I have a client that is having trouble with dimensioning an elevation. The view needs to be and elevation of some joinery. The easy way to dimension this is to use sheet layers and viewports.
The plan viewport is easy to deal with. Put the dimensions in the design layer, the same layer as the walls and cabinets.
The Elevation viewport is different. If you place these dimensions in the design layer, you will not see them in this viewport, they will end up in the plan viewport.
The trick with elevation viewports is to add the dimensions to the Annotations part of the viewport.
Right mouse click on the viewport.
Choose Edit Annotations.
This takes you into the viewport annotation editing area., Notice the button at the top left to exit.
Now you can add the dimensions.
When you have finished, click on the Exit Viewport Annotation button.
There is your drawing.
