✨ ivdowngrade — bestie edition ✨

okay so real talk: ivdowngrade is the little glow-up-reversal tool from the General Commands Manual section 1, and she is here to take your fancy Inventor 2.1 files and dial them all the way back to Inventor 2.0 or even 1.0. vintage era. retro vibes. no cap. 🎀

🌸 NAME 🌸

ivdowngrade — converts Inventor 2.1 files to the Inventor 2.0 and 1.0 formats 💅

✨ SYNOPSIS ✨

ivdowngrade [-v targetVersion] [infile outfile | infile ]

🦋 DESCRIPTION 🦋

so here's the tea, bestie: ivdowngrade reads the input file infile and converts it to the Inventor format you picked with -v targetVersion, and that target has to be either 1.0 or 2.0. if you don't pass the -v option at all, she'll just make you an Inventor V2.0 file, which is lowkey the default vibe. 💖

the input file can be in Inventor format or VRML format — either one is fine, she's not picky. the output, though? the output will always be in ascii format. periodt.

and if you don't specify an output file, ivdowngrade writes to stdout. and if you didn't specify an input file either? she reads from stdin. she's flexible like that. 🫶

🌈 EXAMPLE 🌈

ivdowngrade -v 1.0 foo.iv moo.iv

downgrades the file foo.iv to Inventor V1.0 format, writing to moo.iv. iconic behavior.

ivdowngrade goo.iv

downgrades the file goo.iv to Inventor V2.0 format, writing to stdout. slay. ✨

💀 NOTES 💀

okay now the serious part, bestie, listen up. because of the differences between the 1.0 and 2.0 file formats, some data may be lost during the conversion to 1.0. 😭 for instance, the 2.0 file format for SoSeparator contains fields for caching and culling, but the 1.0 format for SoSeparator has no fields. so that information just… evaporates during the conversion process. gone. not me crying over culling fields 🙈

no data is lost going from the 2.1 to the 2.0 format. that one's safe, you're fine, breathe. 💜
