In mechanical design, we often use a variety of aluminum profiles. In order to facilitate your design work, I have compiled a lot of aluminum profile models. The original modeling software is SolidWorks. In order to be common with various software, I put it Save to various formats, such as sldprt, stp, xt, ig, fbx, etc.
SLDPRT (SolidWorks, filesize: 26.3 MB), OBJ (OBJ, filesize: 9.82 MB), FBX (Autodesk FBX, filesize: 2.55 MB), C4D (Cinema 4D, filesize: 9.52 MB), SAT (3D ACIS, filesize: 33.7 MB), IGE (IGES, filesize: 105 MB), 3DS (3D Studio, filesize: 4.31 MB)
