I'm writing a script to generate SNOT roads but I have encountered a problem. As you can see the bricks in the attached file follow a neat curve. However the rotation of the parts around the z-axis is backwards. How do I fix this in the bricks' rotation matrices? Here's the relevant bit of code in the script I wrote:

Hi I'm working on a spring generator for LDCad, and was wondering how far I should take the details.

I've looked at the existing springs in the library, and noticed they don't have conditional lines in the way I would expect them. They also use static lines around the (very low res) wire edges.

Is this on purpose or pure some performance issue ?

Anyway this is what my current code generates (no lines at all).

I installed MLCad 3.40 a while ago but didn't bother with importing MLCad.grp. How do I do so now? I've copied the file into MLCad's directory but MLCad ignores it as far as I can tell. Thanks.

I thought we expunged all Non-CA parts by now? Thus the Non-CA section in the legal info should be redundant.

EDIT: gee, can we get URL auto-linking? I keep forgetting to put url tags just for this forum...

What tool can I use to update all my models to use the newest parts? (E.g. parts that have been renamed or moved, etc..) Thanks!

I can't use MLCAD since Datsville (the model I am trying to update) has nested MPD files which MLCAD doesn't like.

Today's xkcd was LEGO-centric. Don't forget to hover over the image to read the alt tag (although I susect many people here already knew the relevant tire fact).

If you aren't an xkcd fan, I feel it's important to point out that it is occasionally not safe for work. I'd say 99% of the comics are fine, but a few aren't.

I've imported some heightfield data using stl2dat and want to know how to create edge lines (using LDDP presumably). I want every triangle edge to have a line so that I can orientate my models around the terrain better. Thanks.

LDView locked up my computer three times in a row when viewing the attached model. I had to reboot each time. This only started happening today.

Maybe my video card is dying. I'm going to try blowing the dust out of my case.

I got an error in SR 3D Builder that is a bit mysterious to me. It says:

Found 1 parts duplicated in the model file. These parts need to be removed to load selected model. Proceed?

My problem with it is that it provides little feedback. Which part is being removed? Which is the other part? Why can't it continue?

This is very vague.

[edit]

Also, the model I am working on (Datsville) has 170,000 parts. I do not want to click through every one of these errors.
