Multiple dimension formats in same file? in General Discussion Posted Friday at 04:42 PM I know that many of us would like to see more options for Dimensions. Here in Canada for example we often have clients or contractors who want to see drawings that may include Imperial Dimensions. To avoid a large number of Dual Dimensions the following is what I do & it will work the same for for mm & cm display. - Edit the Units and set the main Units of Length to whatever is the most used in the document (for example cm) - Choose Dual Dimensions & set the Dual Dimension to mm - Add Dimensions as you normally would in your document - When you need to show mm change the dimension setting to Dual Dimensions (you may want to add a custom Dimension to your Dimension Standards) - Un-check the box marked "SHOW DIM VALUE" - What remains is the mm value I can't find a way to edit the 2nd Dimension Value to do away with the rectangular brackets, so this may be inelegant, but hey, it works!
