For a SW course I need to replicate drawings in exact detail.

I've been trying for half an hour now and I cannot seem to replicate this method of dimensioning.

Since I cannot replicate it, I shall make a screenshot and edit it in paint to how I want it to be.

Check out the image, as you can see I removed 2 arrows and replaced them with a dot, how do I do this in SW?

Thanks in advance.
