Is there a way to make text and leaders appear on top of all objects in my drawings?
See how the arrows are behind the different roof pieces?
Also, I just noticed half the text is cut off on the bottom left note. In my drawing, that reads “4x8 RAFTERS @ 32” O/C".
The labels in SketchUp are floating in 3D space so their leaders can end up behind parts of the model depending on where you anchor them.
Add the labels in LayOut instead of in SketchUp. That will give you better control over where those labels end up relative to the model and they will look better, too.
