The attic wall was already there. On level 1 > select window > Cut. On level A > Paste Hold Position. Elevation view shows it in the right place. Properties show it located relative to floor 1 same as before, so it seems a negative value is not needed, although it might be if I rebuild the walls. Thanks!

Transom window above a door displays in floor plan where just the door should display. Tried sending window to the back of the display group but that was no help. Searched Reference Manual, Help and Knowledge Base with no hits.

Thank you Jo Ann Experimenting, I got strange wall behaviors, move a wall outside the building, it displays. Move it back in and sometimes it continues to display, sometimes not. Drag a wall end to open the interior to outside, some walls display, close it back up they disappear. I ended up suspecting the issue was as Solver suggested, caused by the entities from the DXF file. I've not checked back to the file, but I suspect some entities had a Z-value and the walls I traced snapped to the CADD entities which got them 'confused'. I copy / pasted into a new drawing, erased all the interior walls, imported the DXF into the new drawing and was careful to disable object snaps when drawing new interior walls. All now seems fine and I'm back to being productive.

That looks nice. I have checked all those things multiple times. Some of the "walls" are room spaces using the room divider wall style which is invisible by default. This was originally drawn in Autocad with all windows & doors, fixtures & furiniture. Rather than start from scratch in HD I made a 2D DXF file and imported it so I could trace walls, place doors & windows, cabinets, etc. using CAD lines as a guide. I still had to define window types and heights. I like to leave auto-build on as far into the project as possible, and one end of the building (it is an existing building) is on a slab down 8" from the floor of the main section which is on frost walls with crawl space beneath. For now I plan to delete it entirely and work just with the main section which is getting some renovations. My only previous building done with HD-Pro 2019 was a garage / workshop and it also had the disappearing interior wall problem, so I am about to check for program updates, perhaps re-install if there are none. But next I'll try Eric's suggestion again using different templates of which there are several predefined that come with the program. In the case of the garage I got the walls to display by selecting them individually and editing the style's materials as mentioned in a previous post. Thanks for your help!

Thanks Eric, but that did not work, walls not visible in the new drawing either,

Here is the file. Additional issues include foundation & framing not auto building. Maybe all problems are related to room designations. I have managed to make individual walls visible in 3D by editing to change a material, such as changing drywall to a color. The CADD entities are from a DXF import from Autocad Architectural.

Large interior room designated 'Unspecified' (also tried 'Living'). Exterior walls have no issues. Drew interior walls which show in plan view. Walls are not designated 'Invisible' or anything else in the list of check boxes. If a wall is selected, on the General' panel wall view pane the plan view of the wall displays but 3D rotate-able view just shows the labels 'Interior' & 'Exterior'. In Dollhouse Orthagonal & Perspective the walls do not display. Verified the wall layers are on for those views. When a room space is selected there is an outline at limits of each wall, but no wall.

Thank you!

I have made a garage with walls on a stem wall, interior slab 6" below top of stem wall. I added a roofed shed on the outside of the garage exterior wall, it has a slab floor 8" below the top of the stem wall. Before defining the floor elevation I turned off foundation auto-rebuild. The shed's defined space ends at the outside of the garage exterior wall. Problem is the shed's room definition is "removing" the foundation wall down to the bottom of the shed's slab floor. If I grip edit the bottom of the shed room limit upward the foundation wall follows along. It will follow along to any height, even above the defined top of stem wall. I need a way to tell the shed floor to stay outside the foundation wall. File attached: Barn-19-02-01.plan
