moehriegitt / hob3l Goto Github PK

Hi. I'm building on Windows 10 using MinGW. Impossible to get fontgen to compile. Result from "make" in font directory is:

Thanks for helping out.

Best,

Franck

mv libhob3lbase.a.new.a libhob3lbase.a
process_begin: CreateProcess(NULL, move libhob3lbase.a.new.a libhob3lbase.a, ...) failed.
make (e=2): Le fichier spécifié est introuvable.
make[1]: *** [libhob3lbase.a] Erreur 2
make[1]: quittant le répertoire « D:/projects/hob3l-master »
make: *** [all] Erreur 2

At the current tip of master, 5611971, I get this:

$ build font
...
./fontgen.exe

At 5611971 (the current tip of master), this file provokes an assertion error: hob3l.exe: src/csg2-bool.c:671: chain_flush_vertex: Assertion ((c->vert.size & 1) == 0) && "Odd number of edges meet in one point"' failed.`

I was wondering if you're planning to support more complex operations sometime in the future? I'm excited about using hob3l, but my projects make heavy use of hull (eg. for constructing rounded cubes from 8 spheres). I have no idea how difficult that would be to implement, though.

Trying to slice on macOS makes hob3l exit with sig 11:

Example file is here

> out/bin/hob3l.x myfile.scad -o myfile.stl
Info: Z: min=0.1, step=0.2, layer_cnt=152, max=30.3, grid=2^13
Segmentation fault: 11

Hello,

I was able to finally build hobl3l on Windows. Tried hob3l with one of my SCAD file. Hob3l cannot generate an STL with following error (whereas it is working just great in OpenSCAD).

$ ./hob3l.exe d:/tmp/test.scad -o d:/tmp/test.stl
d:/tmp/test.scad:6:7: Error: Expected '(', found '='.
Unexpected token, found '='.
pi=3.1415926535897932384626433832795028841971693993751058209;
^
Here is an extract of the SCAD file:

//WELCOMEATS3DKEY
//include <newdata.txt>

/////////////////WRITE
//Write
pi=3.1415926535897932384626433832795028841971693993751058209;
pi2=pi*2;

//default settings
center=false;
h = 4; //mm letter height
t = 1; //mm letter thickness
space =1; //extra space between characters in (character widths)
rotate=0; // text rotation (clockwise)
font = "D:/projects/keymanager_new/bin/profiles/letters.dxf"; //default for aditional fonts

module write(word){

rotate(rotate,[0,0,-1]){
for (r = [0:len(word)]){ // count off each character
// if the letter is lower case, add an underscore to the end for file lookup
if ((word[r] == "a" ) || (word[r]== "b") || (word[r]== "c")
|| (word[r]== "d") || (word[r]== "e") || (word[r]== "f")
|| (word[r]== "g") || (word[r]== "h") || (word[r]== "i")
|| (word[r]== "j") || (word[r]== "k") || (word[r]== "l")

|| (word[r]== "p") || (word[r]== "q") || (word[r]== "r")
|| (word[r]== "s") || (word[r]== "t") || (word[r]== "u")
|| (word[r]== "v") || (word[r]== "w") || (word[r]== "x")
|| (word[r]== "y" )|| (word[r]== "z")){
if (center == true) {
translate([0,-h/2,0]){
scale([.125h,.125h,t]){
translate([ (-len(word)5.5space/2) + (r5.5space),0,0])
linear_extrude(height=1,convexity=10,center=true){
import(file = font,layer=str(word[r],"_"));
}

I would like to point out that identifiers like “__CP_CSG2_TRIANGLE_H” and “__cp_ring_replace” do not fit to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?

Hello, please can you provide a precompiled version of hob3l for mac. I’m not able to compile it. Of course I can pay for this. Thanks in advance

Would you like to add more error handling for return values from functions like the following?

• cp_printf ⇒ cp_ps_doc_begin
• fclose ⇒ main

Add this bug as a reproducible thing in case someone in the future works on hob3l, because it's awesome, and waiting for CGAL is painful sometimes :-)

shaft.scad:

`include <threads.scad>

// 54 threads
// length 3.5 inches
// outer diameter 1 inch

// about 2 threads missing from top and bottom so 56 threads over 3.5 inches = 16 threads / inch

inch_in_mm = 25.4;

difference() {
english_thread(1 * 26.5 / 25.1, 16, 4);
//cylinder(100, d=20);
english_thread(0.8,16,1,internal=true);
translate([0,0,inch_in_mm]) {
//cylinder(4*inch_in_mm,d=22);
}
}`

Uses threads library from here: https://www.dkprojects.net/openscad-threads/

Create csg:

$ openscad shaft.scad -o shaft.csg ECHO: "mm_diameter: 26.8167" ECHO: "mm_pitch: 1.5875" ECHO: "mm_length: 101.6" ECHO: "mm_diameter: 20.32" ECHO: "mm_pitch: 1.5875" ECHO: "mm_length: 25.4"

Run hob3l:

$ ./hob3l.exe shaft.csg -o shaft.stl Info: Z: min=0.1, step=0.2, layer_cnt=508, max=101.5 hob3l.exe: src/csg2-bool.c:705: chain_flush_vertex: Assertion ((c->vert.size & 1) == 0) && "Odd number of edges meet in one point"' failed.
