InnerSoft CAD is an AutoCAD plug-in that provides Civil and Survey tools, Estimating, Counting and budget measurement features. It facilitates the export and import of MS Excel files.

Additionally, InnerSoft CAD allows you to import vertex coordinates for a set of 2D or 3D polylines using three different methods. You can also import points from Excel or Texts with an insertion point, making it easy to integrate data into your project.
One of the most useful features of InnerSoft CAD is the ability to extract all block definitions of a drawing in individual AutoCAD files. This makes it easy to organize and manage large projects with multiple block definitions.
Other features of this plug-in include the ability to sum the area or length property of a set of objects, sum the accumulated distance of a user-defined walk in the drawing, draw the longitudinal profile of a terrain or set of surfaces, triangulate a set of points, and mesh a model surface.
You can also take measurements on AutoCAD for construction project budgets and create, open, or save different libraries containing a series of AutoCAD drawings organized by books.
In addition, InnerSoft CAD comes equipped with a set of powerful drawing tools that allow you to draw a polyline graph, a 2D & 3D convex hull, lines, planes, circles, and spheres by regression from a selection of points. You can also draw clothoids, parabolas, circular transition curves, Wholly Transitional Curves, clothoid transition curves, and parabolic vertical transitions, giving you the freedom to create complex designs with ease.
Overall, InnerSoft CAD is an essential tool for anyone working with AutoCAD in the construction industry. With its wide range of productivity tools and drawing features, this plug-in makes it easy to manage projects, analyze data, and visualize designs in a streamlined and efficient manner.
