Join Scott Onstott for an in-depth discussion in this video Using the Boundary command to generate a profile, part of AutoCAD: 3D Surface Model Design.
- The next area I'd like to focus on is…right here, where we see this white shaft.…We need to fill in that space with some elements…that bridge the gap between…the drop out and the brake rotor hub.…I'm going to zoom out here and orbit…so I can get a better look at the cross-sectional sketch.…So, the area in question is right down here,…and the brake rotor actually has…a void inside of it here, if you remember.…
And we have to deal with that,…the sketch isn't quite accurate,…we need to make a change to it.…I want to get the UCS into the correct plane,…so I need to rotate it.…UCS, X, enter, minus 90, enter.…Now the XY plane is parallel…to all of these objects here.…Let's create a new layer called "3D Nuts,"…for lack of a better name.…Make it current and change the color to blue.…
Draw a line over here, like that,…so this object has to go up…and connect with this surface.…I'm going to turn off object snap temporarily…by pressing the F3 key, I'm just going to…move this over a little bit, and I can reposition this grip.…
