Excuse me, when Tianzheng cad was inserted into the library, it was prompted that the block could not be found and could not be extracted. What's the matter?

Solution: When using Tianzheng master library to store new drawings, it must be done in Tianzheng's default Drawing 1 window. If the storage entity is not in this window, you can copy the new drawing to the drawing 1 window before warehousing.

If a block can't be found and extracted, you can put it in the warehouse by this method again and you can use it. All entities must be placed on level 0, and all colors are white.
