Problem with "Difference" and F5 ... (from Empathy)
Dave,
I saw your post on the Empathy site. Not sure you realise that's rarely viewed
by those on the Mailing List, so I'll copy its content in this post.
I'm no expert but FWIW I tried your file with the free repair tool at
https://www.formware.co/onlinestlrepair
and got a rather unhelpful message that won't please you:
"Sorry, this file was not fixable: Error reading your file."
====================
Problem with "Difference" and F5 ...
Hi, I am running Openscad v2021.01 and am having problems with the following
script.
$fn=32;
difference()
{
union(){
import("base_slide_heavy_duty_HA.stl", 4);
hull(){
translate([22,-13,0]) color("red") cube([20,70,3]);
translate([35.5,-13,0]) color("green") cylinder(h=3, d=13);
translate([28.5,-19.5,0]) color("blue") cube([7,5,3]);
translate([24,57,0]) color("green")cylinder(h=3, d=4);
translate([40,57,0]) color("green")cylinder(h=3, d=4);
}
}
translate([25.8,-17,-1]) color("red")cylinder(h=5, d=3);
}
and when I hit F5 I get the following display
i.e. there are "holes" in the render.
If I comment out the difference() it appears correctly except the red cylinder
isn't subtracted :-
The "imported" .STL file is attached.
This is only a problem for the preview, the generated STL is fine.
What am I doing wrong ??
Regards,
Dave

stl file is not attached.
I have found that doing boolean operations on stls is a little tricky.
Many times it fails, complaining that the mesh is not closed.

Similar.
Does anyone have a good workflow to ensure that your meshes are closed
before importing into OpenSCAD?
I was thinking yesterday about writing a script that calls MeshLab to
convert an STL into an OBJ, and then calls it again to convert back into an
STL, possibly unifying/dissolving points that were really close together.
And using this script to prep any models before importing them.
Thus Sanjeev Prabhakar hast written on Sat, Feb 19, 2022 at 10:54:21PM +0530, and, according to prophecy, it shall come to pass that:
stl file is not attached.

I didn't send it to the "Empathy" site (whatever that is).

Odd. I didn't see your initial 4.09 pm post in my Agent email inbox, and still
don't. Nor in my Gmail web inbox. Hence my post.
But it clearly did get to the list as I see it quoted in replies from both
Adrian and Ray!

Sadly, none of the suggestions achieve what I need :-(
I tried downloading the latest x64 dev snapshot and it failed with :-
... so, going back to the last stable.
I am running under Win 7 x64 Pro with 8G of memory. The fact that the output STL file is OK wont stop me proceeding but the lack of a reliable preview is very irritating.

Terry, if it is on Empathy it was sent to the list, Empathy looks at the list.
Mailing-lists are very simple beasts, they either fail big or work.
You have and unconventional email setup and use, you should assume problems are at your end.
Also Empathy is a secondary capability with a number of presentation bugs, it should be avoided
unless your email is down and something is critical, but even then...

Thanks Michael. I use Empathy only to confirm my post has reached the list. As you know from our earlier discussions, I don’t see that in the list inbox. Despite its serious flaws I also find Empathy’s compact display quite attractive.
On this occasion Dave’s post was displayed in Empathy but (illogically) in neither my reliable Agent email app or in my browser Gmail. I thought I was therfore being helpful by making its content accessible. But in future I’ll make the assumption you suggest ;-)
