FROM A FILE TO A CLEARER CONVERSATION
A model is only the beginning. Keep the measurements, assumptions, and questions that make a useful review.
Orbit, clip, and measure your STL. Save distances, angles, labels, and colours. Use two views to keep different perspectives in the same discussion.
Review orientation, machine dimensions, and quantities. Estimate weight from accepted geometry and selected density, with part, support, and waste inputs kept distinct.
Record process questions, build a quotation from your own rates, and share a selected summary image. Save an editable project to continue the conversation later.


A PRACTICAL SECOND LOOK
Choose a process, inspect the model, and make the next step clear. PocketAdditive keeps calculated results and your own inputs visible together.
