From point cloud (3D) to dimensioned plane (2D)

About :
In this video I show you the process I follow to go from a dense point cloud to a two-dimensional representation. Although the point cloud has a lot of useful information, we are still a bit tied to the 2D of plans, elevations and sections. But precisely because the point cloud has a lot of information it is possible to exploit it to bring out what is needed in this sense. Here I work on a portion of an aerial photogrammetry cloud relating to a soccer field. In Cloud Compare I create relevant points, a mesh of regular points and a polyline delimiting the area. In Thopos I import the points found in Cloud Compare and transform them into topographic points. These are drawing entities that have associated: ID, Elevation and X,Y Coordinates. They resemble topographic points detected in the field. Even if they have not been detected by any tool. In CAD I import everything and arrange the rest of the drawing. There are many ways and many tools to achieve the same result. I will show you the one I use and that works for me. If you want to share your way and open your toolbox it would be very useful for everyone! You can find a lot of information and videos about Thopos on the You Tube channel Thopos TV - / thopostv Subscribe to the 3DMetrica Telegram Channel: https://telegram.me/tredimetrica Find out more and subscribe to the newsletter here: https://3dmetrica.it/ And, if you want, you can choose to become a 3DMetrica funder and producer with a support that you can give on Patreon to the page / 3dmetrica
