I am not entirely convinced of the need for a specific category for Building Design in SU. It seems fairly comprehensive in its ability to provide most (certainly not all) of the industry specific requirements.
Would it not be fair to say that the time required to complete a project will differ depending on the person doing the work? As the experience level increases, the typical expenditure of time consumed in performing specific tasks generally decreases. This is true regardless of the software platform, be it SketchUp, Acad, Vectorworks or anything else.
I understand and agree that little assistance is provided in seeing a video that shows what others may be doing with the software without going into detail to illustrate the process. You may need to search more diligently to find good “how to do such and such” examples for performing real world work, but some examples do exist. Recognize though that each individual approaches tasks somewhat differently so you may be required to modify your standard approach to resolving a particular “real world” issue. A well worded Google search can produce magnificent results.
Some videos developed from the various 3d Basecamps over the years may offer some great technical insight into how to do things. The following list is by no means to be considered exhaustive, but there may be one or two informative items included. Note that each video is about an hour or more in length and there is a considerable amount that is not referenced here:
(Here I think it’s appropriate to request that the SketchUp Team posts all relevant videos from the previous 3D Basecamps in a single easy to reference location!)
Approaching the process with an open mind goes a long way toward achieving the desired result. In this case, it may take more time than a month to become fully conversant with SU to the extent that you can ultimately create a real world project with it. The same applies to using any software. One necessarily must master the tools employed within the software in order to effectively utilize it.
What has worked for me? I immersed myself in the online training videos early on. (I started using SU with version 4.) I found the entire series to be an excellent tutorial resource, especially the Toolbar Series videos. I took the time to download, save and back up all existing SketchUp videos to a hard drive where each resides to this day. I reviewed every one of these videos in manageable bites, only studying a few within a given period until I was comfortable with the concepts discussed. When I felt my reach was not extended beyond my grasp, I moved to different videos and continued this pattern (probably for more than a month) until I became adept at constructing just about any form using the software. Eventually I felt the time had come to learn how to make use of Layout and followed a similar process although there are not as many videos available for that subject, so I resorted to all the printed materials I could find.
Bear in mind that I was a prolific (and expert) AutoCad and Vectorworks user during this period (I actually taught a CADD class among other duties as a professor of architecture), but I later decided to forego using these in favor of SU and LO because the latter software was more user friendly in my view. I like the ability to easily include color and texture in my finished presentations and construction documents. My clients prefer this feature and I actually received praise from contractors! Wow…contractors saying nice things about an architect. Can you believe that? But I digress.
The following playlists and videos were helpful in my learning process and I highly commend them to anyone who wants to improve their SketchUp modeling skills:
Pay particular attention to the playlists that are referenced.
Best of luck in your further learning experiences,
As a somewhat related aside, Trimble may want to consider compiling the many SketchUp Knowledge Base articles into a printed Users Guide. Many learning deficits can be overcome if users have a readily accessible source for referencing issues as they occur. A reference manual will better enable all users to get up to speed in less time.
