I've added a lot of dimensions to my plan, and would like to delete them to start over. Is there a way to delete them other than selecting and deleting each one individually?
You can either completely delete your automatic and manually drawn dimensions, or you can simply turn off their display so you don't have to see them while working on other parts of your project. First we'll discuss just turning off the display of your dimensions.
To turn off the display of your dimensions in floor plan view
With your 2D floor plan active, select Tools> Display Options .
Scroll down to the Dimensions, Automatic and Dimensions, Manual layers, and remove the checkmarks from the Disp column.
Click OK, and the display of your dimensions will be turned off until you are ready to turn their display back on.
If you want to completely remove all of the dimensions in your plan, not just turn off their display, you can follow the steps below.
Removing dimensions from your plan
Select Edit> Delete Objects , and in the Delete Objects dialog, move the radio button to All Rooms On This Floor.
Place checkmarks next to Manual Dimensions and Automatic Dimensions.
Note: If you choose to delete Automatic Dimensions, a Question dialog may display if you have dimensions sent to auto refresh within your Default Settings. Click Yes within this dialog to turn the auto refresh of dimensions off so that Automatic Dimensions can be deleted.
Finally, click Delete and all of these dimensions will be removed from this floor in your plan.
You can repeat this process for any additional floors in your plan that you want to remove dimensions from.
