Nodes
IF / THEN / ELSE node
The Condition node compares values and exposes a boolean TRUE result plus a VALUE result chosen from the THEN/ELSE branches.

Step by step
- Add an IF node.
- Set the left value, comparison operator and right value.
- Set THEN and ELSE values.
- Connect TRUE to a compatible visibility/show-hide input or VALUE to a numeric property.
Two outputs
TRUE represents the comparison result. VALUE represents the chosen THEN/ELSE value, so one condition can drive visibility and a numeric dimension if needed.
Readable rules
Prefer named Value parameters on the comparison inputs instead of burying important thresholds inside long expressions.
Preview visibility
Show/hide rules affect the parameter preview. Returning to Designer restores the visibility state captured before entering the preview; graph preview visibility should not permanently hide the construction geometry.
Keep in mind
- Test both branches before saving snapshots so a configuration does not hide the only geometry you need to edit.
