Hi @Anonymous,

Without seeing what you have in your drawing this is a bit tricky to answer.

I suggest that first you set your dwg units with the UNITS command. It sounds like you want to set it to architectural

Then, as a means to help, I draw a 6x6 inch square in modelspace.

Now, I switch to Layout 1. I am going to apply a Page Setup that is using a Letter size piece of paper (8.5x11)

Next, I can resize my viewport by clicking on it and then using the grips to make it bigger

If I double-click in it I can enter the model. I can now set my scale for the view of the model by selecting 1:2 from the Scale List.

Now for the dimensions.

I like to apply a linear dimension to the square in modelspace so i can see what the current dimension settings look like.

The extension lines, arrow heads and text height can all be a bit bigger in my opinion so I use DIMSTYLE to modify the dimension style being used.

I go to the Arrow size  (in the Symbols and Arrows tab) I will change to 1/4"

I will change my text size to 1/4" as well (Text tab)

I then move to the Primary Units tab abd select the Units Format and set it to Architectural

I like the way these changes look so I am going to keep this dimension style for later use.  I can copy this one dimension and place it into my acad.dwt template file. Every time I start a new drawing based upon acad.dwt, this definition for dimensions should be present. Of course, it is a good idea to check the font being used and to give the Dimstyle a unique name before putting it into the template.

Let me know if this helps. If you can attach a sample of your drawing I am happy to look at it to help with these steps.
