Drafting techniques and modelling tends to be a highly subjective profession. Many drafters have their own specific tool kits and likes and dislikes when it comes to setting up their work station.
Although layouts and work stations may be widely different, each drafter can provide the same outcome when it comes to providing their client with a specific tailored outcome which meets AS1100 or specific standards.
When it comes to CAD software and desired programs, drafters can get highly supportive and protective about certain programs. I feel this is mainly due to becoming comfortable with quality output under high pressure environments and ever increasing time restraints.
Autodesk still seems to hold the majority of interest and the larger market share when it comes to 3D modelling and 2D drafting. Solidworks seems to have a high volume of users in the south east asian region and with students alike, I am sure many Solidworks users would be highly supportive of their attachment to Solidworks.
