Where have all the profits gone?
Some CAD drafters love 3D work. I love 3D modeling. The problem I find is most people want this service for free. Unless you are working for a large firm with the resources to buy you the software to do 3D modeling and you are fast enough to be able to learn the program well enough to be able to charge your time to the project, you are wasting the clients and your employer. Why you may ask? The reason is that most small shops want to get out a set of plans that will suit the building and planning departments in their area, and not break or whittle down the projected profits.
Think about the initial cost of the software that has 2D/3D capabilities. They are all expensive and the learning curve will "knock the socks" off of any junior staff who will have to go through all of the downtime associated with the huge learning curve that is a product of so much built in utility. Even the seasoned veteran who knows everything there is to know about CAD will find learning these programs daunting. They aren't tossing drawings out the door for reproduction until they also deal with the downtime learning the program. Most even have to go to costly training sessions to learn how to use them. And, we are not speaking of the new guys or gals here who. These seasoned vets's get paid quite well to go through the training and then become proficient with the new "magic drafting and 3D modeling" software.
There are good things about the 2D/3D paradigm in design software. Expect a lot of expense to get good quality work out the door to the client. Expect to pay for traveling for training. Especially, expect to do this on a constant basis. Software companies are publicly traded and their investors expect to see a good return on their investment. This means you will deal with upgrading your CAD software every year. That can only mean one thing, $$$$$!
