How can I change line thickness in RSTAB?
You can change line thicknesses in the RSTAB settings.
In the menu, open "Options" -> "Display Properties" -> "Edit" or right-click the workspace (do not click on elements) and select "Display Properties" in the shortcut menu.
Under "Model Data" -> "Members", you can set the line thickness of individual member types.
If you have several modifictions that should not be used permanently, you can seva them in configuration manager and work with them when required.
For this, select in the Options menu "Configuration Manager" -> "New Configuration" -> "Display Properties" and specify your preffered settings. You can work with this setting by using the "Set Configuration as Current" function.
