Free 3d Cad Mac
SolveSpace is a parametric 3D modeler is developed by Johnathan Westhues. It is a 2D and 3D CAD program, perfect to do some 2D models thanks to great drafting tools, or to elaborate good mechanism designs. Its CAD tools include Bezier curves and NURBS surfaces. SolveSpace is available with Windows Mac OS and Linux. Here is a list of the best deals in free or inexpensive CAD programs. One quick note, if you’re a Mac user then check out our list of 3D CAD programs for the Mac / OSX. Free Form 3D Modeling Programs. 3D modeling programs are used to make models for animations or video games and those models are never meant to leave the computer. OpenSCAD IRC channel moved to libera.chat.Chat with us in channel #openscad. Open SCAD is software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and Mac.
Most programs on Windows have an alternative available on the Mac with the notable exception of CAD/CAM programs; there are relatively few popular CAD/CAM programs that run on OSX.
The list below is a good starting point for Mac-friendly 3D CAD programs:
OnShape
OnShape (Free - $80/Month)- OnShape is a new cloud-based CAD program from the same team that created Solidworks. It runs completely in the browser so it runs on PC, OS/X or even an iPad. There’s a range of pricing options and for many users, it’s totally free.
solidThinking
http://www.solidthinking.com/(Call them for pricing) solidThinking offers a number of CAD programs that seem to be very powerful. They seem to have a business model where you contact them for demos and pricing so they may only be an option if you’re really comitted to learning more about their products.
Via Cad
http://www.punchcad.com/($99) Via CAD is a very capable 2D/3D CAD program that uses a “real” CAD kernel and it capable of creating good parts for relatively little money.
Sketchup
http://sketchup.com/($500 for Pro or Free for Standard) Sketchup is a very easy-to-use CAD program that scales well from tiny parts up to complete buildings. If you don’t have a lot of CAD experience, then you may find this to be a gentle introduction to the whole process.
One thing to note- only the Pro version is able to export an STL file for use in CNC applications. There are plugins available for free that add this function to the free version. Googling “Sketchup STL Plugin” should give you a list of the options that are currently available.
3d Cad Programs For Mac
FreeCAD
https://www.freecadweb.org/(Free) FreeCAD is a totally free and open-source parametric CAD package. Many of the open-source CAD/CAM options are a little rough because they are not incredibly popular so they don’t get as much development attention as more popular open-source programs.
That being said, FreeCAD is worth a look if you want a parametric CAD program that doesn’t have huge maintenence fees (like many do) or risk having the price terms changed in the future (like Inventor Fusion).
A common question from new CNC software users is, “What CAD program do you recommend?” As you might guess, the answer is, “It depends”. Here is a list of the best deals in free or inexpensive CAD programs.
One quick note, if you’re a Mac user then check out our list of 3D CAD programs for the Mac / OSX.
Free Form 3D Modeling Programs
3D modeling programs are used to make models for animations or video games and those models are never meant to leave the computer. These programs will let you design complicated shapes easily but they can make it more difficult to design mechanical shapes to exact dimensions.
Blender (Free) - Blender is a free, open source 3D modeling program. The interface is very non-traditional and will require some adjustment if you’ve got experience in a more traditional 3D design program. Amazon stocks a ton of books about Blender so it should be easy to find some material to help you out.
Silo3D ($99-$159) - Silo3D is a subdivision modeling program that, like Blender, is not primarily targeted at users trying to design models to be machined. It is incredibly powerful and the interface is easier to learn than Blender. This is a great value if you’re looking to model organic shapes.
Free Form CAD
Free form CAD programs let you design dimensionally accurate models but don’t impose any structure or workflow on your methods.
Sketchup (Free or $500)- Sketchup is a CAD program that was originally targeted to the architectural market. It is a very simple program to use but it isn’t well-suited for organic shapes. In 2006 is was acquired by Google and a free version was released. The free version will not export an STL file but several people have written plug-ins that allow Sketchup to export an STL without paying for the full version. The various approaches are discussed on their halp page
Viacad 3D ($199)- Viacad is a simple , powerful 3D CAD program. It isn’t as popular as some of the others here but it’s inexpensive and you can get up and running quickly. It is available for Mac and PC, making it unique in this list.
MoI ($295)- MoI (Moment of Inspiration) is a 3D CAD program that was designed to be usable on tablet or pen computers. Because of this, the user interface is simple and doesn’t require a lot of typing. It was written by a single guy, who was one of the original developers of Rhino, so it’s powerful without being bloated. It is equally well-suited to organic or mechanical shapes. Without a doubt, this is one to try.
Rhino ($995)- Rhino is one of the most powerful and flexible CAD programs anywhere. It has every kind of tool you could need and , like MoI, is equally well-suited to organic or mechanical shapes. It isn’t inexpensive but it does almost anything you could need. If you happen to be a student then you can get a significant discount. Version 5 will also be avialable on Mac OS X when it is released.
Parametric CAD
Parametric CAD programs keep the entire history of the model as it is being built. If you find the need to change a shape or dimension then you just go back in the history, make the change, and the model will be rebuilt automatically. If you make a big change then you may have to do a little work to get the model rebuilt properly but it’s still going to be faster than a program like Rhino. Parametric CAD programs are incredibly powerful if you are willing to spend the time to get your head around the workflow.

Free 3d Cad For Mac

Alibre ($199- $1400)- Alibre is a very powerful parametric CAD program that is available for very little money if you only need to export to STL. They take a lot of pride in the fact that you can do 99% of what the very expensive programs can do at a fraction of the cost. As a comparison, Solidworks, one of the most popular programs in this category, will cost you a minimum of $3500 to buy it and $1200 a year for updates. The $199 version of Alibre is the most amazing deal on this page.
Although it’s in no way a low-cost program, Solidworks works very well with MeshCAM and it’s very popular with MeshCAM users. Just in case you’re one of them, we’ve got a Solidworks CAM page with some instructions to help get you started.
