In X12, you'll need to do this with either a roof plane or a ceiling plane. In order to use a ceiling plane, you'll need to have a roof above it and remove the ceiling.

Not sure about commercial though. I don't do commercial.

Local code in Houston is 21"

Feel free to call me this evening if you like. I might be able to help you. Tommy 832-754-6160

I don't think the amount of driveways is the issue. I can do 3 driveways on a terrain, and it cuts the curb just fine in all three driveways. Be sure you're using the driveway tool, not a driveway polyline. I'm in X12 though. It might be different in your version.

Try going to Preferences>Architectural>Roofs>place a check in the box for Automatically place roof intersection points.

There are many ways to do this. I think the easiest work-around is to place your post manually however you want. Use the slab tool to make the rock base and make it as tall and wide as you want. Center the slab over the post. I usually do this in a blank plan and size the column to your specs. Take a vector overview and save it as a symbol. Use the symbol in your plan. For the post, if it has crown mold at the top and or trim pieces (moldings) that wrap around the post at different heights, then I'll usually make the post using a soffit tool for it works very well and you can add multiple moldings to it and adjust the height of each molding. So many ways to do this just depending on the look. I also call this a type of craftsman look.

Here is a brief description. I used a crown profile from Chief and combined it with the other profile I made.

Make a molding profile and use it for your lintel for the window.

No, that option doesn't work for me in X12. Chief should get rid of that as on option unless it works in newer versions. If I remember right, you had to import the .alb files into a much earlier version like X1 or X2 first. Then export it as a .calibz file.

Yes, "Control" drag into place.

I have been using an Epson WF-7840 wide format printer for a few months now and am happy with it. It lets me scan surveys that are 11"x17" which is helpful for me. Prints up to 13"x19".

I would approach this the same way as Ryan suggests.

Also be sure walls are properly connected.
