I'm been asked to model this pump but not to be totally exact with the features its more to get the main exterior features and dimensions as close as possible so we can fit this into a housing to see how it fits correctly. The thing is this drawing has alot of mission dimensions and not sure how I should go about approaching this design.
Somebody told me to just copy and past the right plane image of how it looks an scale it the thing is the drawing gets so weird because the rear view is a totally different type of feature. I then thought to myself I can extrude certain features separately and then put them together as one piece at the end but the scaling of each image just gets too messy and confusing. Here is an architecture image of the pump. Please let me know how you would approach in modeling this because so many dimensions are missing is the whole issue
