Powerful CAD software for the Mac.
HighDesign LT is the light-weight, precise, affordable CAD software for your personal drafting needs. Easily create, edit and document drawings with the full set of drafting tools and editing functions, all with a modern, effective user interface.

Use the professional-grade drafting tools, save time and clicks with the handy editing functions and apply color gradients, hatches and textures for compelling presentations.

Optimized for 64-bit processors and designed to take advantage of core macOS technologies, HighDesign LT is fast, accurate and intuitive at the same time, so you can become productive right away.

HighDesign supports both US and metric unit systems, as well as angular and area units, and provides architectural and engineering drawing scales.

The User Interface is designed to be responsive and fit different screen sizes and configurations, maximising the use of space and focusing on the project. Support for retina displays, the sidebar and input bar, the properties Inspector, light and dark themes, and many customization options allow the software to adjust to the user's context and preferences.

The Radial Menu brings together all the relevant tools and functions in one, convenient visual menu. The tools are presented where they are needed according to the current context, allowing the user to stay focused on the drawing.
