When in a drawing I use "Convert View to Sketch" to create a block from a view. Sometimes it works great while other times it goes thru the motion and doesn't insert the block. I have learned to always create a backup copy of the drawing to use when making blocks from views since once it stops creating blocks its done. I then need to save another copy of the drawing to work with and that copy will make additional blocks.

Does anyone know why it stops creating blocks using the Convert View to Sketch option?
