Path
Id prefix: PATH · Elements: exactly two · Selection filter: VERTEX / FACE / EDGE · Entry 14 of 16 in the panel's + dropdown
Path keeps a point of one component on an edge of another, the way a pin rides a track or a roller follows a rail. Pick the point that follows (a vertex, or the centre of a sphere, a circular edge or an axis face) and the edge it follows, on two components, in either order. The edge can be straight, circular or a freeform curve. The point is free to slide along the whole edge: drag the component and it stays on the path; turning it is not restricted.
Tick Fix position to hold the point at a set place along the edge instead: Along is the percentage of the edge from its start, and reverse measures it from the other end. On a closed edge (a full circle) 0 % and 100 % are the same place.
Parameters
| Parameter | ||
|---|---|---|
elements | the following point and the path edge | Either order; the edge is the path. |
pinAlong | boolean, default false | Hold the point at along instead of letting it slide. |
along | number, default 0 | Percent of the edge from its start. Expression-capable. Read only with pinAlong. |
reverse | boolean, default false | Measure along from the end of the edge. |
The point is held on the edge itself, between its ends; it does not run on past them along the edge's extension.
