Canterbury Solid. Works User Group CANSWUG About Me – Karl Celeste • Design Engineer for Motovated 1. 5 years • Worked on Designline projects both offsite and in-house • Solid. Works advocate

Canterbury Solid. Works User Group CANSWUG Designline • Rolleston Company • International Office in Charlotte NC • Moved to 3 D CAD ~2006 • Sell their buses worldwide

Canterbury Solid. Works User Group CANSWUG Motovated Design & Analysis • Christchurch based • Advanced Mechanical Engineering and Analysis via CAD • Helped Designline in transition to 3 D CAD • Continued on to US Hybrid Design/Modeling

Canterbury Solid. Works User Group CANSWUG Challenges with Large Assemblies • Load time • File size • Even larger drw (x 10 not uncommon) • Write Access • Position Accuracy • Safeguarding modification • Robust mates, stability etc. over time

Canterbury Solid. Works User Group CANSWUG Client Needs • • • Flexibility Common & differential parts SW 2007 Multi-user environment without PDM Clear & easy to understand model structure Drawings mainly for BOM & general location

Canterbury Solid. Works User Group CANSWUG Large Assembly Management Base Part (skeleton) • Contains base level geometry – Good control & access – Quick visual check – Reference the same critical geometry • Mate planes e. g. axle CL, step heights – Driven by base sketches – Snap into place – Mates independent of model geometry – Simplifies mates – Easier to find if it does fall over

Canterbury Solid. Works User Group CANSWUG Large Assembly Management Folder Structure • Flat as possible – Reduce mates – Reduce depth • Model naming convention – Assembly or part – What area of the bus – Only an indication of which assemblies its used in – Common or differential part – E. g. 129004 rear chassis assembly, 128042 seat riser assembly, 129488 part

Canterbury Solid. Works User Group CANSWUG Large Assembly Management • CAD Model Full Bus Chassis Side Frames Roof Interior Floor

Canterbury Solid. Works User Group CANSWUG Large Assembly Management General • • Don’t model in context! Fully constrain sketches 1 drawing per model Display ‘shaded’ not ‘shaded with edges’ • Use supplier models or model over them

Canterbury Solid. Works User Group CANSWUG Large Assembly Management General • Remove all unnecessary info • Macros to speed up tedious processes e. g. re-use drawing, custom properties, pdf/dxf • Could use Speed Pak if using SW 2009+ • Avoid complexity
