Pin feedback directly on 3D models

Drop pins directly on 3D geometry to capture comments in context. Each pin saves the exact view state so when you share a markup with someone, they will see the model as you saw it.

Support your feedback with markups or GD&T

CoLab includes all the standard markup tools engineers expect — arrows, shapes, highlights, and text boxes — so you can make your feedback clear. You can even annotate with GD&T symbols and feature control frames.

Assign owners, discuss issues, and track resolution

Every pinned comment becomes a tracked issue. Assign it to the right person, @mention others for input, and use the built-in discussion thread to propose solutions or ask questions. Fields like status and priority help drive issues to resolution.

Markup any PDF, image, or document

Need to review a drawing, spec sheet, or supplier file? CoLab’s markup tools work on PDFs, images, and Microsoft Office files.
