2018-07-10 Build 724
Adressed extra error control for non attribute blocks in draw from coordinates, block along path.

2018-04-24 Build 722
Problem with Report files
"Can't find report file" message. The solution by providing a new location for reportfiles folder (settings form) works when you don't have write access to CadTools executable folder. In the settings form you provide a new path to a folder of your own and that works! The problem was that CadTools didn't save the setting when you closed.

(20
12-
07-
15 Build 670)
Fixed: Some commands in CadTools where designed to remain active until user hits ESC. This behavior didn't work as planned on localized versions of AutoCAD, there were no other options than terminate CadTools when using these commands (endless loop). The solution for this problem was to add a question on the command line "Continue this command? [Yes/No] <Y>:"
This reduces the simplicity while using these commands but I couldn't find a better solution.

(20
12-07-05
Build 669)
Fixed: "Match Blocks with Lines", Overflow while evaluating huge models fixed

(20

Fixed: Create Surface Command: The option "Set Duplicate Tolerance" didn't work as designed. This option has been changed to reduce decimals only. Filter Object Elevations is now applied before the user select objects and the result of the filtering is displayd as reducing of "Number of Points". Triangulation halted and reported duplicate points on huge dataset, this has been fixed. Also added info about triangulation time, this information is displayed in the status bar when all is done (saving or plotting)Fixed: Pasting more then 32 000 rows from Excel into "Draw from Coordinates" resulted in a error, this has been fixed.

2-01-16
Build 662)
Fixed correct number of decimals is shown in "Volume by Elevation". The number of decimals is now always same as in your interval even if you type ".10"
Some users have problems canceling commands with ESC. I can't promise this is fixed because I can't reproduce same
behavior myself. I've done some changing in the code, hope it helps.

(2011-12-31 Build 661)
"Check for updates" is rewritten and implemented.
Fixed bug: Vehicle turning command. Minimum turning radious displayed incorrect value for units other than meters(2011-12-16 Build 660)

10-30 Build 657)
Fixed a bug in "Annotate Cross-Section" pasting table to a nonexisting layer didn't work.
Added multiple axels for some vehicle types in the drawing output for Vehicle Turning. There is no option for the user to manipulate this

(2011-10-23 Build 654)
Added Layer Name same as text in Draw from Coordinates (Text at Point). This option is useful if you get a file with coordinates and a tag (text). You can easily create layer names same as the tag and draw the text at that layer. (2011-09-05 Build 653) Fixed: Issue with saving edited triangles, CadTools always claimed: "Couln't find any CadTools triangles to save (no matching X-data)". Changed: "Tranverse 3D lines between 3D Polylines" has been changed. If elevation difference between the polylines was huge the offset din't work as expected. Offset was set to follow the transverse line direction, now it is set to follow horizontal direction. Changed: "Polyline area" command. Added messagebox with a warning if you have 3DPolylines in your selection.

(2011-09-01 Build 652)

Fixed another bug in "Track station and offset from polyline". Incorrrect calculation of stations in arc segments (sometimes)

(2011-08-31 Build 651)

Build 643)
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".

(20
11-04-17
Build 641)
Fixed: Start with major ticks in "Slope and Road Signs" worked in opposite way

(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)

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.

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.

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.

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.
