Engineering drawings
Tools for people who check drawings: the Dimension Inspector and CN balloons, drawing review, change reports between revisions, first-article reports, parts lists, inspection results and the product map.
See exactly what changed
Overlay lays one revision over the other: the old one in cyan, the new one in magenta. Anything that moved or changed stands out at once.
- Auto-align, adjust colours and contrast
- Mark the differences and save them as a PDF
- Or use the Dual Viewer for side by side
Read a drawing in seconds
The Dimension Inspector reads every dimension, from the text layer or by offline OCR on scans, and numbers them with CN balloons.
- Linear, diameter, radius, angle and GD&T frames
- Edit a value and the drawing updates
- FAI report to Excel, tolerance stack-up from the same list
Number every dimension
The Inspector reads the drawing and places CN balloons in one click.
- Numbered balloons on all dimensions, filling gaps first
A second pair of eyes on every drawing
Drawing review checks the GD&T against ASME Y14.5, then reads the title block, revision table, data tables, parts list and notes and checks them against each other and against the maths behind them.
- Revision, sheet count and sign-off dates
- Gear data (d = m × z), helix lead, keyway depth to DIN 6885
- Notes that contradict the views, wrong material treatments, missing balloons
- Every finding with its rule, a fix and Accept / Ignore
Revision updates in words
The Change report compares two revisions and says what changed: “120 changed to 125”, a hole added, a note rewritten. Then it carries the CN balloons over to the new revision and numbers the new dimensions after the last one.
- Changed, added, removed and moved dimensions
- Note changes, word for word
- Report as PDF or CSV for the ECN
Map the whole product
Build the product tree with assemblies, parts, suppliers and documents. Each block can link to its drawing page and its 3D model, and the map lays itself out.
- Revision and quantity badges on every block
- Shop-floor and flow-chart shapes too
- Export as picture or PDF, or put it in the drawing set
Callouts in plain words
Click a GD&T frame, a fit or a hole note: Explain says what it means.
- GD&T frames, fits, threads, finishes and notes explained in plain words
