Revolve angle (by K1ZRT)
Hi!

Is there any way to fix the revolve angle to a specific value when using revolve to create a 3D object? Can't seem to find it.

NVM

Got it!!! The second normal was hidden behind the rendered object.

I usually make sure there is at least one line - or even construction line - in the 2d sketch perpendicular to the Revolve axis. That becomes a handy pair to constrain the angle of the solid to any angle

The development version of solvespace also allows parallel and perpendicular constraints to apply to faces. So for 90, 180, or 270 degree revolves you can drag it close, select the 2 end faces and use one of those.

Good approach to have a construction line present else u have to fiddle with the visibility settings on the rendered object to see the small blue normal associated with the surface.

I don't understand this face constraint thing. Is it different from angle constraint on face normals?

It is different but has the same effect. If you've ever used the point-on-face constraint, you have to select a face. When you mouse over and flat face of an extrusion it will highlight in yellow unless that's disabled. Enable-disable is the 6th button across the top of the text window.

So if you highlight a face and click (select) it, then select a point, you can apply a point-on-face constraint. I use this a lot to set the depth of extruded holes so the hole will go all the way through even if I change the thickness of the object. You can see this in at time 2:05 in the video at the top of the solvespace home page. Notice the face highlight in yellow.

In the development version of solvespace:

You can select both end FACES of a revolve group and apply a parallel or perpendicular constraint to the faces. This may also be useful in assemblies.
