As much as I’ve learned about SU, alignment of holes has seemed to elude me until now. Imagine trying to place these two parts on one another while aligning these two different size holes.
I came up with a technique to aid me with this problem. Maybe others have used this technique, but I’ve not seen it in any SU tutorials I’ve seen. For purposes of this example, I’ve hidden the top face of these two parts. Before I draw the holes, I first place a line that is located along the centerline where each hole will be drawn.
I can then place the starting circle on either tip of the line and then push/pull it to the proper depth. This is completed for the holes on each part. Now I’m ready to align the two parts.
Before starting the Move operation, it helps to Hide the floor of the upper part so the upper snap point of the lower part can be seen while placing the upper part in place. I’ve also hidden the side walls of the holes for this step.
Once the upper part is precisely aligned, then all of the Hidden faces can be Unhidden.
You can see how the holes are nicely aligned. One more side benefit of having these lines in your drawing is that it makes it easy for me to rotate a part around the center of a hole.
One last step I do is place this alignment line on a separate ‘Alignment’ layer so all these alignment aids may be easilly hidden from view in one swale foop.
If you have other methods that make this easier for you, I’d be interested in seeing your approach to this problem.
