CAD Exchange for Land Surveyors
Land surveyors use CAD Exchange for Civil 3D Survey/Cogo automation, parcel-labelling LISP routines, and field-data import tools that wrangle Trimble/Leica/Topcon raw data into Civil 3D-ready point groups and surfaces. Many listings are built by surveyors solving their own field-to-office workflow pain.
The pain points we hear
Description-key chaos
Field crews don't always follow the description-key dictionary, and the result is half your points landing on the wrong layer. Description-key remap tools fix this without re-shooting the points.
Breakline import drudgery
Connecting field-coded points into breaklines by hand is one of the slowest parts of surface work. LISP and .NET tools that draw breaklines from coded points save hours per project.
Parcel labelling and reporting
Bearing-and-distance labels, area tables, and metes-and-bounds descriptions are repetitive. Survey-specific plugins generate them from parcel objects in seconds.
LandXML round-tripping
Survey data crosses formats constantly — LandXML in, alignment out, LandXML back for machine control. Civil 3D handles the basics; plugins fill the awkward edge cases.

- Description-key remap and field-coding helpers
- Parcel labelling, area tables, legal-description generators
- LandXML round-trip plugins and breakline import tools
- Built by practising surveyors who know the field-to-office workflow
Frequently asked questions
Will these work with my field controller's raw data?
Most accept either Civil 3D's native field-book formats or LandXML/ASCII. For controller-specific formats (Trimble JobXML, Leica DBX, Topcon JOB), look for plugins targeting that vendor.
Do I need Civil 3D or will AutoCAD Map work?
Civil 3D has the Survey/Cogo objects — most surveyor-targeted plugins require it. Some lighter parcel-labelling LISP routines run fine in plain AutoCAD.
Are there tools for metes-and-bounds legal descriptions?
Yes — search 'legal description' on the marketplace. Several plugins generate compliant descriptions from parcel objects.
