolution when I need a nice 3D presentation.

Give it a default setting for complex profile walls and beams and for curved shells that is the same as it is now, but the option to change it if you want a smoother curve (for better presentation) or lower polycount if you have a very large model.

Having said 3D resolution being linked to a global would be nice. Overwrite elements to be simple, normal or detailed. Global 3d view quality.

A lot of objects have this option as well, but the step in detail from 'simple' to 'detailed' I find fairly large. I tend to have 'detailed' for just normal projects and then 'more detailed' for projects where interior renders are needed which is where I start dialing up the resolution in most objects.

I could see me using simple on very large projects, but about 70% of our work is large residential single homes, so not a whole lot of objects to worry about, but generally we do want to be able to have nice presentation.

The Polycount addon (from goodies) has some option for setting level of detail too.

But yeah, basically if we could have the same options that we have for library parts for the other 3D tools, it would help
