Dimensioning 2d sketches in a drawing

Hello,

I'm new to SolidWorks and to this forum. I hope someone can help me.

I have several views in a drawing. I need to add some 2d construction lines to dimension to. In one view it worked fine. In another view I added my construction lines but when I try to select them to add a dimension I can't. It acts like they don't exist!? Frustrating. What am I doing wrong?

Thanks

Terri
