I have been working with roll20 to build a campaign. I am to the point where I have to create the buildings and underground tunnels. I have a campaign that was built for 2.5 that I am converting to Pathfinder. It has an online PDF and I have been able to import most the maps. Unfortunately, there is some I have to build and I have never done this before or used these tools before.

The tools from roll20 dont seem to line up.

It is a bit frustrating. I have never done this before so I am woefully under skilled in this process. I have never done anything like this before

It doesnt have to be a Rembrant creation but I would like something that doesnt look like a 6 month old didnt build it.
