This section provides help with the representation of a sliding door with a roller box as an obstacle.
Step 1: Measure a door.
Step 2: Under the Shape tab, select the type of Passthrough.
Step 3: Click OK.
Step 4: Click on any side of the wall to indicate the door opening (even though it is not there).
Although the sliding door has no overlay, you have to click again on any side of the wall in the plan so that the door is inserted as a passagethrough.
Then measure the roller box and the door leaf of the sliding door as an obstacle.
