Dear friends

I never had such a strong learning curve with OpenScad. It is 100% the tool
I looked ever.. I can do all my drafts and ideas in a very short time.

The only thing I miss is MEASSUREMENTs.

As far I could found out there is no convenient way to add meassurement to
my constructions

So I guess there should be an easy was to export my construction and import
it in LibreCad or Freecad (I'm using Mint).

I don't need a detailed explanation but the raw steps would be great.

Many Thanks
Karl

P.S.
As I focused in trhe beginning I have no CAD experience. I'm coming from
programming

I export the file as an STL file and then open it with 3d-Tool Free Viewer it has an excellent measuring capability.

FreeCAD has a measurement tool; you can import the STL(s) into FreeCAD and
use that:

Apparently FreeCAD has an OpenSCAD workbench which allows you to do some
OpenSCAD things within FreeCAD.

Truly measuring from one point to another on a model is close to
impossible, because of the structure of the language.  Modules are black
holes; you can't get any information out of them.

However, here's a measuring stick that you can drop into your model.  If
you position it so that it lines up with the two points, you can read
off the dimension.

It doesn't have any actual numeric markings; instead, it has black marks
every once in a while that you can count.  You can set the interval, or
it'll automatically pick a power-of-ten interval based on how far away
the camera is at refresh.  Adding numbers wouldn't be too hard.  Note
that it's only visible if you set $measure true.

module measuringstick(len, interval=pow(10,floor(log($vpd)-1)), center=false) {
if (!is_undef($measure) && $measure) {
r = 0.5;
mark = interval * 0.01;
%translate([0, 0, center ? -len/2 : 0]) {
for (z=[0:interval:len]) {
mark1 = min(len-z, mark/2);
if (mark1 > 0) {
translate([0,0,z]) color("black") cylinder(r=r, h=mark/2);
}
z2 = z + mark1;
block = min(len-z2, interval-mark);
if (block > 0) {
translate([0,0,z2]) cylinder(r=r, h=block);
}
z3 = z2 + block;
mark2 = min(len-z3, mark/2);
if (mark2 > 0) {
translate([0,0,z3]) color("black") cylinder(r=r, h=mark/2);
}
}
}
}
}

//$measure=true;
rotate([10,0,0]) measuringstick(100);
