CaRMetal

Advancement in technology has made it possible to create virtual designs of every project before actually building it. This allows more precision to be added, with specialized applications such as CaRMetal putting a friendly environment at your disposal to create various 2D and 3D structures, get them analyzed and export results.

Running the application brings up a pretty visually appealing and intuitive interface, with side panels you can toggle for quick access to project objects, as well as the rich library of content. The rest of the space represents your interactive workspace.

You'll be able to create a large variety of objects, mostly based on points. Construction tools let you carefully place points, lines, vectors and a lot more geometrical functions and figures. Moreover, there are controls for a 3D environment, with the possibility to add edges, cubes, tetrahedrons and coordinates.

Customization plays a small role in this type of design, with options only to adjust the thickness of lines, set colors, and type of line. Since you can also add text, fonts can be enhanced a little as well.

On the other hand, precision is an area better covered, with a decent amount of tools to work with. You can enable a grid to better snap objects, and even use an abundance of functions and mathematical expression to obtain calculus.

Programming enthusiasts also have a shot at expressing skills, with a built-in script editor. With it, you'll be able to issue sets of commands to obtain different values or simulate multiple situations. A few options are available to add controls, such as custom sliders, buttons, drop down menus and a few more, which you can link to scripts.

CaRMetal is a decent objects design tool, with an intuitive interface that quickly gets you up and running, a large variety of creation and editing tools at your fingertips, as well as support for multiple projects. It's only disappointing to see the lack of exporting options other than a few image file formats.
