Split in 2, scale the piece you want and re-add the other half is probably the best way. in 123d I would fill in the hole with the merge union (with a cylinder object), scale it, and either keep it unfilled and drill it, or do a subtraction union on where you want the holes. measure the object with 3D View: Measure Panel add-ons it is 100 m sized. Reducing the number of triangles will reduce the smoothness of the surfaces, but also the file size. I tried downloading it in a 3D designer program but the files on thingiverse all download as a cura file. I know Unity Gossip gets more traffic, but please post these questions to the right place. This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. The elements in the container are never "invalidated." Most of them will edit the stl's as well.Take the time to learn one. I ended up diving into Tinkercad, measuring everything and designing something similar (see, https://3dprinting.stackexchange.com/questions/1334/what-is-the-easiest-way-to-modify-resize-an-object-inside-a-stl-file/1335#1335, https://3dprinting.stackexchange.com/questions/1334/what-is-the-easiest-way-to-modify-resize-an-object-inside-a-stl-file/1341#1341, https://3dprinting.stackexchange.com/questions/1334/what-is-the-easiest-way-to-modify-resize-an-object-inside-a-stl-file/8143#8143, https://3dprinting.stackexchange.com/questions/1334/what-is-the-easiest-way-to-modify-resize-an-object-inside-a-stl-file/1349#1349, https://3dprinting.stackexchange.com/questions/1334/what-is-the-easiest-way-to-modify-resize-an-object-inside-a-stl-file/8147#8147, https://3dprinting.stackexchange.com/questions/1334/what-is-the-easiest-way-to-modify-resize-an-object-inside-a-stl-file/15245#15245, Hi welcome to 3DPrinting.SE! SubaruB4RSK - in reply to ... You can't click on the circle and resize because of the fact that the object isn't a FreeCAD model (it's a STEP file). Try to take models not larger than 30k triangles. FWIW, I would probably break this into three STLs using a DIFFERENCE method, stretch the outer ones using a SCALE method, then use a UNION to put them back together. https://www.tinkercad.com/, Click here to upload your image The one problem that I've had with OpenSCAD is that it will frequently crash unexpectedly or run incredibly slowly when dealing with an STL with a large number of triangles.

Cura is the software that allows us to prep the .stl files for our 3D printer (Ultimaker2). These programs typically allow you to set the quality of the .STL file in one way or another. The perfect solution for me would be to just import it in Tinkercad and then modify it however I have no idea what the steps are. When exporting a file with a tolerance larger than 0.01 mm, triangles might become visible in the 3D print. Press Esc to cancel. In practice, however, 3D files need to be shared or uploaded – and that’s where overly heavy 3D files can be a pain. Model available for download in # format Visit CGTrader and browse more than 500K 3D models, including 3D print and real-time assets It looks as follows. It has excellent selection tools, you can undo/redo selection and obviously you can resize any portion without affecting the others. Additionally the angle of the upper surface must stay the same. Press “s” to scale. The STL format provides no information about the units or scale so MeshCAM has to rely on you clicking “Inch” or “MM” when you load the file. OpenSCAD, as mentioned above, is pretty well established as an open source tool for modifying STLs; however you have to be comfortable writing programmatic CAD instead of using GUI tools. These are percentages … Blender Artists is an online creative forum that is dedicated to the growth and education of the 3D software Blender. 2. Looking for answers?

Blender can reduce the triangle count, but the more you have to take away, the worse it will end up looking. I am able to open it in 3D Builder, but I am unable to see the model when I import it in Blender. I think what you are trying to do is somewhat non-trivial so whatever tool you choose there will be some learning curve. For Blender the base unit is Blender Units = meters, so the object came in as roughly 36 x … Some are made with mesh modelling tools like Blender, Mesh lab, Art of illusion, Wings, Z brush, etc, etc, etc. 3D modeling tools for STL for reducing vertice count, converting gcode, simplifying meshes and other 3d printing tools. Unfortunately, there is no simple method for modifying specific features of an STL. This is the reason that the overall dimensions are show when a file is being opened- so that you have some way to confirm that the overall scale is correct. Joined: Oct 30, 2005 Posts: 5,325. Exporting with a tolerance smaller than 0.01 mm does not make sense because 3D printers cannot print this level of detail. (again with a cylinder). What is the easiest way to modify/resize an object inside a STL file? say no or yes, same process as is for import of IGES/STEP. If you resize the container to be smaller than its current size, any extra elements beyond the new size are destroyed. In this case, take your high-detail size-heavy 3D file and continue editing it in another program. ;) 15 Comments . I can see that the part is imported, it's called Part21, but all I see is a local coordinate system. ... enlarge it at the border to the toolbar above - just like you resize a regular Windows window. We can also scale the individual size of selected objects instead of scaling the distance between object along with the scaling of the objects themselves.
