So incredibly helpful, I've watched this 10-20 times over the last few years.

I was having sizing issues when I was slicing models for printing but this has solved it. I now have 1 to 1 scale thanks to you!

[hankokrob]

One of the best courses blender ever .

[atefe]

Thank's ! That's done, this tutorial is very useful for me

[indrajitdas]

Sir, coming to your channel gave me the experience as if I dived into a lake to reach its bottom but eventually reached the bottom of a sea. Thank you sir its a great learning experience.

[TechSquidTV]

Ahh saving the startup file feels amazing. I wish it let us use multiple profiles. But I saved a template file as well just in case. Thank you!

I went through your entire series when I started 3D printing a year and a half ago. It was extremely helpful in getting started. I am now working on more precise parts and am finding an issue that I can't seem to remedy myself.

To explain the issue in terms of a simple part, I have sketched a cylinder in Blender. Exterior (X/Y) diameter of 20mm. Interior (X/Y Boolean) diameter of 8mm. Length (Z) dimension of 20mm. I exported this as an .STL. Opened in Cura without scaling and sliced. This is moved to my CR-10S Pro and printed in PETG, which housed in a filament dryer. The final print measures true for Z but the Exterior diameter is 19.74mm and Interior diameter is 7.4mm.

Setup:
Blender 3.4.1
Ultimaker Cura 5.2.1
Creality CR-10S Pro





Any help would be greatly appreciate and thanks again for the assistance in my early stages!

Might be appropriate to insert a short discussion about what might happen to camera clipping planes, especially when zooming into small objects. Can be frustrating, but easy to fix if the user knows how.

Thank's ! That's done, this tutorial is very useful for me, I live in Belgium, and indeed it is difficult for me to work with inch sizes.
There are good tutorials everywhere, but I hadn't found this one yet ;-) because cad programs are very expensive, I'm going to try it with blender!
It's quite an adjustment for me, but now that I'm retired I have plenty of time to learn it.
Thank you!

amazing, im a beginner and must say that your video solved so much boiling frustration. for christ sake, no one measure in meters, even if we are using the metric system!. also the constant deleting of the cube, camera and lighting was driving me mad. those things should be stuff that you can turn on if you want to, not be there by default!!
thanks man, you saved my day.

[mdlabibsikder]

You are awesome
Your videos is so helpfull

[TheChartle]

Thanks! Looking forward to the keyboard shortcuts Sheet :)

Great Video, great help. Thanks a lot

[kursorgildas]

thank you for making this video, so helpful for beginner like me...

[MattFromAmerica]

Thank you for the video! Second time around, but I cannot recall how to bring the grid back so it's not gone.

[sierralarars]

Permanently deleting the default cube seems like some sort of blasphemy haha! Thanks for the very quick and to the point tutorial!

[Jimbo-in-Thailand]

Excellent! So if changing to inches do we also have to set Unit Scale = 1/12 since selecting Imperial defaults to feet? I R confused that we would have to change anything once we select which units to use. Thanks!

[nocakenocode]

hmm....you could use a brighter shirt or jacket to separate yourself from the background as you're blending in with the dark side, some dim warm color light from the right and maybe a blue led light bar in the back...with a lavender pot or some vegetation/decepticons.

Other than that great video, just what I was looking for, much obliged.

[auneakeffect]

the MM units arent saving. Am I missing something or do we have to set this up every time we load up a new project in Blender?
