MicroSurvey CAD 2010 is now built on the latest IntelliCAD engine, IntelliCAD 6.6. For a list of IntelliCAD fixes, see below.

Easily offset Lines in your drawing by varying offset distances. This is similar to the existing _PARALLEL or _OFFSET command but is easier to use.
New command: _MS_OFFSET (MsTools | Offset Grid Lines)

Calculates a 3-point inverse to determine the interior or exterior angle between two lines, and displayes the angle to you in both decimal degrees and degrees-minutes-seconds.
New command: _MS_SHOW_ANGLE (MsCogo | 3-Point Inverse)

MicroSurvey CAD now includes a "Check for Updates" feature. This new command is available in the Help Menu.
MicroSurvey CAD is now configured to silently look for updates according to the preferences setup by the user. When an update is available the user will be notified. Updates are automatically downloaded and installed.
New command: _UPDATECHECK (Help | Check For Updates)
New command: _UPDATECHECK_CFG (Help | Auto Update Preferences)

A new command is now available in the Active Traverse Editor, which will normalize Face 2 total station measurements to Face 1. This is necessary for users who want to perform a 3D Least Squares Adjustment.
Improved command: _MS_EDIT_RAW_DATA (MsTraverse | Active Traverse Editor)

Now works with Polylines, LWPolylines, and 3DPolylines.
Improved command: _AUTOP (MsPoints | Auto-Add Points to Objects)

We have made several improvements to the star*net exporter, which allows traverses from MicroSurvey CAD to be adjusted in star*net more easily, including the following:
Units and Order records are now added to header section.
Date Processed note recorded in the header section.
Directory and traverse file that the export is based on is recorded as a note in the header section.
We do not record a C record for every setup anymore, only for the inital setup points.
FieldGenius Multiset backsight measurements are now exported as DV records.
FieldGenius Multiset foresight measurements are now exported as M records.
Angle format in the DAT file now uses the Starnet notation of degress-minutes-seconds. For example angles will look like: 90-00-34.55 instead of 90.003455
Distances are now displayed in the DAT file to four decimal places.
Undefined distances in DV and M records are now exported as ? instead of 0.0000.
Fixed odd behaviour when selecting the DAT file export directory. It would always default to C:\Star
Exported DAT file is automatically opened in Notepad after export for review.
Now available in MicroSurvey CAD Basic, Standard, and Premium versions. (Previously Standard and Premium only)
Improved command: _STAR_NET_EXPORT (MsTraverse | Star Net Interface)

IntelliCAD 6.5 Engine
MicroSurvey CAD 2009 is now built on the latest IntelliCAD engine, IntelliCAD 6.5.
Performance enhancements
Performance has been enhanced considerably when using real-time zoom, real-time pan, and saving drawings.
Toolbar and menu icons
The IntelliCAD user interface has been enhanced with new 24-bit icons for all color toolbar icons and menus.
Use polar tracking
Polar tracking is a new tool used to help you draw with precision. When polar tracking is turned on, guides display on the screen automatically at specified polar angle increments.
Check the spelling of text
You can check the spelling of single-line text, multiline text, paragraph text, attributes, attribute definitions, and dimension text. Additional features include loading dictionaries from different sources, including various languages, and adding your own words to a custom dictionary.
Copy multiple entities
Now it’s easier to copy multiple entities. IntelliCAD defaults to prompting for additional copies of selected entities during the Copy command.
Work with additional image formats
The number of image formats available for drawings has been expanded. You can include images in the following formats: ECW, JPG 2000, ERS, ALG, HDR, DAT, DOQ, FST, NTF, ASC, IMG, DEM, DDF, DT0 and DT1, and HDF (including MET, L1R, and L1G).
Layer toolbar
You can now use the Layer toolbar to specify layout-specific layer settings. The Layer toolbar dynamically sizes, making it easier to manage large layer lists or drawings with long layer names.
Customize the status bar and menus using DIESEL
You can use DIESEL from the command line, in MNU menu files, and in LISP to customize the status bar and menus.
Use new and enhanced system variables
New or enhanced system variables include: AUTOSNAP, COPYMODE, DCTCUST, DCTMAIN, DCTMAINPATH, DIMTFAC, POLARADDANG, POLARANG, POLARDIST, POLARMODE, SNAPTYPE, and TRACKPATH.

Input Scale Factor works with All Commands
The Input Scale Factor specified in the General Configuration Options screen can now be applied to ALL distance inputs in the program, by specifying an "s" (for scale) suffix after the distance, for example 100s or 100S. Scaling was previously limited to only the MicroSurvey commands, but now also works with all CAD drawing, modification, and settings commands. Use the s suffix anywhere you can enter distances, including at the command line, in dialog boxes, and even when typing coordinate values like "100s,100s".
Inverse between Input Scale Factor and Output Scale Factor
The Input Scale Factor and Output Scale Factor fields on the General Configuration Options screen have been linked together, so you can now automatically set one as the inverse of the other with the press of a button.
Copy Output Scale Factor to Distance Labeling Scale Factors
A new Scale Factors dialog lets you easily configure all scale factors (Input Scale factor, Output Scale Factor, and five Distance Labeling Scale Factors) in one screen with no calculations required.
Automatic Blunder Detection
When your Input Scale Factor and Output Scale Factor values are not inverses of each other, or when the Output Scale Factor does not match your Distance Labeling Scale Factors, warning will appear to help you correct any potential issues.
Scale Factor Check on FieldGenius/RAW/RW5 File Import
When importing a RAW or RW5 file (including FieldGenius projects), the scale factors specified in the RAW file and in the General Configuration Options screen will be compared as a validation check, and if they do not match a Scale Factor dialog (see above) appears to help you correct any potential issues.
Scale Factor Setup on FieldGenius Export
When exporting a FieldGenius Project, a new option is available which will write the scale factor to the new project's raw file.
LISP Programming Extensions
Four new Lisp routines are available for your custom programming needs. New commands: (get_output_scale_factor), (set_output_scale_factor x), (get_input_scale_factor), (set_input_scale_factor x).

XML Import
A new XML Import command allows you to select any LandXML file to import the following data types from it: CgPoints (as Point Coordinates), PlanFeatures (as Smart Lines/Arcs), Parcels (as Lots), and Surfaces. New command: _LANDXML_IN
XML Export
A new XML Export command allows you to write a LandXML file containing the following data types from your drawing: Point Coordinates (as CgPoints), Smart Lines/Arcs (as PlanFeatures), Lots and Blocks (as Parcels), Surfaces (as Surfaces). New commands: _LANDXML_OUT and _LANDXML_OUT_RANGE
A new XML Export command allows you to write a LandXML file containing the following data types from your drawing: Point Coordinates (as CgPoints), Alignments (as Alignments). New command: _WRITEXML

Pick Text Labels for Lot Closures / Plan Check
Check your plan by using the new "Pick" buttons on the Lot Closure dialog, to select line and curve labels for calculating a closure based on the text labels.
Delete Lot Closures
A command is now available in the MsTools menu to delete existing Lot Closures from your drawing and database. New command: _MS_DEL_LOT_CLOSURE
Lot Closure Dialog Improvements
The Lot Closure dialog was cleaned up and made easier to use. Specifically...
The current entry field is now highlighted by a green box. This helps speed up keyboard entry when defining lots.
All data fields now immediately appear after selecting "Line" or "Curve", previously you were required to press Enter to make the next option appear which was not intuitive.
"Pick" buttons were added beside each distance and direction field, which allow you to select a text entity from your drawing to use for the lot definition.
"Pick All" buttons were added beside the Line and Arc fields, which allow you to select multiple text entities from your drawing to use for the lot definition.
"Swap" buttons were added beside each direction field, to reverse the direction of the currently displayed angle.
Removed Bearing/Azimuth and Feet/Metric controls, in favor of using the drawing's units settings as defined in the General Configuration Options dialog.
Removed OK buttons, in favour of having all fields immediately visible on the dialog.
Removed NW, NE, SW, SE quadrant bearing buttons, which which users found confusing and unnecessary.
Removed Zoom/Pan controls, which were previously necessary for older CAD engines, in favour of using real-time pan and zoom from your mouse.
Removed Current Coordinate text, which users found confusing and unnecessary. Current position is still indicated by an arrow icon in the drawing.
Realigned similar options to make the dialog more intuitive.

Complete Overhaul
There were so many fixes to the sewers commands, that it is practically a new feature. Sewers routines have not worked reliably for several versions.
Network Layout Updates
Sewer networks are now updated automatically when a structure is deleted, to keep the lines flowing past the deleted structure.
Sewer Browser Command
Our new Sewer Browser command lets you easily work with multiple network layouts. New command: _SEWERBROWSE
Query Structure Command
Our new Query Structure command lets you see information about any structures in your network. New command: _QUERYSTRC

New Survey Libraries
Two new Automap Libraries, Survey-M1 (Metric) and Survey-I1 (Imperial) have been provided which include an improved description list and an improved default layering structure.
Quick Posts with Wipeouts
New Quick Post blocks are included which use Wipeouts instead of a Trimming Radius to hide details behind/inside the blocks. You must load the new MSCAD_WIPEOUT.CSV AutoMAP Library instead of the default MSCAD.CSV AutoMAP Library to use the wipeout versions of the Quick Posts.
Symbol Librarian Posts with Wipeouts
New Symbol Library blocks are included which use Wipeouts to hide details behind/inside the blocks.
Misc Improvements
The ICI_AI and ICM_AI blocks (and their wipeout-version counterparts) were modified to remove extraneous points that were contained in the blocks.
