Cadastral Tools is a set of tools/commands for cadastral drafting in Autodesk AutoCAD. This plugin contains commands to help with point creation and common measurement practices with cadastral surveying.

The commands make use of transient graphics to help displying information to the user.

The library was originally developed for AutoCAD R21.0 (2017) and .NET Framework 4.6.1. I have included project files for later releases of Autodesk AutoCAD.

• InverseCL to display inverse information between two points in the command window.
• InverseOS to display similar information as the InverseCL command but displays on the screen using transient graphics.
• InverseCHOS to display inverse information along a baseline specified by two points at perpendicular offsets.
• PtDistanceOnLine to create points on a baseline between two specified points.
• PtIntFourPts to create a point at the intersection of four points.
• PtBetweenPts to create a point between two specified points.
• PtOffsetBetweenPts to create a point between two specified points at an offset from the baseline.
• PtIntAngleDistance to create a point at the intersection of a bearing and a distance.
• PtIntDistances to create a point at the intersection of two distances.
• PtIntAngles to create a point at the intersection of two bearings.
• PtAngleDistance to create a point at a bearing and distance.
• PtOffsetLine to create a point at an offset from a found intersection.
• PtProdOfLineDist to create a point on the production of a line at a specified distance.

• Visual Studio 2022
• .NET Framework 4.6.1 to 4.8.1
• Git for Windows

git clone https://github.com/puppetsw/AUS-Cadastral-Tools

To build Cadastral Tools open the AUS-Cadastral-Tools.sln file in Visual Studio.

If you need to build for a different release of AutoCAD, you can use one of the exisitng release projects by removing the AUS-Cadastral-Tools.R21 project and adding the relevant existing project from the source directory.

Right click on AUS-Cadastral-Tools.R21 project in the solution explorer and select Properties.

Click the Debug tab and modify the Start external program path to match your version of AutoCAD. See below image.

Feel free to contribute in anyway you see fit.
