Model not generated - Githubissues

BenRoe commented 5 years ago

Hello, i am a openscad newbie. If i open the DES_ChocChordCaps.scadfile, i get a lot of warnings and the model is not generated. I installed this scad-utils libraries.

You will also need to install comprehension-demo. and move around some files to corresponding folders.

Added the mention scad files to my library folder ‎⁨HDD⁩ ▸ ⁨Benutzer⁩ ▸ ⁨Ben⁩ ▸ ⁨Documents⁩ ▸ ⁨OpenSCAD⁩ ▸ libraries

Changed the library path in the code:

use <morphology.scad> //for cheaper minwoski 
use <transformations.scad>
use <shapes.scad>
use <trajectory.scad>
use <trajectory_path.scad>
use <sweep.scad>
use <skin.scad>

and get this error. ERROR: Recursion detected calling function 'len' in file skin.scad, line 59

Are you still getting WARNING: Ignoring unknown function 'to_3d', in file skin.scad, line 11? Recursion failure reproducible by incorrectly defining path call in skin.scad: use <scad-utils/transformations.scad>. You can move the library or fix the call at skin.scad.

This is my fault for keeping disorderly lib path. I'll fix it comes next push thereby breaking things for the rest of user. Sorry.

Thanks, i have similar problems. I am new to scad. The error I get is: ERROR: Recursion detected calling function 'len' in file skin.scad, line 59 I also get a fairly large number of warnings in the console. I believe i have the path correct to the transformations library.

Forgive my ignorance, but is there an alternative format that could be exported to?

pseudoku commented 4 years ago

Added the library.zip in the repository, please give it try and see if that fixes the issue and let me know if error continues to persist. Thank you.

The problem still persists for me, with either the provided libraries.zip or downloading the head version of scad-utils on OpenSCAD 2021.01 I get lots of errors:

@uqs @BenRoe @kelsh Did you ever figure out how to fix this? I'm also getting >200 warnings, all related to trajectory.scad.

allymparker commented 3 months ago

Anyone wanting to solve this problem either needs to:

Download the latest version of scad-utils from the openscad repo rather than using the zip in this repo, or;
Download a 2019 version of OpenSCAD from https://files.openscad.org/
