Hello All, I am trying to rotate a block. The axis of rotation is its lower right corner, I then want to use its upper edge as a reference to another point. So its top edge would be inline to this point, I cannot seem to figure this out without doing a bunch of math and using angles to rotate.
Don’t use math. Most likely SketchUp will have an accurate way to do what you want.
Your description doesn’t make the desired result clear enough. Share a file as @DaveR asked above.
Not sure if this will work, here you can see I have basically a roof rafter that I want to rotate about its lower right corner and snap its top edge to the top of the block at the lower left.
As @Wo3Dan shows, the Pie tool is a great way to establish the correct angle in a case like this. An alternative would be to draw the rafter at the desired angle in the first place and skip rotating it altogether.
I originally was just setting it to an angle, however the angle was not always known and math ensued. I’d rather sketch up snap to a point. When I gave it angles and built off those dimensions I would end up with compounding errors as the model got more complex.
The pie tool is an extra step but looks easy and faster than measuring and doing math.
