Super Secret: Edit Those Un-editable Blocks

This one’s for you Eric.

Intead of knocking over your cubicle because you can’t edit a block, there is an AutoCAD system variable that lets you lock your blocks from being able to edit them in the Block Editor. So if you cannot explode a block or edit in the block editor, this tip is for you.

  • The system variable is BLOCKEDITLOCK and can be set to either 1 or 0 (zero)
  • <0> = Off – Block Editor can be opened
  • <1> = On – Block Editor cannot be opened


Below shows how this variable affects “Dynamic Blocks” Usually you double click a dynamic block in order to select the block from a list and then that block will open in the block editor. But with this System Variable turned on, a double-click will only bring up the properties box.

    Hello, very nice tip. Thanks. I am having a strange block related problem from one of my clients. The block name is A$C42957A01. It was inserted in Floor-Basement. i.e when you pick it the layer Floor-Basement will show up in quick properties. But if you switch off another layer, RW, automatically the block is not visible. It means, the client, has drawn it in RW layer, messed it up and it appears in Floor-Basement. Can u help me solve this problem, by transferring to either one of the layers, Floor-Basement or RW

    Hey, so i guess is a common situation trying to protect your blocks from someone else to edit them.
    I tried this option but there is the option of “edit in place” still available, is there a chance that can be locked too?
