Linking points with a 3dpoly line automatically


Recommended Posts

I’d like to know if you have one LSP that links points with some 3D POLY LINE between then.

Something like an outline, just like this:




It is link points given by coordinates. I upload from a device the coordinates and import points to AutoCAD, but I have to link them like the picture. It doesn't have an order, but the 3d lines are only the outside. It will be good if I can select them to link or even link by layer, because I work with tunnels and each point represents the edge of it.

From a surveying sense and it will work in 3d you need to think of it as strings lets take a sq repeated horizontally the survey pts would look like this as descriptions








so 1-5-9 join 2-6-10 join its in the point descriptors "String description" all 1F join in sequence


String example.jpg See lines joined based on their code description a string numberis not displayed 01403 & 02403 to distinguish between kerb 1 and 2.



If you did all you points this way and brought it into CIV3d you would get a 3d tunnel. The way to go here to do some form of crossection linking back to the previous one using a pt&desc match as you go a new string would stop or start the joins.

finding the outline is the most complicated part, but I found it.


Try the attached PtOutline utility with the 3D option.

In the Attachments I zipped two LSP VLX that does it very well.

I hope it will help you as it helped me.
