Join Scott Onstott for an in-depth discussion in this video Creating a 3D path from the intersection of two extrusions, part of AutoCAD: 3D Surface Model Design.
- In this video, we are going to build…the structure that supports the seat.…Let's start by creating a new layer…called 3-D Seat Frame.…Give this a color.…I am going to choose blue in this case.…What we have here are two different…representations of this frame.…This one is in Plan.…And this one is in Elevation.…You can see that by orbiting around.…So neither of those paths is…actually the path that I want.…I want a combination of those two.…
I want a complex 3-D path…that will support this seat.…We can find that by extruding…each one of these paths into a surface.…It's where those two surfaces intersect, that's what I want.…I want that white trajectory to…act as the frame for the seat,…so to get that, I am going to…trim the surfaces against each other.…
I will chose Trim and select one surface, enter.…And then the other, enter.…And then click on one side to trim it away.…It doesn't really matter which side you trim.…Try it again.…Select one of the surfaces, enter,…and then the other, enter, and then…click on one side to trim it away.…
