Michael,
"I'm not quite sure about STEP, I'll take a look at that."

According to the help file in Solidworks, STEP AP203 does not handle colour information. Whereas STEP AP214 does handle colours.
Of course there are a bazillion STEP APs so I don't have a clue about the rest, all I know is 203 is very common and 214 is sort of common too.

Thanks Colin for the new file. I'll check it out and let you know what I come up with.

Thanks Michael G. for the clarification regarding nurbs vs. polygon geometry treatment. I only use these crossovers for reverse engineering purposes for non-exact geometry extractions.

Thanks again,

Michael T.

It sure would be nice if STEP was not as confusing as government bureaucracy tax forms... :)

Just to make things a little more confusing there is apparently a "second edition" of AP203 that increases overlap with AP214: http://en.wikipedia.org/wiki/ISO_10303



I seem to remember that there was actually a bug fixed in the HarmonyWare STEP exporter for color information that was causing NX4 to crash when it read it in, so at least at one point colors were going into STEP files out of MoI but I'm not sure if this has possibly changed with an update of the HarmonyWare libraries.

Hi Colin,

I finally generated the MoI file from your OBJ file, unfortunately even zipped up it is over 31MB. I'll see if I can get it smaller to post here.

Regards,

Michael T.

Hi Michael T,

Glad to hear you've managed to do something with the second version.

If you want, maybe the other option might be to send it to me via YouSendIt as it's FREE for up to 100MB?

If that idea appeals to you then just PM me for my contact details.

regards Colin
