Extend your AutoCAD LT productivity



LT Extension add-on


LT Extension is an add-on application by CAD Studio (Xanadu) which adds a number of useful functions to your AutoCAD LT (or AutoCAD) toolbar. LT Extension is compatible with AutoCAD LT98, LT2000, LT2000i, LT2002, LT2004, LT2005, LT2006, LT2007, LT2008, LT2009, LT2010, LT2011, LT2012, LT2013, LT2014, LT2015, LT2016 and LT2017, with any language version of AutoCAD LT (and full AutoCAD). Both 32-bit and 64-bit versions of AutoCAD LT are supported in Windows XP, Vista, Win7, Win8/8.1 and Win10 (32/64).

Installation


For AutoCAD LT 2004, LT 2005, LT 2006, LT 2007, LT 2008, LT 2009, LT 2010, LT 2011, LT 2012, LT 2013, LT 2014, LT 2015, LT 2016 and LT 2017 you can use an automatic installation routine LTExtensionSetup.exe.

In other cases copy all files from the distribution archive to your AutoCAD LT support directory (e.g.
C:\Program Files\AutoCAD LT 2002\Support or
C:\Documents and Settings\user_name\Application Data\Autodesk\AutoCAD LT 2010\R15\enu\Support or
C:\Users\user_name\AppData\Roaming\Autodesk\AutoCAD LT 2014\R20\enu\Support).
IMPORTANT (first time only): Launch AutoCAD LT and enter the _MENULOAD or _CUILOAD command. Load the LText.mns or the CUIX ribbon as a partial menu (do not rename it). LT Extension toolbar should appear in your AutoCAD window. Place it (or dock it) anywhere you want. This is only a first time operation - the toolbar will load automatically in all your subsequent AutoCAD LT sessions.

Usage


The application consists of a toolbar containing several flyouts with command groups. You can click the last button (with white rectangle) in the flyout to display a separate toolbar for the command group.

The first part of the LT Extension toolbar contains layer functions.

  • Freeze by pick - freezes the layer you select by picking an object laying on that layer
  • Off by pick - switches off the layer you select by picking an object laying on that layer
  • Isolate layer - freezes all layers except that selected by picking an object laying on that layer (only objects laying in this layer will remain on the screen)
  • Delete layer - deletes all objects(!) laying in the layer you select by picking an object laying on that layer
  • Thaw all - thaws all layers (e.g. for returning from the Isolate layer or Freeze xref commands)
  • Move to current layer - move (change) selected objects to the current layer
  • Move to selected layer - move (change) all objects in the selected layer to the new selected layer
  • Freeze xref layers - freezes all xref layers
  • Explode layer - explodes all explodeable objects in the layer you select by picking (pick a sample object)
  • Bring layer to front - brings forward (order) the objects in the layer you select by picking

The second part of the LT Extension toolbar contains drawing, dimensioning/ID and text functions.

  • Dim Arc length - dimensions the selected Arc, displays arc length (unlike the _DIMANGULAR command), use DIMARC in LT2008+ (number of displayed decimal places depends on Units setting, see Advanced formatting in Readme)
  • Point ID - labels selected point with leader and its coordinates X/Y (northing/easting) (number of displayed decimal places depends on Units setting, see Advanced formatting in Readme)
  • Point ID XYZ - labels selected point with leader and its coordinates X/Y/Z (3D position) (number of displayed decimal places depends on Units setting, see Advanced formatting in Readme)
  • Area label (obj) (area text) - measures and labels a closed area (border must exist) (number of displayed decimal places depends on Units setting, see Advanced formatting in Readme)
  • Area label (pt) (area text) - measures and labels a closed area (defined by an internal point) (number of displayed decimal places depends on Units setting, see Advanced formatting in Readme) - metric and imperial versions
  • Framed odkaz - draws a leader with framed single-line text
  • Dim in->mm - converts selected dimensions in inches to metric dimensions mm
  • Dim1 off - suppress first extension line
  • Dim2 off - suppress second extension line

  • Cross - draws an infinite cross in picked point - rays in X/Y axes
  • Horizontal line - draws an infinite horizontal line (X)
  • Vertical line - draws an infinite vertical line (Y)
  • Arc by length - draws an arc of given length

  • Framed text - inserts an arbitrary text with rectangular frame (text properties depend on the current dimension style - see _DIMSTYLE)
  • Text along - rotates selected text along selected line - select the text, then the linie
  • Autonumber - places a series of text with autoincremented numbers (text centered on pick points) (text properties depend on the current text style - see _STYLE)
  • Autonumber edit - edits a series of texts to autoincremented numbers
  • Autonumber block - edits a series of blocks (attributes) to autoincremented numbers
  • Autonumber reset - resets the number for autonumbering (00 or NN)
  • Drawing name - places the current drawing name (no path, no extension) in the drawing as Text entity (text properties depend on the current text style - see _STYLE)
  • Comment object - adds a persistent comment to any drawing object(s), comment is displayed when you pause cursor above an object (n/a in LT98)
  • Text (height=2) - draws single-line text with height of 2 times the DIMSCALE setting
  • Text (height=5) - draws single-line text with height of 5 times the DIMSCALE setting
  • Text (height=10) - draws single-line text with height of 10 times the DIMSCALE setting

  • Insert image - inserts a raster image (path set textually in LT2007/2008, uses internal command in LT2009)
  • Insert 10 images - inserts a template with 10 raster images (paths set textually in LT2007/2008)
  • Non-rectangular viewport - inserts non-rectangular viewports (delete unused)

  • Calculator - displays a calculator (n/a in LT98)
  • Calculate-Add - adds numbers (in any AutoCAD LT command, incl.coordinates - e.g. a LINE from [0,0] to [123+456,789*3] )
  • Calculate-Subtract - subtracts numbers (in any AutoCAD LT command, incl.coordinates)
  • Calculate-Multiply - multiplies numbers (in any AutoCAD LT command, incl.coordinates)
  • Calculate-Divide - divides numbers (in any AutoCAD LT command, incl.coordinates)

The third part of the LT Extension toolbar contains editing functions and utilities.

  • Report coordinates - exports X-Y-Z coordinates of the selected entities (Point/Shape/Insert/PLine) to an external text file (comma delimited)
  • Go 2D - moves all selected objects to 2D - to Z=0
  • Segment curve - converts selected arc or polyline to line segments with a given length, simplifies (weeds) complicated polylines
  • Explode spline - converts selected spline object to a segmented line
  • Move to PS - move selected objects from the modelspace to the paperspace (layout)
  • Background color - toggles background color in drawing modelspace (black/white)
  • Reset environment - resets the AutoCAD settings to predefined default values (script, can be customized)

The fourth part of the LT Extension toolbar contains web links.

  • CAD Forum - browse to CAD tips on the CAD Forum web site - www.cadforum.cz
