Advance Steel allows adding custom treads to the spiral stair macro.
To create a user tread for a spiral stair you must follow these steps:
1. Create the step, in a newly created drawing, using the UCS located in the centre of the central post, on the top level of the step, and the X-axis parallel to the step nose.
Note: The tread can be created with several parts of different materials.
2. Save the drawing in the following folder:
To import the tread into the joint you must:
– Select “User defined” from the “Tread type” drop-down list (see the first figure).
– On the “Tread dimensions” tab enter the name of the drawing in which you saved the created tread (see the following figure).
