Rhino convert obj to stl free#
We recommend uploading your SketchUp file into Meshmixer (a free program from Autodesk) to check your file for faceting and fix any surface flaws. Tip: SketchUp isn’t inherently built for model production therefore it’s useful to check your SketchUp file for additional feature accuracies once it’s exported from the interface.

If your CAD software is not listed below or if you require additional assistance, please contact your CAD software technical support for information about exporting to an STL. The following step-by-step instructions for converting CAD files to STL came from each CAD software company’s website or from 3D printing and design user forums it’s an overall simplified step-by-step process from the greater 3D printing community. We’ve compiled tips on exporting for the best “surface: file” size ratio below. These are the parameters that affect the faceting of the STL. When exporting to STL in your CAD package, you may see parameters for chord height, deviation, angle tolerance, poly count, or something similar. 3D printing can only accept a certain file size therefore it’s important to find a balance between your model, its desired surface, and the 3D printing process of your choice. However, the smoother/ less faceted your surface is, (the higher the poly count or triangulation) the larger your file.

If the STL is coarse and faceted the physical 3D printed model will be coarse and faceted as well. You cannot build the model smoother than the STL file. The parameters used for outputting a STL will affect how much faceting occurs (Figures 2 and 3). The triangulation (or poly count) of a surface will cause faceting of the 3D model. STL is a triangulated representation of a 3D CAD model (Figure 1). I use this at times and it’s really nice to be able to copy and paste between apps like PowerCADD and formZ.STL is the standard file type used by most additive manufacturing systems. Do a quick Google search for “OpenClip” and “WildTools” to see what I mean. If younger developers would pull their heads out of their butts and put simple 3D geometry on the clipboard in a useful basic format, then moving data between apps would be far simpler than it is today using intermediate files… I feel like I’ve gone back in time 20 years having to save, name, open and delete intermediate files. Sometimes, these older formats are far better that the new ones because you don’t always want all the cruft that comes along with the native formats. For accurate geometry that just needs to be transferred as trimmed planes in Rhino, it’s awesome. Oddly, it’s worst with the native SU formats, but OBJ is simple and has been around so long that it’s extremely well supported. Rhino is really hit-and-miss with grouping hierarchy, so it doesn’t always honor the hierarchy of groups and components from SU.

PITA when I only want the certain geometries transferred to another app to do something that SU can’t accomplish. And my transfers to another app usually require the coordinate systems to be the same, so with copy & paste I also have to make sure I either create something at the origin for reference, or use paste-in-place to keep the subset in the correct location.

Saving in the SKP format doesn’t let me choose a selection or subset of a much bigger model, so I have to copy and paste to a new file and then save that.
Rhino convert obj to stl mac#
Most other apps don’t support the most current SU version file format so until SU 2021, the Mac version didn’t have version selection when using “Save a copy as…” So getting the whole model exported to an older format that was supported by another app was risky because you could accidentally save your current file as an older version, losing whatever differences there are between formats. Maintaining group/component hierarchy is really important, and so is extracting part of a much bigger model for use elsewhere…
