Where to small is mostly the bigger issue in order to “find” the object within the blender-space. Otherwise it might be to big or to small within blender. forum, then take care that you resize, scale the mesh into dimensions, that blender can refer to. So if you are following the advice within the a.m. Which means there is no scale available anymore. If you import STEP-Files into FreeCad, you are loosing the original information about the size of the object. One thing you should nevertheless keep in mind too: Convert to STL, DWG, DXF, etc., with those same programs or a dedicated converter. The question here was exactly the same as you are asking… An STP file is most likely a STEP 3D CAD file. I would be a bit to much to describe the process within here, but hopefully the following link will show you exactly, what you are “missing”: Here is a list of the most important ones with a short description of the available features: This is the most faithful import/export format available, since it supports solid geometry and NURBS. Within FreeCad (which is, by the way one of the best “not-to-pay-for”-CAD-systems I know by now) you have to do this “work” prior to exporting anything from there to blender. FreeCAD can import and export to many filetypes. (It’s the same, if you want to 3D-Print CAD-objects, by the way - AND! it’s also the reason, why you did not see anything within blender, after export to OBJ - becaause OBJ is a pure mesh-description file-type.) So if you get a CAD-File, you have to take care, that the “parametric-data” are “translated” into mesh-data. In other words: CAD is a description of measurements in conjunction with dependencies. So… there is something, that you obviously missunderstand concerning the “objects” within Blender and those within CAD-Software.ĬAD-Software is working with parametric data.
