Dimensions not working properly

This is what shows up when I use the linear dimension command(the selected line is what I wanted to display dimensions of). Please help

I might hazard a guess that your dimension style has a text height that is very tiny compared to the object you are dimensioning. So tiny that you don’t see it on the screen. If you zoom way in to the middle of the dimension line does any text show up?

I increased the height of text and it showed up, how couldn’t I guess that. thanks.

If you are working in a file that has larger objects, you might want to scale the whole dimension style, not just the text height:


Also possible to make a copy under a new name and then scale the copy.

thank you very much
