Hi Below are the Things I want to achieve
1. Get the block from the File location
2. Insert the Block on Drawing
3. Then Rotate this block along the insertion point
1: Issue that I facing is in Step 2 where when I run the command of fresh drawing instead of placing the block it goes to
"\nBlock '{blockName}' not found." unless I manually place the block it does not proceed further.. expected was it should had added this new block and updated the Block table accordingly..
2: Other part is Step 3 once I place the block I want to rotate it but not sure how to do place the code as when i use the rotationjig file it crashes auto ca with error enotopenforwrite.
