So I've recently been having this issue with MEP 2013. After I unistalled MEP 2012 from my computer, I notice I could no longer edit or create dynamic blocks(see error message below). I tried a reinstall, as well as a repair, and neither worked. I figured it wasn't that big of a deal tho because MEP 2014 was about to come out. After I installed MEP 2014, im getting the same issue.
Solved! Go to Solution.
do you try to copy/paste the block alone in a new drawing based on the acad.dwt ?
Is this the only command or tool that is not working for you? How are you accessing this command? Is this happening when you try to edit any dynamic block or just certain blocks? If you type BEDIT at the command line, does the Edit Block Definition dialog display?
This is the only command or tool that I've noticed isn't working. I am accessing the tools via the "Block Authoring Pallette" in the block editor, therefore the BEDIT command works. It happenes with every block, new blocks I created just to test this, as well as older blocks that already have these tools built into them. The existing dynamic blocks I had already made still work the way they are supposed to in the model space.
I resolved this issue.
1. run "regedit.exe"
2. browse to the file path below:
3. double click "RegisteredToolsPath"
4. change the file location to the following:
5. Restart AutoCAD.
