Making a 90 in a tube

[Robamobabob]

First, to J.D., I'm about to go through all the tutorials, but I have another question I'd like to post...

 

I'm making a simple tube, in an L shape, and I'm wondering how to put a 90 degree angle in it... On AutoCAD 3D, we would just build tubes intersecting at a sphere, but I can't seem to make a sphere.

 

I've linked a screen shot.

Have you tried sketching the tube profile on on plane, then sketching a path on a plane at 90 degrees to the first plane? You should then be able to sweep the profile along the path. If you use the center line as the path you'll need to constrain the end of the path line to the tube profile center. One hiccup I've had doing this is making the radius of the bend too small. Do that and you'll get a self-intersection error warning and the model won't build.

 

Hope that helps

Not the way to make a L-shaped tube in AutoCAD - simply do a Sweep in AutoCAD or Inventor.

 

but I can't seem to make a sphere.

 

Revolve, same as AutoCAD. Geometry is geometry. CAD system is largely irrelevant to primitive geometry like this.

without drawing anything else i believe you could also to a loft between each tube cross section and setup a tangent start/end. revolve, sweep, etc are the way to go

Ok, thanks, I'll try it out... Have been away from my computer for a while, so sorry for the late response.
