Plant primitives
ARC3D2
ARC3D2 follows Plant 3D™'s native parameter contract directly: D and D2 are half-diameters, R is the bend radius and A is the bend angle.

- When to use it
- Smooth reducing elbows without the segmented ARC3DS appearance
On this page
Step by step
- Place the elbow insertion point.
- Set D and D2 using Plant's native half-diameter convention.
- Set centerline bend radius R and sweep angle A.
- Use Endpoint/Centre/Quadrant OSNAPs to connect later geometry.
Parameters
ARC3D2(s, D, D2, R, A): D is the 1/2 diameter, D2 is the second 1/2 diameter, R is the bend radius and A is the bend angle.
Plant export
Export calls Plant's native ARC3D2 contract and aligns its native connection points to the same Designer bend convention used by ARC3D/ARC3DS.
Keep in mind
- ARC3D2 is a different primitive from ARC3DS: use ARC3DS when you explicitly need a segmented elbow.
