Extract point cloud bounding shape

Post by PablerasBCN »

Hi, I've searched without luck so I guess this functionality is missing.

I would need to extract the bounding yellow spline that is displayed in the 3d view, as shown in top view with ortographic, this is to segment this area from another cloud with less resolution

Hum... not easy currently.

For now you can only read the bounding-box center and dimensions in the cloud properties... and then do the math to deduce were the corners are! (or use the 'Edit > Crop' tool directly, where you can input the center + dimensions).

Hello, thank you, yes looks like a good idea. I can draw the points in CAD and export back as shp. I remember in the past importing shp for triming clouds.

Maybe a small function to convert bounding boxes to a box primitive, it would be easy to implement.

Combined with a modification to the clipping tool to set the dimensions to either a bounding bow or primitive box selected from the DB.

I might be willing to add that if it's essentially what your asking for.

Yep exactly that, the actually visible yellow bounding box converted to Spline , just the square/rectangle seen from above converted to a poliline I could use later on with the segment tool :D
