There are a few instances in archicad where a view or attribute setting can get buried behind custom components or attribute overrides. The pen settings of an opening in a wall with a demo’d window or door may not be obvious. The pocket door lines are also somewhat hidden when the door is in a composite wall; Shoegnome does a good job of explaining the solution for both.
Recently we had an issue with door swings not showing on elevation or 3d views for a custom door panel applied to a Cadimage door.
The problem is the door swing spacing (inside to outside panel faces) is set by the noncustom panel thickness. By applying a custom panel you loose access to this setting.
The solution is to make sure you set the panel width to match the custom thickness before you apply the custom panel or sash. The default is 1 3/4” or 1 3/8”; so if your custom panel is thicker, make sure you match or exceed the panel thickness in the above setting control before you apply the custom panel.
