Mr. yselimcamas, **Wall plaster may be inactive (unmarked) in the drawing details section of the layer settings. ---I looked at your project. There is the above situation. Wall plastering is turned off in layer settings. When you open it, you will see the plasters. Also, Autosave (in general settings) in your project seems to be set to 1 min. You cannot work this way. The program records per minute. If you do this time like 30 minutes, you will work more comfortably. ---For now, the plaster drawing in the section is not given automatically. If you draw the walls as a layered wall (you can define a plastered wall layer by entering the combined materials from the settings menu). ""Can't an adjustment be made to the stair railings? he puts a railing on each step on one of the stairs, on one of the 2 steps... also, I think the railing turns are wrong.. is it user error or due to the program."" with hide railing If you want, you can remove the railings on the wall side. You can change the number of guardrails on each arm and landing line with Edit . In addition, if you want to move the place of the railing on the step to the right and left, from the staircase settings (stair edit dialog), click move balustrade under the 3D display tab, select the railing you want to move from the perspective in this dialog and move the mouse to the right. You can decide its place on the step by moving it to the left. There are no mistakes in the guardrail turns. **When the section is taken, if you select the roof block and enter and exit its properties, it will be refreshed and will appear correctly. There is a small regenerate problem there. In addition, you tried to draw each surface on the roof with the roof surface and define details separately for them. I don't think so. Draw a single auto roof. Then for example go into the rafter and say "apply to all eaves". Here is how I saved your project. Good luck with
