Cad Questions
- I can't change the color of the block referenced in my drawing. (Or the text color)
- What layer is the block created on? Blocks should be created on layer 0 and the color should be "by layer" not a chosen color. If these criteria are not followed, you cannot change block colors inside reference drawings no matter what you do. Text attributes in blocks existing in a drawing cannot be redefined even if the block has been. The block should be remade, and text attributes should be created on an appropriate "text" layer.
- I (froze, changed color, linetype of, etc.) an Xref layer on my working drawing, but I still see the entity even after I regened.
Did you regen in model space too? Type regenall.
- I can see the reference drawing on my monitor, but when I plot it, I only get a border and title block.
What layer is the Xref on? Is it frozen or turned off? Is it on the Defpoints layer? Remember Defpoints does not plot!
- Why can't I get rid of these unnecessary layers? I've erased everything, including all the blocks, and purged many times.
Type "Block" and list all blocks still defined in the drawing. Insert these blocks and explode them, and note the layers. Sometimes the offending layers are defined by blocks still in the drawing, but no longer inserted visibly.

What is the difference between "Attach" and "Overlay" when inserting Xrefs into another drawing?
The best rule of thumb for using "Overlay" instead of "Attach" is when you are working on a drawing that wouldn't be referenced into another drawing. For example when working on a final plot plan of city.dwg, (the drawing that has the border and title block) the bldg.dwg referenced into it would only need to be an overlay. If you are doing piping and need the bldg.dwg for a reference then you would want to "Attach" bldg.dwg into pipe.dwg if you also wanted to see it in the final plot plan (city.dwg). Also use overlay when it is unnecessary for others to see those xrefs when referencing your drawing.
