    STEP file format for CAD 3D models is the most used one and most stable.
    IGES works, but has many sub-formats or dialects, so some translations get screwed up.
    STL is only for 3D printers and similar to LW polygon obj.

    Designsparks is free, but a paid module is needed to export to STEP, so freemium I would say.

    Onshape is a free cloud CAD package, but the free tier means that your data is public, no-go for most people.

    Alibre Design Professional for around 1000$ and 300$ annual support is the second cheapest CAD package. Though you may need the Expert version at higher cost. Free 30 day trial to check what you need.

    An example from the vehicle industry.
    Step 1. Sketch on paper by Designer
    Step 2. 3D surface model in Autodesk Alias by Styling Engineer
    Step 3. 3D Solid model (surface with thickness, drafts and other manufacturing limitations added) generated by Mechanical Engineer in CAD software like CATIA.
    Step 4. 2D drawing on paper or digital for GD&T (tolerances) generated by Mechanical Engineer.
    Step 5. Tool maker checks the 3D solid model and drawing and start to design the tool.
    Step 6. First shot parts are out and look boring compared to the original cool design sketch.

    ViaCAD Pro is a tad cheaper if you buy an old version like 7 Pro and upgrade straight to 11 Pro.
    Lightwave can also be used for product illustration and animation, missing in ViaCAD but included in the pricier SharkCAD.

    i see it is $500 these days, still alright.
    i was lucky to get it at $250 back in 2011. an upgrade from any "Pro" version is $150.

    ViaCAD 11 may have lost the SubD to NURBS function in 10. From a forum thread, check with their support if the function is critical for you.

    Update with PowerPack is 250, may be worth the extra 100 for PowerPack.

    Thanks, found it,

    i might be moving away from anything CNC related / injection molding related though,
    takes too much time, and is too expensive. (for a 1man company)

    would be nice to see the injection molding technology move forward.
