DimSum 0.5.350
Released October 4, 2026.
The Joist Tool is now an assembly. Rim board and subfloor are their own linked items, with clean corners, their own labels and their own estimating lines.
The same news is on the website's What's new page.
What's new
- Rim Board is its own tool, drawn on the joist area's edges. Each piece is its own item: select it, label it, or break a piece out into an ordinary item. A broken-out board still stops the joists.
- Subfloor is its own area on top of the joists, linked to the joist area.
- Edit it all from one place. A joist area's Properties has a Linked group for its rim board and subfloor, so you can edit the members without hunting for them.
- Tools → Assembly shows a tool's members. Copy the Joist Tool's assembly and make it yours: add or remove members, and change where they sit and at what elevation.
Improved
- Corners join like walls, with no gaps, inside corners included. An inside corner counts the true board length.
- New snaps on the rim: corners, faces, ends and the centreline.
- Each member hides on its own and keeps its own labels and estimating lines.
More in Assemblies.
Before you update
- Your existing jobs convert when opened, with the same counts. Only rim length can grow, by the true length at inside corners.
