CAD & 3D Models
Download free 3D CAD models of C-BOX CompactPCI chassis and 19″ subrack kits for mechanical design-in. Every model below is the production geometry we cut and assemble in-house, supplied as STEP or Parasolid — ready to drop into SolidWorks, Inventor, Creo, NX or Fusion 360.
Formats & how to use them
Pick the format your CAD system reads most comfortably. Both carry full solid geometry — no meshes, no faceted approximations.
The neutral exchange format. Opens natively in SolidWorks, Inventor, Creo, NX, CATIA, Fusion 360 and FreeCAD. Best choice if you only need to bring one file in and start measuring.
The native kernel behind SolidWorks, Solid Edge and NX. Import is lossless and usually the fastest, with clean faces for mating and interference checks.
Each file is delivered as a .zip (the raw STEP/Parasolid files run 10–45 MB; zipping keeps downloads quick). Open the .zip and import the model into your assembly. Models are supplied for layout, clearance and mounting-hole definition — for manufacturing drawings with tolerances, send us the mating envelope and we return a controlled drawing.
