AutoCAD Autolisp - Import Export Point Data
AutoCAD Autolisp collection to Export Elevation Data from AutoCAD or to Import Back Elevation Data from Excel. In Land Survey Engineering, Exporting Elevation Data from Excel or CSV files is a regular requirement and ESurvey Lisp - Addresses this Problem nicely. Point Data representing Easting, Northing, and Elevation along with Remarks can be imported or Text from AutoCAD Can be Exported back to CSV File.

Importing and Exporting Point data in CAD using Lisp routines. When Survey Data has to be imported with the line joining, block insertion Etc. there is a full-featured software for the Same, ESurvey Topo map. If you have to import simple point data it can be done with Lisp routines provided with ESurvey lisp itself. Point data come in different combinations and point data in the drawing is also exported with different options. You may want to create points in 2D sometimes and 3D for different requirements. Considering all these requirements, 3 import and 3 Export options are provided.
EXP1: Export Selected Objects to CSV File X, Y, Code
While working with drawings it is a common requirement to export the elevation texts or codes along with respective Eastings and Northings to a CSV file. Using ‘EXP1’ when you select multiple texts, a CSV file named ‘ImpExp1’ will be created in the Temporary Directory.
EXP2: Export Selected Objects to CSV File X, Y, Z, Code
To export codes of a drawing along with its Eastings, Northings and the Z value use the EXP2 command. However, make sure that the texts representing the codes have a Z Value and are present in the code layer. A CSV file named ‘ImpExp2’ will be created in the Temporary Directory.
Exp3: Export Selected Objects to CSV File
To export codes and elevations of a drawing along with its Eastings and Northings to a CSV file, use the EXP3 command. Note that the insertion point of the elevation and the Code should be matched to get the proper results all the codes have to be present in the ‘Code’ layer and elevation to be present in the ‘ELev’ Layer. A CSV file named ‘ImpExp2’ will be created in the Temporary Directory.
IMP1: Import Point Data in CSV File as CAD Text - X Y and Code
To work with this command first a file with the name ‘ImpExp1’ is to be created in a temporary directory. The Eastings, Northings, and codes should be present in the 1st, 2nd and 3rd columns. Using ‘IMP1’ texts representing Code will be created in CAD with respective Eastings and Northings.
IMP2: Import Point Data in CSV File as CAD Text - X Y Z and Code
To import codes along with their Z value into AutoCAD from a CSV file, use the ‘IMP2’ command. Create a CSV file with the name ‘ImpExp2’. The Eastings, Northings, Z values of the code and code should be in 1st, 2nd, 3rd, and 4th respectively. Using ‘IMP2’ texts representing Code will be created with elevation in CAD with respective Eastings and Northings.
IMP3: Import Point Data in CSV File as CAD Text - X Y Elevation and Code
To import codes along with elevation into AutoCAD from a CSV file, use the ‘IMP3’ command. Create a CSV file with the name ‘ImpExp3’ in Temporary Directory. The Eastings, Northings, elevation, and code should be in the 1st, 2nd, 3rd, and 4th column respectively. Using ‘IMP3’ texts representing Code, Elevation will be created with respective Eastings and Northings.
SUY: Extract the Text within a Polygon Boundary
While working on land acquisition projects, it is always required to make the list of survey numbers falling within a selected boundary. Using the ‘SUY’ command you can select and sort all the text values representing the survey number within the selected boundary and place these selected numbers anywhere in the drawing. Also, a CSV file is created with these selected survey numbers in a temporary directory.
