Issue description
Your stair design has a few treads with special or unusual geometry, and you would like to represent it in Archicad. Use Stair Edit Mode to remodel atypical treads and flight boundaries when simple node edits don’t achieve the required geometry
Solution
Option 1
- Simple angle modification to the flights is possible by simply moving the staircase's nodes
- More precise editing can be done by selecting the stair and clicking on Edit to activate Edit Mode
- Here, you will notice we can select different elements from the stair, such as the tread and riser cladding. As shown below
- Note that when selecting the stair by clicking on the tread, you will not be able to directly modify the steps' structure, instead, you will be reshaping the cladding.
- To edit the structure, make sure to select the Stair by clicking on the Flight's outline, opposite to the staircase's Reference Line
- As you click around the edges and nodes of your stair, you will notice in the Pet Pallet that you can add nodes, curve edges, fillets/chamfers to corners, and other common modifications.
Option 2
If you have a situation in which you find the stair steps cannot be modified to your liking (for example, the picture below), you can use slabs to supplement the treads.
- Create a Composite for the Slab tool that matches the materials and the thickness of the staircase Riser and Tread Cladding.
- Using the Slab tool with your new Composite, model your step extension.
- You can convert the Slabs to Morphs for further editing
- Select the Morphs, Right Click > Merge
- In the Morphs/Slab Selection Settings, change the Element ID to match your Stair's Element ID. This will help you isolate the element for Schedules, Graphic Overrides, Find and Select, etc.
- Return to Edit Mode on the stair to make final adjustments so the main stair neatly matches and visually integrates with the new steps
