Recently, an issue was brought to me that seemed a bit odd. I was told that when points are imported through a text file, only a very small portion are being brought in. Strange that AutoCAD Civil 3D would be that fussy about importing points. What is convenient is that we have the ability to control how AutoCAD Civil 3D reacts when importing points.
Let us start in the Toolspace inside the Settings tab. Find the section for CreatePoints under Points > Commands. Right-click on the selection and select Edit Command Settings.
In this dialog box, you will be able to view and change point related default settings. The particular setting I am going to focus on is the one pictured below “Point Identity”…
The Point Identity section defines how to work with points as they are imported into the drawing. Defining these settings prior to brining in points can simplify the process and preserve the integrity of the points in the drawing.
Point Number Offset - Specifies the offset added to imported point numbers when If Point Numbers Are Supplied is selected.
Sequence Point Numbers From - Specifies the starting point number for imported points to be assigned as imported.
If Point Numbers Are Supplied - Specifies how to handle point numbers that are included in the point data being imported:
Use - Uses the point numbers in the point data file.
Ignore - Does not use the point numbers in the point data file, points are numbered according to the If Point Numbers Need Are Supplied setting.
Add an Offset – Applies a fixed additive value to the supplied point number from the source file.
If Point Numbers Already Exist - Specifies how to handle point numbers that already exist.
Renumber - Assigns new point numbers to any imported points whose point numbers already exist.
Merge - Point properties that are specified in the point data file overwrite the point properties existing in the drawing. Point properties not specified in the point data file are not affected.
Overwrite - Overwrites all point properties using the values in the point data file.
Notify - Notifies the user that a point number collision has occurred. The program then opens the Duplicate Point Number dialog box where you can specify how to resolve the collision.
I hope this helps understanding some if the issues that could occur when importing points. Most of the time we just need to adjust some of the settings and things work just fine.
