Moving a .stl File

clktp · February 5, 2016, 04:37

Hello,

I have a stl file but I need to change its position. I know I can scale or rotate it by using surfaceTransformPoints but I couldn't find a way to move it. Is it possible to do it without a CAD program by an OF utility, a script or something like that?

Regards,

surfaceTransformPoints does seem to have a translate feature. Did you try it?

Honestly I couldn't use it if it's used for moving it.

for example I used this script and nothing changed.

#!/bin/bash
export FILE="first.stl"
surfaceTransformPoints -translate "(1 1 300)" $FILE
surfaceTransformPoints -rollPitchYaw "(0 0 0 )" $FILE second.stl

I just tried it and it works. If you properly included your script here it doesn't work because you made a mistake in the command. If not, perhaps the version of the utility you are using is too old.

Yeah it worked, thanks. The reason why it didn't work at the first time is that I didn't write the output file, at least I guess so.

It works like this. It moves the geometry 300 meters in z direction.

#!/bin/bash
export FILE="first.stl"
surfaceTransformPoints -translate "(0 0 300)" $FILE second.stl
