Question 1

What is drawing ballooning?

Accepted Answer

Ballooning is the practice of placing numbered circular callouts next to every dimension, note and GD&T requirement on an engineering drawing. Each balloon number maps to a row in an inspection report, so quality inspectors can verify every characteristic during First Article Inspection (FAI), PPAP or incoming inspection.

Question 2

Which file formats does CADVision AI Pro support?

Accepted Answer

2D analysis and ballooning accept PDF drawings and common image formats (PNG, JPG). The 3D viewer opens STEP (.stp/.step), STL and OBJ models directly in the browser.

Question 3

Is CADVision AI Pro free to use?

Accepted Answer

Yes. You can browse every module freely; signing in with a Google account unlocks running analyses, ballooning and Excel export.

Question 4

How accurate is the AI ballooning?

Accepted Answer

Accuracy depends mainly on drawing resolution: uploading the original vector PDF with Deep Scan enabled gives the best results. Every balloon remains editable — you can drag, renumber, correct or delete callouts before exporting, and the AI output should always be verified by a qualified inspector.

Question 5

What does the exported Excel inspection sheet contain?

Accepted Answer

A four-sheet workbook: Balloon Summary with nominal values and tolerances, Hole Chart, GD&T Summary, and Surface Finish — formatted with pass/fail columns ready for shop-floor use.
