Thanks - that's Interesting... My 3D modelling in another system is strong for fast concepting but the drafting tools, whilst fairly good aren't up to date and are limited in functionality. From what you demonstrate, your 2D annotation tools and 3D inspect for clearance or assembly / dis assembly with the 2D section analysis is what i'm currently missing. Could I import a step file of a design and use BricsCAD Mechanical going forwards from there?
