Extended Data
MapWorks Label Slopes Video Draw: Draw geometry (hatches, mtext, inserts) based on values in extended data.
Edit: Edits the MapWorks extended entity data on a single object.  Dockable palette automatically shows extended data when one object is selected.
Manager: Allows xdata management operations across a selection set of objects.

Image Process
MapWorks Image Symbols Video Symbols: Go straight from your GPS enabled camera to CAD!  Locates symbols representing GPS Photos (with EXIF data) directly from images.  Creates a hyperlink to the image, projects to drawing system, rotates to view (if bearing data exists), and more.
Web Image TMS Video TMS Images: Builds insertable images from TMS (Tile Map Service) servers.  Produce plan view maps, satellite imagery or terrain images.
Image Inspect Video Link Inspect: Shows linked images in a resizable preview window as you move the crosshair over objects (such as polyline house outlines) containing links.
  GPS Update: Select inserts with hyperlinks and updates the GPS Exif (geotagging information) in source images.  Adds GPS properties to images that never had geotag information.
  World: Inserts multiple TIF/JPG/PNG/SID images based on world files or creates a World TFW/JGW/PGW/SDW file from a selected image (even rotated).

Systems: Includes support for all the systems included in the AutoCAD/Civil3D Projections engine.
  Alt Coords: A system allowing entry and labeling of a second system.  For example if your current drawing is in state plane, you can easily enter values in lat/long or place updatable labels displaying the alternate system.  You can even copy the labels and the alternate coordinates update on demand.

Set the current alternate coordinate system system code.
Enter an alternate coordinate any time CAD is prompting for a point using the transparent 'AC command.
Add an alternative coordinate label at multiple pick points with update options.
Generate a report of selected objects with drawing and alternate coordinates (with or without elevations).
Convert Lat/Long: Reads lat/long text files (DD/DMS), projects to designated coordinate system and writes to point file.
Coord Entry: Enter or pick coordinates which are projected and listed.  Convert between any two systems, even data shifts of NAD27 <> NAD83.
Cursor Tracker: Tracks the coordinates of the CAD cursor in multiple coordinate systems.  Optionally outputs coordinates on ID command ending.
DMS <> DD: Convert numeric values between degrees, minutes and seconds to degree decimal.
Excel Parse: Projects coordinates in an Excel spreadsheet and writes the projected values to adjacent columns.
GNIS Query: Uses the internet to query the Geographic Names Information System with plotting options.
GPS Track: Real time GPS tracking with marker and track data collection, voice guidance, alignment and surface information.
  Open Street Maps:
Import: Imports OpenStreetMap geometry by simply windowing an area inside the drawing.
Set View: Displays OpenStreetMap in your browser with the current drawings viewport..
Set System: Sets and stores the coordinate system for the current drawing.  An intuitive alternative to the confusing AutoCAD set location method.  Optionally zoom to system extents, turn on GEOMARKERVISIBILITY, and set the drawing units (feet/meters) to match the selected system.  Does not require logging into Autodesk 360!
Transform: Projects a selection set of geometry from one coordinate system to another in the current drawing.
MapWorks Web Image (TMS/WMS) Video Web Image: Builds insertable images from web sources such as TMS (Tile Map Service) and WMS (Web Map Service) servers.  In TMS mode you can produce plan view maps, satellite imagery or terrain images.  In WMS mode you can specify any server, get its capabilities and generate an image of a specified pixel size from selected layers.

Columns: This key visualization tool generates geologic columns inside the current drawing.  Simple select the boreholes to process and add them to a sequence list. Control the offset (position from left) by a default offset or by station.  This works by picking two points, the program calculates the stations and populates the grid.

The results (DWF Example) are highly detailed labeled graphics. Each column is bound as a block for easy movement in the drawing.

  Rename: Rename a selection set of parcels by specifying a find/replace string.
  Select: Select parcels by area range, name or site (with wildcards).
Summary: Includes basics such as parcel properties (like area) as reported by Civil3D but also has the ability to collect the parcel bearing/distance and curve labels and do a true map check.  Can even obtain the data from line/curve tables when tags (such as L1, C1) exist.

Instant Results: Immediately upon selecting objects or a defined parcel, the results are shown to the right in our editor.
Real Closure: As each description is being generated, the calls created are collected to calculate closure. These calls are re-traversed, as if the calls were manually entered into a traverse routine to check closure.
Objects Support: For quick legals, you can simply select a closed polyline or a collection of lines and arcs to form the boundary.
Commencement Paths: When you need to describe how to get to the beginning of the description, you can choose a multi-segment polyline or a collection of lines and arcs.
Acquire Descriptions: Collects all the potential descriptions from the drawing, text and mtext objects, along with description attributes from AECC points or point blocks.  When the legal is being created it looks through the potential description collection for the closest description found.  If it's within the designated distance, it is placed in the body of the legal (using the [PntDesc] field).
