See if this thread helps:

...and (just to clarify) are you exporting from plan view or from the layout? From there, without seeing exactly the step by step process you are following, it would be difficult to troubleshoot. I'd recommend calling tech support where they can walk through the process with you to help find the culprit. Best of luck...hope you aren't on a time crunch....nothing more fun.

Perhaps play with the 'feet' vs 'inches' scaling units during the export process...?? https://www.chiefarchitect.com/support/article/KB-00013/converting-plan-files-to-dwg-or-dxf.html Also, make sure you are exporting from the plan file vs the layout file. Just a couple of quick thoughts.

Your ridge is sloped because the baselines or walls they are following are not parallel to each other. Parallel roof baselines are needed to have a level ridge.

Try adjusting the Z axis.

Referencing the entire model to the other plan is a good option that eliminates the need to create the symbol: https://www.chiefarchitect.com/videos/watch/193/offsetting-the-reference-display.html

You have multiple instances of 'Rabs Drywall'. Merge them together and that will remove your line.

The link supplied in previous post covers most of that...following those direction, select the hatching after it has been placed, open it's dialogue box and change the pattern to solid fill and choose desired color. OR before applying the hatching, double click the tool and designate the fill then the subsequent walls you paste it on will have that designation.

Agree...while calling is pretty painless (just did this the other day)...having the ability online would be preferred as then it can be done any time of the day or week. EDIT: uuuh...looks like some one deleted their post prior to mine...so now my post that was in response to theirs, doesn't make sense....oh well.

Define/create a room under the soffit with invisible walls OR manually draw in the soffit with a 3D solid.
