If you go to the Scene tab in the Properties Editor, select Millimeters as the preset and make sure Unit Scale is set to 0.001000, you can leave the Scale to 1.00 while exporting and the STL will have the correct dimensions.
Hi there, I've just imported an STL file from CATIA..... HOW ON EARTH DO YOU USE THIS BLENDER PROGRAM.... CATIA is intuitive but it looks like this blender program needs to come with instructions :/
Blender is used for things that are incredibly arbitrary, or do not need precision. It's used to make art. It can directly, efficiently, and rapidly alter mesh bodies. It can mimic photorealistic lighting and materials. It can make particle effects and render entire movies. It is a suite of tools that can do significantly more things than most parametric software can (at the cost of the precision mentioned before). If you're using it to mess with .stl files, you're truly opening a can with a chef knife, instead of the very specific, measured accuracy and guidelines of parametric software. It can be done, but you're generally making your life more difficult. That said, there *are* instructions on how to use Blender: incredibly in-depth documentation, and countless videos by both the creators and users of it. - User of Fusion 360 (2+ years) and Blender (3+ years)
@@Rendat666 do you recommend a different program for people who are new to 3d modeling and printing? Preferably one that is also free. I tried tinkercad but I couldn't import my stl files to it and prefer the fact that blender is an installed program instead of a web service.
@@umungus518 I'd recommend looking into Fusion 360 by Autodesk if your intention is to use the models for printing. You can get a hobbyist (or something named similarly) license for free, and there are few limitations to what you can do with it. It's fairly elegant, features numerous tools for assembling your models, and is more readily used by 3d printers. The downsides include some wonkiness with splines and refusal to carry out certain commands if it would create bodies with errors (like parts inside of other parts, unrealistic geometry, etc). There's always a way around those though, and plenty of documentation and RUclips videos on how to use it.
I'm amazed! Would the workflow have been similar if the holes had been circular? I'm thinking a circular hole would, in an STL, be compromised of multiple faces and not truly circular?
Yes, tris to quads only converts to quads where possible. There are certain conditions in meshes where a tri can't be converted to a quad and those tri's are skipped by the operation. You're mesh will still be fine for output to STL if it contains tri's.
sorry, but what you presented is usually not the problem when dealing with cad/stl files. while method works, you are essentially using a knife for a screwdriver. yes, it works, but that is not the proper usage and there are better ways.

2:41 Tri to quads, exactly what I needed! Thanks!
The slicer setting for over-filled holes is "horizontal expansion" in Cura. Set it to a negative value and it'll give more hole clearance
Thanks for the tip Matthew, much appreciated.

Hi Martin! Yes same process, as long as the circles are quads the loop tool will find the loops.
Actually I selected based on normal direction so they could also be circles made of triangles and it would still work.
Martin Karlsson yep, just the same.
tris to quads didn't, i still got triangles, any tip?

Hi. I have a stl shotgun wad file wich is only 3/4 of a whole wad,how can i make it to be a whole wad?
Add another 1/4?

Very Helpful Thank-you
Thanks Wally!
