Revit Tip: How to mask text in the dimensions

Masking regions provide a way to obscure elements in a view. Masking regions may be useful in scenarios like the following:

• You need to obscure elements in a project.
•  You are creating a detail family or a model family and need the background of the element to mask the model and other detail components when it is loaded into a project.
• You need to create a model family (from imported 2D DWG files) that obscures other elements when placed in a view.

Here’s little tricks that will guide you along the way.

1. Click the dimension text, a pop up window will appear into your screen.
   
2. In the dimension value, there is two option. Chose the "Replace With Text".  Check the properties of what text style you are using. 
   
3.   For example, the text style of your text dimension is Arial and takes a look first at the Character Map. To find it easier where is the character map, use the search bar of windows explorer.
4.  Choose the Arial style, select the blank character and copy.
   
5. Back to dimension text dialogue in the "Replace With Text", press Ctrl+V. Then press Ok and Apply. 

Update: Let me know if this succeeds. I tried this in Revit 2017 but it doesn't. So the best option for this to fill in and replace. I used the "." period or the middle dot character and hide to apparent element if may coincide. 

Thank you!
