Royal Roos SketchExpress is a user friendly, professional and cost efficient way to transform sketches or draft technical drawings into professional 2D or 3D drawings.


Looking for as-built drawings, reverse engineering drawings or mechanical 3D modelling? Sketch express transforms your sketch to a perfect drawing!


SketchExpress is easy to use, professional. Saving time and money. Read more about SketchExpress below or go directly to the site.

Just a device with an internet connection and go!

The idea for SketchExpress was born working on-site.On-site changes and repairs to existing equipment are often needed, but necessary drawings are either not available, outdated or only accessible as hardcopy or .pdf.While what you need is a good quality technical drawing for repairs and/or fabrication of parts, preferably at once.


With the SketchExpress application it is possible to get CAD drawings - including necessary changes - of good quality in no time. While the draftsman is preparing your drawing you can start up the repair and/or production works for the shipyard/workshop.


Just 4 easy steps from your sketch to drawing:


Step 1

REGISTER: Take a sip of your coffee and wait for the confirmation email.

Step 2

UPLOAD: Specify the drawing/project particulars and upload your sketches to the vault. You will receive an email message when your drawing/project has been accepted.

Step 3

REVISE: Acceptance of the drawing/project links you directly to a draftsman. Communication is easy via notes posted to the application's dashboard. Two revision rounds are included.

Step 4

DOWNLOAD: The draftsman will upload the final version in the requested file format. The drawing is released for download after a final approval quality check by the SketchExpress Administrator.
