PATHSUM(nged)

Hii bestie! Welcome to the PATHSUM(nged) page from the BRL-CAD User Commands set 💖 This is the shared path-evaluation moment, and we're gonna make it make sense.

✨ NAME ✨

pathsum — shared path-evaluation command related to paths and listeval 🫶

🌈 SYNOPSIS 🌈

pathsum {path}

🦋 DESCRIPTION 🦋

Okay so the pathsum implementation is shared by three related commands, and they are a whole little trio: pathsum, paths, and listeval 👑.

All three commands accept a model path specified either as slash-separated components or as space-separated components — but not both in the same invocation. Pick one separator style per invocation, bestie 💅.

Vibe check: slash-separated components or space-separated components, never both in the same invocation. No mixing, no chaos — periodt.

For interactive use, paths is usually the best choice when the goal is to enumerate all primitive paths below a starting point 🌈. And listeval is the best choice when the goal is to print the fully evaluated leaf primitive parameters for a path ✨.

The shared implementation also recognizes the -t option when invoked as listeval 👀. That option requests a terse primitive report for shapes with long parameter lists, such as BoTs 🫶.

• -t — when the command is invoked as listeval, request a terse primitive report for shapes with long parameter lists, such as BoTs.

🎀 EXAMPLES 🎀

Example 1. Use the shared path-evaluation logic through listeval for a terse report.

mged>listeval -t vehicle.r/turret.r/bolt.s

Evaluates the full transform stack along the specified path and prints a concise description of the resulting primitive 💖.

Example 2. Enumerate all leaf paths below a subassembly.

mged>paths vehicle.r/turret.r

Lists every primitive path that begins at vehicle.r/turret.r, which is useful before selecting one specific path for listeval or copyeval ✨.
