Select structure by coordinate

luiz.silvaNDFA2 — Fri, 30 Apr 2021 09:24:00 GMT

Good Morning, first I'm sorry for English because I don't know how to speak. I am developing a routine in C # to build a network from data that is in .txt. The big problem is that I need to check if there is a structure before inserting a new one, if I have to pick it up. I've tried to use all forms of selection such as: SelectFence, electCrossingWindow ... and I can't get the structure that has already been launched. Does anybody know how to solve this?

Is this possible highlighting Each network operates in a loop

Then confirm the names of the manholes

Good morning hosneyalaa, I didn’t understand how to explain how to do it?

I tried to make a lisp function with 4 arguments that would be to set up a start and end point and use (ssget "_F" '(ptstart ptend)) to get the entity, but when I call it with .NET I get the message "; error: bad point argument".

In fact the lisp function would be to check if you have a structure at the point and if you have to return that entity.

How would you send a snippet of code showing how to use this function that you informed?

I already tried the solution "https://spiderinnet1.typepad.com/blog/2012/09/autocad-net-editorselectfence-pointcollector.html" but for some reason I don't know he doesn't select the element of Civil only cad entity , for me it would be the best solution since I don't need a lot of interaction and the intention is to create 150km of network. I will try the solution "https://forums.autodesk.com/t5/civil-3d-customization/select-multiple-structures-by-name/td-p/7987765" and give feedback if it worked.

@luiz.silvaNDFA2 as @hosneyalaa has been describing, do not try to use a selection (I'm not sure why it's not working, but it is inefficient anyway). Instead, get all of the existing structures and check against those. I suggest not mixing lisp and c# code, do everything in c#.

I would create a list of Point2d, loop through the existing structures and add the 2d location to that list. Then when creating structures from the Excel file, see if the list contains the location of the structure to insert, if so, skip that point. I would actually have a small function that checks if the 2 points are the same within a specified tolerance, say 0.5 feet. When you add a structure, be sure to add it's location to the Point2d list.

hosneyalaa and Jeff thanks for the help, the function worked perfectly. Thank you very much.
