IMPORTFG4SECTION(nged)

create an object by importing the specified section

💖 IMPORTFG4SECTION (nged) 💖

okay bestie, so this one lives in the BRL-CAD User Commands fam (the manual is literally nged), and it's genuinely such a vibe — you hand it a chunk of raw FASTGEN4 text and it hands you back a whole 3D object. iconic behavior tbh ✨

✨ NAME ✨

importfg4section — makes a brand-new object for you by importing whatever section you point it at 🫶

🌸 SYNOPSIS 🌸

importfg4section obj "section_data"

🦋 DESCRIPTION 🦋

So here's the tea ☕: the importfg4section command parses a FASTGEN4 section — which you give it as one single multi-line string, no cap — and uses that to build a fresh BOT (Bag of Triangles) primitive. yes, a literal bag of triangles. main character energy 💅

It gets the structural geometry data out by parsing these record types from the string you passed:

  • GRID — the vertex coordinates 📍
  • CTRI — triangular faces 🔺
  • CQUAD — quadrilateral faces 🔷

and here's the slay part: any quadrilateral faces (CQUAD) get automatically split into two triangular faces for you. no extra work, it just happens 😌✨ The finished geometry gets saved into the database under the obj name you picked.

🎀 The arguments 🎀

  • obj — the name of the shiny new BOT primitive you want to create 💖
  • "section_data" — a string holding the raw FASTGEN4 section data that's gonna get parsed. keep it quoted, bestie, it's multi-line 🙈

🔥 EXAMPLES 🔥

Example 1. Importing FASTGEN4 geometry data ⭐

mged> importfg4section wing.bot $fg4_data_string

This one creates a new BOT primitive named wing.bot by parsing the raw FASTGEN4 geometry records stashed away in the variable $fg4_data_string. look at her go 😭💜
