The model above is mostly symmetrical, so removing 1/2 or even 3/4 of it is an easy way to reduce the triangle count. And, trimming away unneeded portions of the model. The two main ways to do this are decimation in a mesh editing tool before importing to SOLIDWORKS. If you notice your SOLIDWORKS performance come to a grinding halt at this point, there are some options which can make things a little better: Tools like Convert Entities, or Intersection curve help extract data to form 2D sketches.ģD features can make use of Up To Surface,Next, Vertex, and Face options.īelow is the imported STL file in SOLIDWORKS: Having the STL model imported into SOLIDWORKS allows some shortcuts to be taken when remodeling: This Gripper model was recently posted in the Questions section with the desire to turn it into a SOLIDWORKS model: Maybe there will be in the future? Until then, you'll need to remodel the 3D model.
CONVERT OBJ TO STL ONLINE SOFTWARE
There is no magic button or software which converts mesh models into perfect CAD models. They won't be tricked by you importing, then saving an STL file as a Step model.
If you want a part machined, the machinist will prefer/need a non-faceted 3D model.Saving a mesh as another file format maintains a large file size. Mesh models often have large file sizes.Saving a mesh model as a SOLIDWORKS part (or other file format (step, iges.etc)) does not magically remove the thousands of triangles which make up the mesh.If your model is too large, try importing it with a different unit, or scale the STL file in your favorite mesh editor. SOLIDWORKS has a limit on the size of model it can display It was 1 kilometer years ago, it may be more now.If you have too many faces/facets, try decimating the model in your favorite mesh editor. SOLIDWORKS has a limit on the number of facets it can open/display.More triangles = finer resolution = larger file size.STL files are made up of thousands of tiny triangles.A hole in an STL model is not a circle, it is a polygon.STL files are a rough approximation of a surface.Here are some things to consider before stopping at this point: You could be done at this step if your goal is saving a piece of garbage. "Save as a sldprt file" they advise, and you are done. Sadly, this is where the other tutorials end.
I've used it at work a few times, and prefer to edit scan data in Geomagics Design X, or Geomagic Control. The ScanTo3D Add-In is most useful when working with scan data, but give it a try if you have it. It allows for more advanced importing and repairing of mesh models: IF you have a version of SOLIDWORKS with the ScanTo3D Add-In, consider turning it on. If you know what units the mesh model was exported with, set the units in this SOLIDWORKS dialog box to match. Graphics Body is often the default, and it is mostly useless unless the desire is simply viewing the mesh model. You'll usually want to set the Import As option to Solid Body. Or enter a loop where each fix causes previously repaired errors to return. relying on "autofix" will often make the model worse. Repairing errors takes skill even in expensive programs with "auto fix" tools. Here Magics detects several errors in the mesh: Use the tool you are most familiar with, and repair any holes, flipped normals, or other defects found in your STL mesh model.
You might have your own favorite program like Meshlab, or Blender. I like to edit STL data in Materialise Magics, or Design X. If your STL mesh is terrible to begin with, the resulting CAD model is also going to have defects. I'm making a new tutorial to give additional information. There are several tutorials which already exists for this topic. Need to convert an STL (or OBJ) file into a "real CAD model"?
