It seems incumbent upon potential users to find out what else may be available. Many users have developed unique methodologies and workflows to develop SU models, and the software provides users with the ability to work without the need for addons, but allows for content developers to contribute additional ways to use the software. I make use of several extensions which greatly expand my ability to exploit SU’s capabilities, however, the native tools that are included in the program are sufficient to perform all of the tasks indicated in the video that was included in your recent post. I happen to have downloaded 1001bit Tools a few years ago and have used it extensively, but it is not my preferred go to extension. Offset each line representing the interior room surface of the new horizontal rectangles by the appropriate interior wall dimension.Place rectangle objects to conform to the interior dimensions of the rooms in the appropriate relationship to the perimeter.
Offset the perimeter by the exterior wall thickness width dimension.Start by creating the mass structural plan outline.The same configuration can be constructed in less time and requires less cleanup by simply using a defined workflow. Each of the functional activities to produce walls as shown in the 1001bit Tools tutorial are available in the native SketchUp software.
