Hi, I'm also trying to create this ladder type with the route command, but I'm having trouble converting it to a ladder after defining the output line. Can you write the steps more clearly in order? Thanks, good work..[/ quote] Hello, In the relevant staircase, area number 1 was created with the route command. The exit line of area number 1 was drawn in the direction of the arrow. The ladder was converted into a ladder with the Create new ladder command in the auxiliary toolbar. Then, respectively, 2,3,4 Areas and 5 were created with the route command. The exit lines were drawn in the direction of the arrow. It was added to the stair created with the Add Ladder Area command in the stair assistant toolbar. Good work
