Extrude to dome

[aaron]

Hello All,

I am a very inexperienced CAD user so I'm not sure if this is a trivial question. In 2D I have some spline curve that I extrude into 3D and I want to make a "dome" with the same contour. I can't fillet it because the geometry is too complex. Is there some sort of "variable" extrude where the extrusion distance is some function?

Thanks,
Aaron R. Shifman

Hi AAron,

depens on your design intent.

You can do it in many ways. Which dome?

Your fillet radious is too big?  Try reduce it.

You can use extrude..revolve..surfaces..sweep..loft...etc

But if you have no so much experience with the cad in general it would be better understand first the basis of the 3d parametric modeling.

Attached  a simple example of dome.

Hi Admaiora,

Thanks for the quick reply, and that's exactly what I'm looking to do, except that when I filet it, I specify a full face fillet and it cannot be performed because the geometry is too complex. And I'm not quite sure how to use a revolve to accomplish this. 

I have attatched a copy of my model and if it's not too much to ask would you mind breifly looking at?

Thanks,

I don't think it is really "perfect".  

Your Sketch did not have any dimensions - so I did not try to get perfect geometry.

Check carefully near the "pointy" end.

Hey could someone please explain exactly how this was done? Im struggling on something similar over here:
