What is the two-tier entity model in XyzPilot?

XyzPilot has two entity tiers: construction tier (Points — disposable) and product tier (Lines, Arcs, Circles, Toolpaths — persistent).

Full Answer

XyzPilot distinguishes between two fundamentally different classes of geometry entity:

TierEntitiesPersistenceDelete Freely?
ConstructionPoints (P0, P1…)DisposableYes — after geometry is baked from them
ProductLines, Arcs, Circles, ToolpathsPersistentOnly if nothing downstream depends on them

XyzPilot Example

Construction tier: P0=(10,20), P1=(50,60) → used to create L0 Delete P0, P1 → L0 unchanged (baked) Product tier: L0 used to create A0 (fillet arc) Modify L0 → A0 may become inconsistent Use Undo to manage product-tier changes
