Milestone

For my contribution to the group, I have been in charge of modelling the stud work for the house in 3DS max. In later stages this will also include modelling the gyprock and insulation  Within this task I have also had to research various parts of the BCA to ensure that the structure of the house complies with the required regulations. By contacting a qualified carpenter i was able to get the required information quickly and efficiently to allow for me to sepd less time researching, and more time modelling accurate stud work.

Whilst modeling the house i became aware of a number of complications which i had to resolve along the way. Most of these were related to the structure of the house and to the accuracy of the imported model from Revit. Some of the issues discovered included: beams span exceeding maximum length, glass panelled sections of walls being load bearing, bearers poking through windows, and internal walls exceeding maximum heights.

Model Issues

Issue 1: Roof bearers sticking through windows

As can be seen the roof bearer is actually sticking through the glass window. This obviously cannot be possible and is an error with the Revit model

This problem was corrected be editing the window so that it sits below the ceiling bearer

Issue 2: Roof rafters have too long of a span

The roof rafters in this model span 20m, which is too long to comply with the BCA

This error was corrected by placing a column under a Roof bearer two thirds of the way along the span

Issue 3: The glass window wall was load bearing, but not structurally strong enough

The glass panel wall has a heavy load placed on top of it from the roof and would not be able to withstand the forces placed on it

By placing a steel member along the corner edge of the house, it can take the load from the roof away from the glass windows. This provides a much stronger house.

Export/Import Issues:

After working on exporting the model and importing to SketchUp I noticed that it was specific components that werent being carried over. After examining these components in 3DS Max I saw that the components that weren't exporting properly were instanced components and all I had to do to fix the problem was make them unique.

After making sure all components were 'unique components' they all exported to SketchUp without any issues.
