Question:

The slabs under columns and walls are on different levels. When using Align with Slab, the bottoms of columns and walls cannot be aligned with slabs. How can I rapidly sync column and wall bottoms with slabs?

Solution:

1. By using Align with Slab, you can only align the tops of columns, walls and beams with slab tops, but cannot align the bottoms of columns and walls to slabs.
2. To rapidly sync the bottoms of columns and walls with slabs, you can batch select the walls or columns you want to sync with slabs, and then in the Attribute Editor, modify their elevations to Bottom_Slab_Top_Elevation.
