ISO 2768 mK Table: General Tolerances Explained
What ISO 2768-mK allows: the f/m/c/v linear table, radii, angles, H/K/L geometric classes, a worked bracket, and why ISO 2768-2 was replaced.

ISO 286 Fit Selection: H7/g6 vs H7/h6 and Friends
Choosing an ISO 286 fit by function: preferred hole-basis pairs loosest to tightest, what each is for, bearing-seat rules, and what changes the pick.

Does Position Tolerance Belong in a 1D Stack-Up?
When a Ø position zone contributes to a linear stack-up and when it cannot — halving the zone, MMC bonus and datum shift, and where 1D must stop.

Can You Do Tolerance Analysis in NX? 3 Options
NX authors world-class GD&T but ships no stack-up solver. The three real paths — enterprise plugins, the spreadsheet, file-based tools — and who fits each.

3DCS Alternatives: Enterprise to Self-Serve Tools
Real options for tolerance and variation analysis — 3DCS, CETOL, Enventive, Siemens VSA, the spreadsheet, and SuperNX — who uses each and how to choose.
