If you used the "convert t symbol" from the tools menu (not the edit toolbar), this takes the whole 3d model and makes it into a symbol. This could be a very large symbol which could cause the plan bloat. You need to delete the symbol, save the plan, reopen it, and save it again to get rid of the extra data. Something silly about how the program can only find unused symbols when it opens the plan so the file size won't change until you save it. On a side note, in newer versions of chief you can place an outlet directly on cabinets. In older versions, you could convert a wall outlet to be floor mounted and then bump it up against a cabinet.

It looks to me like those two gables and the hip corner are confusing Chief. See if you can simplify the situation if it will start working better. In any case, I would post our plan or send it into tech support.

When you see strange things in the camera view, does rebuild 3D fix anything? Sometimes this will fix strange things. If I ever have problems with the "replace" tool, I will go into the dialog and change what I want instead. If you haven't done so already, you should send this into tech support.

I just made the "hole" a normal polyline using a solid fill and the invisible line style. This is what I use pretty much anytime I want to create a mask. This seems to work pretty good unless you need a real hole, like for a counter top or something.

You can click to to place a point light but if you drag you can create a spot light pointing in the direction you want.
