Step 1 — Open the Linear Pattern Tool
Frame Designer → Edit Model → Pattern Members → Linear Pattern
Why: Start pattern creation. Tip: Use preview when available.
Step 2 — Specify Instances & Distance
Enter number of copies and spacing in dialog.
Expected: Dialog shows inputs for instances, distance and direction vector.
Step 3 — Define Direction Vector
Set global direction (X,Y,Z) — e.g., Z = 1 for pattern along Z axis.
Tip: Use non-unit components for angled patterns and normalize if necessary.
Step 4 — Apply the Pattern
Click OK and inspect newly generated members.
Step 5 — Select Members for Grouping
Use Select Members → Parallel filters to grab similar members.
This speeds up adding many elements to a group.
Step 6 — Highlight Members to Be Grouped
Why: Double-check selection before creating the group.
Step 7 — Create the Group
Beam panel → New Group → name it and confirm membership.
Use clear names (e.g. Rafters_RowA) for easy management later.
Step 8: Name the Group & Enable Code Check
Enter a meaningful group name, such as Top Beams. Optionally enable Use in Code Check to include this group in design calculations.
Step 9: Auto-generated Groups from Pattern
IMDAS automatically creates additional logical groups based on the pattern operation. These can be used to assign properties or perform code based calculations.
