I'm new so just learning, but when I place a door or window in a wall and want it 3" (lap and stud) away from the corner of another wall, I can't seem to get it to 3" - it's always a little off.
I drew a center circle from the corner with intersect snap so I know where the 3" intersection crosses. And when I move the door next to the wall and then slide it away, and use the TAB key to enter 3" - it still is not 3" - does not line up with my circle - see image.
I cannot get the door to center in the opening either - If I turn object snaps off, I can eyeball it to center. I can see the frame of the door is 3/4", so the gap I am seeing is the 1/4" that remains that shows that the 3" radius circle is not connecting - see image. Maybe I should make the door frame 1" so it fills the gap (space between the frame and the stud) that is there to allow some movement in real life. But for CAD, I want to make sure my objects are placed precisely, otherwise things go down hill from there and allow discrepancies.
Many times I place walls by this 3" (Lap and Stud), then a door/opening and then another 3" and then a wall - like for a bedroom closet. When I dimension the plan, the framers do what they should and the door fits as expected.
Same with the window. When I slide a window against a corner wall, it snaps about 1/2" from the corner wall, but I don't know for sure because it is hard to use the tape measure and see what it is snapping too. Then I drag it away from the corner and TAB and enter 2.5" - but still it does not line up with the 3" radius circle - See image.
I am new and still working through the tutorial so maybe I am jumping on this too early.
Thank you
