Transformation of drawing elements by coordinate transformation according to Helmert.

Zero Level Pro plugin for Autodesk® AutoCAD® is designed to benefit users for calculating the vertical section levels in all engineering fields to save time and effort and give more accuracy.

This plug-in can be used with Autodesk® AutoCAD® to quickly collect the area and length of a group of selected polylines grouped by layers.

Program to easily change the layer name or name of the selected block.

Extracting Coordinates for elements (Polylines- Points - Blocks-3Dpolylins) in (X, Y, Z) and export it in 4 formats (txt-csv-sdr-gsi)

Easily convert those old leaders and text to Mleaders!

Pick on a drawing entity and place text in the drawing listing the entity's area.

ID a point on the screen and label it with a Mleader.

Identify Northing and Easting of a point on the screen

Moves entities to the closest intersection of a user defined grid.

Import & export objects, images, terrain meshes, and 3D models between Google Earth™ and Autodesk® AutoCAD®.

This tool is for surveying. From a selected polyline, the app will create a Pline Closure text report, shown in Autodesk® AutoCAD® Text Window, and/or saved to a text file.

Generates successive polyline approximations of lwpolyline/polyline3d objects to smooth out the original shape but keep the overall polyline trend.

Morphs one polyline into another by generating intermediate polylines at arbitrary stages of the process.

Attempts to improve a field survey in certain cases by creating a smoothed out version of an original 3d polyline
