Downloading DesignFreeQ 2.18 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Shark Designer. We recommend checking the downloaded files with any free antivirus. DesignFreeQ for Mac lies within Design & Photo Tools, more precisely 3D Modeling.
From the developer:
DesignFreeQ drafting program is used in CAD/CAM to produce high precision drawings, but also in areas like technical illustration, documentation and education. Due to DesignFreeQ’s unique Inference Engine, drafting is made as easy as sketching on a piece of paper. The user interface is minimalistic but incredibly powerful and intuitive. Even novice users can quickly create precise drawings in both 2D and 3D.
You may want to check out more software for Mac, such as TkMatMan, 3D Invigorator PS or Microspot Interiors Pro, which might be similar to DesignFreeQ.
