Controls whether model space can be accessed by double-clicking in a layout viewport.
| Type: | Integer |
| Saved in: | Registry |
| Initial value: | 1 |
Turn this system variable to 0 if you have annotations in paper space, and you don't want to activate model space in a layout viewport unintentionally. You can still access model space with the MSPACE command.
| 0 | Prevent access to model space |
| 1 | Allow access to model space |
