ddbexpress Engineering & Software


Multiple clipping planes and Manual and Automatic dimensioning of features on clipped sections.


Writing modular code so it can be integrated quickly into existing software’s large code base.

Technical challenges:

  1. Adding 3D dimensions in the Eyeshot viewport.
  2. Decide direction and distance from selected end points and orientation of the dimensions considering viewing direction of camera.
  3. Determine capping edges generated by clipping plane and implement intelligent algorithms to add dimensions automatically and these are placed elegantly.


ProtoTech’s expertise in the Eyeshot APIs and 3D rendering helped ‘ddbexpress Engineering & Software’ to implement the feature for end users within the scheduled time.
