Converting and Prefabs

A parametric shape can stay parametric indefinitely, or be finalized into a plain mesh or an editable mesh whenever you are ready.

---

Rebuild Shape

Rebuilds the mesh immediately from the current parameters.

You rarely need it, since changing a parameter rebuilds automatically. It is there for the cases where the display looks out of sync — after reverting a prefab, or after the mesh was replaced from outside.

---

Remove Shape Parameters

Keeps the current mesh and removes only the parametric component.

The result is an ordinary Unity object with just a MeshFilter and a MeshRenderer. Use it once the form is final, you will not touch the parameters again, and you want a lighter Inspector.

---

Convert to Editable Mesh

Converts the shape into a UModeler X editable mesh, after which vertices, edges and faces can be edited directly.

The conversion does not copy the baked mesh triangle by triangle — it regenerates the topology from the parameters, so quads, UVs and smoothing are preserved.

Two cases get special handling.

Making prefabs

Parametric shapes become prefabs with their parameters intact. You can adjust parameters on the prefab instance, and the generated mesh is stored with the prefab asset.

• Structures made of a group with several parts (a chair built from legs and a seat, for example) are saved together with every nested parametric shape.
• Unpacking or duplicating a prefab instance automatically separates the mesh so each object owns its own.

Handling prefabs from a script

The script DSL has two prefab statements.

# Place an instance of an existing prefab asset
prefab "Chair" "Chair_A" @2,0,0

# Save a scene object as a prefab asset
save prefab "Table" "Assets/Props/Table.prefab"
