Joist extensions offer special powerful features. The area to be covered is digitized. The joist spacing and joist width are entered. The length rounding is selected from a list. A pitch can be specified for sloped joists such as roofs. You can then:
- Rotate the joist orientation to any angle
- Move the starting point for the first joist
- Remove or insert individual joists
- Double up individual joists
The joist layout is visually displayed. You can also get a count of the different lengths needed and copy it to the clipboard.
