Join Scott Onstott for an in-depth discussion in this video Rotating an object with the Reference option, part of AutoCAD: 3D Surface Model Design.
- Our next task is to copy the disc brake caliper,…that we need in this location, from the rear axle.…I'm going to change to wireframe,…and the display performance…is a little smoother in wireframe.…u + c + s, enter, enter to reset the coordinate system.…Then copy this object from some arbitrary location nearby.…And I'm just going to place it over here somewhere…in the vicinity of this caliper.…Now, I'd like to look at this from above,…so I'll click top on the viewcube, and zoom in there.…
Move, this object, from a center point,…to the center point down here.…And to acquire the point you kind of have to move…the mouse around until you see that,…little plus symbol highlight.…So now at least the hydraulic cylinders are centered.…We now need to rotate, this object from the center.…I'm going to use the reference option for the rotate.…The reference angle is going to start at the center,…so I'm going to type at, enter, turn off ortho.…
The second point is right here,…at the center line of this bar,…and then the new angle is going to be here.…
