Turn technical ideas into clear, scaled visuals.
Create professional conceptual sketches without the complexity of CAD software. Draw existing conditions, proposed layouts, equipment arrangements, and project options, then annotate, review, and share them with clients.

More precise than a whiteboard. Faster than CAD.
Hand sketches are fast but unclear
Quick sketches on paper or a napkin are rarely to scale and often look unprofessional in front of a client.
Whiteboard tools lack real scale
Miro-style boards are easy to use but do not provide reliable dimensions or units for technical communication.
CAD is precise but overly complex
AutoCAD and Revit are powerful but slow and intimidating for early-stage conceptual discussions.
Sketch Engine fills the gap
The simplicity of a modern whiteboard, with just enough technical precision to communicate clearly and professionally.
Communicate technical ideas with confidence
The right balance of simplicity and precision for conceptual technical communication.
Draw to Scale
Use metric or imperial units, define a scale, enter exact dimensions, and align objects to a configurable grid.
Communicate Clearly
Combine geometry, dimensions, labels, arrows, notes, and colour-coded layers in one professional visual.
Compare Project Options
Represent existing, proposed, and removed elements so clients can immediately understand the intended change.
Share Professionally
Export a clean conceptual-sketch PDF or PNG that can be reviewed by clients and project stakeholders.
