As requested by Scott here on LSF, I've made a drawings topic here in the InfiPoints section.
Below are two YouTube videos I made showing a very brief demonstration of some of the features pertaining to drawings that InfiPoints offers. Also attached is the manual for InfiPoints, so anyone interested can do some reading on the features and capabilities that InfiPoints offers.
Drawings can be exported off in DWG/DXF format and edited by a drawing software of your choice before being reimported as a separate drawing, or replacing an existing drawing within InfiPoints.
Also note that drawings and drawing entities are visible within the pointcloud environment.
The first video shows the almost instantaneous creation of drawing entities via the cross sectional lines of the automatically extracted planes. This approach uses a section instead of a clipping box, but the results would be pretty much the same with either approach.
The second video shows the process of automatic segment extraction (similar to the "Mesh-sketch" tool in Design X for those who are familiar with the software), as well as background creation (effectively an orthophoto of the points in the clipping box or section corresponding to the drawing), and some of the export options available.
I plan to make actual drawings available for examination when I have the time to produce a couple very detailed ones.I'm completely new to architectural and building drawings, so it may take me some time to produce them to an acceptable standard. Note that there are no particularly advanced drawing tools like premade door/window/AC unit/etc... symbols and entities within InfiPoints at this time. I would expect this to change if it became a desired feature by the user-base.
