Stay on track with Mech-Q Structural

mechq structural menuThe beauty of Mech-Q Structural is that we’ve taken the work out of creating professional looking structural drawings. We have provided you an easy to understand workflow – it’s all laid out, right in front of you, so that you can stay on track with your project.

By choosing Mech-Q you can be sure that you’re on the right path to becoming the most productive you can be at 2D and 3D structural drafting and design.

We keep it simple so you can draw fast

We make it easy, not more complicated … and we want you to get your ducting project done fast and accurate with very little effort. We have designed Mech-Q software to draw the way you do, so you can focus more on the work and not complicated software.

You can fully customize Mech-Q Ducting to conform to your office layer standard – so there’s no need to change the way you already work. Mech-Q creates standard AutoCAD objects – so the drawings can be easily shared with anyone, even if they don’t have Mech-Q.

Mech-Q Structural integrates into your existing CAD menu, ribbon, drop-down or toolbar menu. It also runs in AutoCAD®, BricsCAD and IntelliCAD or as a CAD standalone called AViCAD.
