I have imported a 3D-scanned .OBJ file from KScan3D, which is 3D scanning software. I am trying to scan a model car, but would like to remove all the unnecessary points for the purposes of 3D printing. The scan included much of the floor, which I would like to remove.

Below is a picture of the mesh:

What is the fastest way to eliminate the points on the floor? Is there a "drag-and-delete" tool added to recent versions of Blender?

In edit mode, press C, that will enter you into a Circle select. Just hold LMB LMB and drag over what you want deleted. When you have selected all you want to delete, Right click. Then press delete (or x) and chose vertices.

There is also a border selection method, which works in ether edit mode or object mode. Press B, just drag with the LMB LMB held down, when you release it the selection is done. Delete the same way as above. If you selected too much you can unselect it by, dragging with the MMB MMB in either border select or circle select mode.

  • $\begingroup$ By using the mouse wheel you can also increase/decrease the circle size (C select in edit mode). The same tool deselects the vertices/edges/faces, if you press the wheel/third button. $\endgroup$
