Questions

70 Interior

• engine room access - to be considered Wat betreft motorluik kan ik zo niet goed beoordelen. Ben deze week niet op kantoor om tekeningen te beoordelen. Is de ruimte krap of niet toegangkelijk? Kom hier anders volgende week op terug.

To do

Issues

• system assemblies: how to show systems for different lay out versions?
• sound closure engineroom

General

Organise

• 3D model layer control (incl. SC)
• 3D model Xref
• define clearly what is interior / system / outfitting (for example, toilet is interior appliance but solenoid valve is system)
• part catalogue (PDF with supplier info of each part for systems?
• system matrix - create purchase list by means of filtering

30 3D models

11022-30-100 solid model.dwf

• update bow thruster tube

40 Construction

40-100 general construction plan

• done rev E - add angles to thrustersengines
• done rev E - move FW tank 20mm forward (coincides with structure)

• canceled - rudder - hard to watertight weld shaft to top plate because of obstruction by shaft flange - integrate flange into rudder or lower rudder top (remark of Taeke / de Sluis but withdrawn using visit to yard in October)

40-105 shell penetrations

• add additional holes as mentioned for building kit

40-120 bending and forming

• U1-CAB-18P - update template names
• gas locker top is mirrored in nest - swop bending texts
• transom stairs - step ST-01 - change bending into OR mirror plate in nest (first option is preferred)

Building kit

• windlass foundation - cut flange under deck?
