Fixed a bug in "Annotate Cross-Section" Annotation didn't work with only one item in the list.
Added a "Check for updates" once a day when starting CadTools, if there is a update available CadTools will inform the user.

(2011-11-27 Build 658)
Added support for a number of drawing units in the Vehicle simulation command. The code base in this part was based on meters. Using units smaller than meters would result in slow performance. This is fixed now.

(2011-08-29 Build 650)
New command: Delete Points, Circle and Text In/outside polygon. This command can be found in the "Miscellaneous menu"

Fixed: "Annotate Block elevations". Some bugs in text height, added number of decimals.
Fixed: "Stationing", sometimes the last station was placed elsewhere (this bug has been around for a while).
Fixed: User selection for current AutoCAD-version wasn't saved correct, this could cause problems when using multiple versions.
Fixed: Smoothed polylines isn't a supported linetype in CadTools! I've tried to manage them but I gave up. I'm sorry but the solution is to change the polyline property "Smoothing" to none before executing any CadTools command on the polyline. User gets a message informing of a "Unsupported line".

(2011-04-17 Build 641)
Fixed: Start with major ticks in "Slope and Road Signs" worked in opposite way
Fixed: "Slope arrows on 3D lines" didn't work as planned

Changed Freeze X-ref by layer to work without stopping (ESC to Cancel) Polyline length and area calculations now has separate buttons for sending result to Excel

(2010-01-17) Added support for 64-bit AutoCAD.
New command: Station equations” is a simple method to deal with railroad alignments (kilometers can be shorter or longer than 1000 meters). This method can be used in with the “Draw from coordinates” to put text or block at correct station. To make this method possible some changes has been done to the "Text and Block Station/Offset from Polyline to Excel" command.

New command:"Annotate Cross-Section/Profile Slope” is a new handy command for annotation of sections and profiles.
New command:"MText Color override remover”
Fixed CadTools SpreadSheet, increased speed while updating.
Added offset side to the: "Text and Block Station/Offset from Polyline to Excel" and some other stuff.

Added offset side to the: "Text and Block Station/Offset from Polyline to Excel" command (Miscelanneous). Fixed CadTools SpreadSheet, increased speed while updating.
New Command: MText Color override remover.

Fixed minor bugs and added rownumbers to CadTools SpreadSheet. Extended "Draw from Coordinates" with a command to draw text at polyline station and offset. Added new command for registered users; "Text and Block Station/Offset from Polyline to Excel", a command that process multiple block or text objects in a drawing. Result contains information of blocknamne or text string, station and offset from selected polyline. This command can be found in "Miscellaneous"

(2010-01-11) Fixed bug in export polyline coordinates to SpreadSheet

(2010-01-09) Added a solution for users that don't have Excel installed. All "Export to Excel" can now be targeted to a internal SpreadSheet window an then copied to Windows clipboard.
Extended "Layer Freeze by object" with some missing functionality. Fixed Simplify 3Dpolylines, closed polylines didn't work.

(2009-11-09) Fixed bug in "Insert Line-aligned text", using the command on 3D polylines didn't work as expected.

(2009-11-09) Added column for block rotation in "Draw from Coordinates". This extra column makes it possible to use a time saving procedure for inserting block at start and endpoints of hundreds of polylines. The procedure is described in CadTools forum (Tips and Tricks section)

(2009-11-01) Drag'n drop surface files from Explorer to CadTools is now supported. Added a new button for scaled length and annotation in one step (Slope Mode).
"Draw from Coordinates", "Block at Station/Offset from polyline" now support 3D-polylines (how could I miss that?). Also added a setting for Block elevation relative polyline elevation in the same command.
In the settings user can set a folder for reports and temporary files. This can solve problems with read and write access under Vista.

(2009-10-15) Minimize property for all forms. Region area to Excel (miscellaneous). 3DSolid volume to Excel (miscellaneous). Rotate annotation for respond label (Mode Slope), rotation angle is found in settings.

Position marker option for the "Table Edit polyline" command.

(2009-09-06 Build 532)
Fixed bug in "Stationing", turned off support for polylines with arcs in "remove duplicate points"

(2009-09-03 Build 531)
Added text rotation to "Draw from coordinates"

(2009-09-03 Build 530)
Fixed a bug in "Place Sloped text", added rotation and layer name to "Export text to Excel"

(2009-08-16 Build 529)
Added vertical text with layer name for reference lines in Cross-sections, great for annotation of borders n cross-sections. Added "Line start at:" in the Draw from coordinates, block at station. Useful if alignment station is other than zero.
Updated reference manual!

(2009-07-28 Build 528)
Fixed a bug in the "Place sloped text", problem due localization (decimal separator)

(2009-07-28 Build 527)
Fixed a bug in the Create 3D alignment (Surface profile). If user picked left vertical frame as elevation reference the resulting 3D line (alignment) was wrong. Similar command in the Profile polyline worked fine.

(2009-07-24 Build 525)
Fixed a bug in the Join 3Dpolyline command. Changed behavior of the "Create 3D alignment" now you get a question if you want to keep the unprofiled line in the drawing or replace it with the profiled line. Changed the triangulation command to create better triangulations, the breakline part has been rewritten and seems to work more stable now. Added support for booth 3Dpolylines, polylines and lines in the "Multi offset command"

(2009-07-10 Build 524)
The Trickle and Trickle All command (Edit/View surface, Tools) wasn't doing the job correct, sometimes the trace path stopped. This has been corrected in this update. I was testing some refinement for the triangulate algorithm and discovered that sometimes the algorithm could result in overlapping triangles, this is corrected in the update (no refinement is implemented). Added "Zoom to Surface View" in the "Edit/View" command, located under "Surface". This zooms AutoCAD's window to fit the loaded surface boundaries.

(2009-06-30 Build 520)
Added new command. Under Miscellaneous you find a "Dist" command for horizontal length and slope that can be used with Autocad's snap on. Fixed a bug in the "Table edit polyline". Added "Northing/Easting" in column headers in the "Draw from coordinates" command.

(2009-06-19 Build 514)
Made som enhancements to constrained triangulation. Fixed problems with "Create longitudinal features" in surfaces with holes. Added option to simplify (weed) longitudinal fetures.

(2009-06-13 Build 511)
New command for calculating Cut and Fill and component areas in cross sections. The command work for all kinds of cross sections not only those generated by CadTools and it will manage exaggerated scales. The result can be annotated as a table of points containing offset and elevation and a cut and fill area. The table can be useful as input in other software (Pizer EARTH's Cut & Fill Calculator)

Surface profiles now support crossing lines similar to the cross-section "Display references". The profile plot can be annotated with major and minor ticks and labels, you can annotate surface elevation for minor stations. A nice feature is displaying projected lines in the profile, you pick 3D polylines in the drawing and then CadTools displays it as a projection. This can be useful in many cases, as an example you could offset a couple of lines from the profile and drape them on the surface and finally display them as projected reference lines. By this you can get information of the surface elevation at any offset from the profile line.

New command, "Export Hatch area to Excel" useful for quantity calculations
New command, "Place sloped text" makes it easy to place elevation text based on a basepoint and a slope.
