AutoCAD Civil 3D Tip: Creating User-Defined Point Properties and Import Formats

by Ben Johnson

Point data can come with a large number of unique attribute fields such as multiple elevations on a soil boring. A point can only have one elevation, but the other elevations can be shown using labels once those attribute fields are imported. In order to import these attributes, it is necessary to create User Defined Property Classifications for the points which can then be used to create a new point file import format. The following steps are the workflow for creating User-Defined Property Classifications.

1.  Right-click on the Unclassified dropdown within the User-Defined Property Classifications which is under Points in the Settings tab of Toolspace, and click New.

2.  Give the new field a suitable name, and pick the appropriate field type from the drop down. Do this for every additional field to be added.

3.  After all User-Defined Property Classifications have been added, a new point file format for importing can be created. Open the Import Points dialog box, and click on the Manage Formats button to create the new format.

5.  Name the import file format something appropriate. Pick the default file extension. Delimiters can also be specified. Click on each of the (unused) fields and a dialog box will appear for you to set the field category.

6.  Many of the fields will be standard like northing and easting. Set those as needed, and then add the user-defined fields which you created and named in steps 1 & 2. They will show up in the Column name dropdown. Do this for all of your custom fields.

You can incorporate these User-Defined Property Classifications into your company template file so they will be there anytime you need them.
