Point selection
« on: July 26, 2022, 03:43:50 PM »
Does anyone have a solution for the following: select all points that are not connected by an entity (line, polyline, 3d polyline, circle, block...). I searched the forum and didn't find anything similar. Thanks

It depends what you mean by 'connected' - is a point considered 'connected' if it lies on a polyline segment, or must it coincide with a polyline vertex? Is a point 'connected' if it is positioned at the center of a circle, even though it is not touching the circle?

Could it be as simple as do a little (ssget "CP" crossing polygon by making a multi sided very small shape around every point if something is found then ignore. You can use polygon and get vertice points or just make a list of vertice points, I make a minimum of 4 normally a little square.

Thanks for your reply.

Select points that have the same coordinates (2d) such as: the beginning and end of the line, each vertex of the polyline, the base point of the block, the center of the circle... that's what I would get if I exported the coordinates to Excel and looked for duplicates, but it's too much work.

 I posted an example: that would be points 5 and 6

Thanks again
