To long to compile... How can we abort a compilation?
Hi,
Geetings from Portugal. This is my first post to this forum.
Can anyone explain how the simple code that follows takes so long to compile
(about half-an-hour).
In addition the OpenSCAD editor stays locked, and the only way to abort the
compilation I found is to
kill the Windows process.
The code:
/minkowski(){
difference(){
translate([0,0,20])cylinder(r=DCarrier/2+RSphere,h=1,center=true);
translate([0,0,20])cylinder(r=DCarrier/2,h=1+delta,center=true);
}
sphere(r=RSphere);
}/
It would be nice to have the possibility to terminate the compilation at
will, if we feel that something went wrong.
Kind regards.

There's a red circle with an X at the far bottom right of the screen.. try
clicking it.

I can't see any red circle with an X in the Windows openSCAD port . Maybe in
the Linux port ...
I'm using openSCAD 2015_03-1.
Thanks anyway.
Regards.

On win 7 the cancel is in the very lower right hand corner.
But your code is not responsive for me as well.
To get some results, you should decrease the number of facets by a lot (use
$fn for that)
Later for the final render/compile you can increase it again.
This code renders in 1min6sec
and compiles in 1min8sec (on a 1GHz netbook)
fn_sphere=8;
fn_cylinder=16;
RSphere=2;
DCarrier=10;
delta=2;
minkowski(){
difference(){
translate([0,0,20])cylinder(r=DCarrier/2+RSphere,h=1,center=true,$fn=fn_cylinder);
translate([0,0,20])cylinder(r=DCarrier/2,h=1+delta,center=true,$fn=fn_cylinder);
}
sphere(r=RSphere,$fn=fn_sphere);
}

a. Like this (for F6 Render). That's Windows 7/64.

b.
With the variables I used, 25/3/0.01, Compile (F5) took 38s, the GUI did
lock-up, that needs looking into. Usually it doesn't take long, and doesn't
lock-up. Given minkowski is intense, perhaps it needs a event process or two
in the loops??
Render (F6) was instant.
What size was causing your looong compile?

Hi jpmendes,
Your way to do it is complicated and VERY slow.
Try the code below for similar result much faster:
fn_sphere=360;
fn_cylinder=360;
RSphere=2;
DCarrier=10;
delta=2;
translate([0,0,20])
rotate_extrude($fn=fn_cylinder)
translate([DCarrier/2,0,0]) rotate([0,0,90])
minkowski(){
square(delta,center=true);
circle(r=RSphere,$fn=fn_sphere); }
Good luck with OpenSCAD, it is my favorite 3D CAD tool

Thanks for your help. I want to thank also all the guys who posted useful
suggestions. Yes the code I wrote was not very efficient, I was then
starting with openSCAD. Now I'm a little more confident.
However when I wrote that I couldn't see the red button I meant the "F5" CSG
tree compilation not the "F6" rendering. At CGAL rendering time the editor
is not blocked. So I still find useful to have a possibility to stop the
GSG tree compilation at will. One example is, to try several types of code
and to chose the one more efficient without having to wait lots of time.
Also the editor should be independent of the compilation processes to
maintain the responsiveness. I would like to have the possibility to be
compiling one module and to be working on the code of another module
simultaneously. The compilation could be done over an automatically
generated backup copy of the actual file.
Yes I know I have to buy another PC, my dual core AMD 64 Athlon is now 10
years old. :)
Thanks allot.
Kind regards.
