To accurately measure in Blender, while in edit mode go to the overlay menu in the top right corner. Set the scene to scaling of 100 in Blender, Select the object and also set the export FBX option scale to 100 as well. Worked: before 2.73, Short description of error I have to agree with Bastien after some thought. When opened in Cura it needed no scaling. Also, when you export to STL, scale is not included. Again (and again, and again), there is no way to get an automatic correct behavior in all cases, due to STL files not conveying any scale info. Step 5: Insert>Features>Scale Step 6: measurements before scale Step 7: measurements after scale Posted on September 13, 2016 by Angus. for our printer. All the STL files I have downloaded from the Internet have been to the correct scale so I assume other applications have been able to get a more user friendly output. To make a good platform to print on, we are going to squash one side of the meshed model we created in the previous page.. First, open Blender and delete the default box by pressing [Delete].. Since you expect your STL to be in millimeters, this was working "by chance". Win 7, 8, Mac OS X (not related to system), Blender Version Doing the happy dance. The button says "use scene scaling", but in fact it always uses the standard scaling of 1? If you want an STL file with (implied) units as millimeters, then you have to set global export scale accordingly (1000). Here you can find Scale 3D models ready for 3D printing. A friend of mine gave me some STL files of something he would like me to print. I don't know the original intention of the feature so I will leave to Bastien, but reopening. Well, answer is in the question I believe? It is easiest to not set any scales in Blender. Also pressing to align the viewport zoom to everything does not help, because the camera clipping is too small. Scaling an STL in FreeCAD. To raise an old topic but I had the same experience this weekend. Why is there a button to use scene scaling when it has no influence on the export on what 1 BU is?? If it’s 1 by default, but can be set to 1000 so it can output the STL file (Which is unit agnostic by design) in whatever scale is required. How can that be correct behaviour? Custom scaling for imported STL One workflow item I seem to be doing quite often for 3D printing (or at least want to do is): Find some model I like on thingiverse or similar (or I may make my own in Blender or similar) Solved: Hi! I might see if my Python skills are up to suggesting a patch. It would be really great if the 3D Print tools Add-In that ships with Blender (Since 2.6 ish I think) had an arbitrary scaling factor. Looks like reporter expects that the setting in the scene is the setting blender exports at but that is not how it usually works with exporters, rather we make sure to export at the base unit (which is meter), so scaling is correct. Not too long ago Blender units were exactly as STL units... Not directly related to 'real world' units at all... Until the scene unit settings were added (and cycles makes some assumptions too I think). Taking a 3d model from 100% to 75% or even upscaling to 125%? Any workarounds? Did you ever need to scale your object in multiple dimensions and export it to an external format, like .stl ? Take the starting cube and change it to be 10 x 35 x 25 and you will get an STL file with those exact dimensions in mm. I have already explained why and how it works in length, this site is not a forum, period. I found a new way to scale STLs in FreeCAD where you don’t need to use the Python console. Solved. Just assume that this is mm and you are good to go. Also when I exported the file using Blender "3D Printing" module with the option "Apply scene scale settings on export" disabled the size was fine. You are obviously not Wirkung with it! I will take a look at this tip. Setting the scene scale before adding/importing an object (for example an .obj File) or afterwards, enabling the "Use Scene Scaling" option and disabling. Thanks everyone for the assistance! As explained, previously this worked by accident mostly. Select File > Import > STL and find the STL file you just saved.. With your file selected, click Import STL.. Now you should see your meshed object. Lithophane Using Blender: This is NOT an Instructable on how to create a lithophane using Blender from scratch, it is simply instructions on how use the .blend file found in this Instructable to create your own lithophane.I am assuming you have some basic Blender skills to b… Go to the Part Workbench. If it’s 1 by default, but can be set to 1000 so it can output the STL file (Which is unit agnostic by design) in whatever scale is required. But if I use any other scaling it get's wrong with or without button on. It is free to download for Mac, PC or Linux. User has to define itself which unit he wants his STL to be in, and set scaling accordingly. I just have it set to "metric" as I assumed RH would be able to figure it out in those terms. When I exported the file using Blender 2.8 "File/Export/STL" the size was fine. I tried to export and import stl and to me nothing seems changed... 1 blender unit is still exported as 1 stl unit (irrelevant of the scene scale setting) so it's unclear what this patch did... Is there documentation about it? That way regardless of what the STL format does or does not include, end users can set a scale that works for their models and their 3D printer without having to fiddle with the manual export settings (which are not reflected in the extra 3D Printing tools which also has an export button!). System Information In object mode, you select your object, hit “ctrl+a” and select scale. I changed the value of “Unit Scale” and the exportation works. When I open them in Cura, they are extremely small (like 1.3mm) and should be much bigger. Because of the extensive use of OpenGL (and some rather old versions of it), Blender often uses parts of the library that other programs may never touch. To the reporter: are you using the new option in the exporter to use the scene's unit? Does anyone have any recommendations on a good way to scale a .stl file? Import the STL into any other program (not Blender) (I'm using PrusaSlicer for 3d printing), and notice it is at 1/1000th the scale. Step 4: To import diag. I don't know how to export in MM from blender. How to measure in Blender? Cura is the software that allows us to prep the .stl files for our 3D printer (Ultimaker2). I filed a same bug but it was never looked at like this here. Probably caused by https://developer.blender.org/rBAe6b174a3b618907ed189c1fe95df7c9b19fc62ca I know that 1 Unreal Unit is 1cm, but in blender how would you make it to where in Blender 1 BU is 1cm.
