Version 1.1.0

•  Thick Face tool
•  Mesh tool
• color indication of material names inside material drop-down lists
• drop-down lists and radio buttons in 'Properties' dialog (for such properties as surface materials, shape type etc) instead of simple input fields
• tools, which have more, than one contour ('Beam', 'Slope', 'Mesh') now have 'nodal points' active at startup in order to be ready to draw an object right after dialog activation

• minor fixes of 'Opening' tool and opening entity (fixes related to custom contour, manual grid lines, non-zero rotation angle of customly shaped opening, precise joint type)
• 'Label Template' dialog: assigning a name to a newly created or existing label template is fixed
• entered offset value after dragging of an object now always takes effect even in case of hovering over any adjustment point during offset value entering
• tool dialog minor appearance fixes: animation of tool state icon is fixed, styling of a warning about wrong numeric value is improved
• java-script warnings during 'Help System' browsing removed

Version 1.2.0 and 1.2.1

• this version introduces grid meta-object*, which can be created using  Grid tool
  
  *) Meta-object may not represent directly any real-life element of a building or structure (such as wall, column, beam etc), but it can be used to describe somehow more abstract geometric level of a structure. BIM objects, which represent real-life elements, can be attached to meta-object as sub-objects. So complex structure, which consists of attached sub-objects, can be created in a batch manner according to geometric rules described by meta-object. You can take a look at Grid tool usage samples here >>
• sub-objects feature implemented for Mesh tool either
• Beam tool is enhanced with "Profile Alignment Restriction" setting, which contains the following options:
  •  vertical alignment restriction
  • horizontal alignment restriction
  • no alignment restriction
  (the main reason for this new feature is to avoid profile rotation about curved axis by switching to vertical or horizontal alignment, it may be useful for creation of a spiral ramp surface for example)
• Thick Face tool is enhanced with "Thickness Measure Direction" setting, which contains the following options:
  •  distance direction
  •  offset direction
  (this feature may be useful when using thick face as a sub-object of any meta-object)

• calculation of reporting values of a wall object, which was cut to slope object and contain openings, fixed
• java-script part minor improvements
• explanation about undoing results of LSS Arch Tool processing added to Help system
• animation of Mesh, Thick Face and Grid tool processing added to Help system

Version 1.2.2

• calculation of offset of beam sub-objects attached to grid object which has clipping contours fixed
• z-coordinate of clipping contours of a grid object now made equal to z-coordinate of a grid origin (i.e. clipping contour-lines now attached to the bottom of a grid object)

Version 1.2.3

• ability to make curved segments by right-clicking on a segment middle grip and choosing segment type from a context menu
• auto-alignment of ends of walls and beams to a nearest face (this feature is made enabled by default within global settings)
• ability to adjust wall's and beam's ends alignment manually by moving start/end segment points (it is necessary to turn off auto-alignment of ends using 'Properties' dialog in order to be able to adjust alignment manually)

• problem with a custom profile of a beam tool fixed (appeared in ver. 1.2.0)
• "Mesh" tool now generates cleaner side surface of a mesh, which has a clip contour (skipped faces could appear in previous versions)
• material selectors within 'Properties' dialog display materials now right after dialog launch if some LSS Arch object(s) was (were) selected before it (previously it was necessary to deselect and select an object again in order to refresh contents of material selectors)
• alignment of an opening preview gismo when "cut opening" mode is active is now fixed (previously alignment was incorrect in one particular usage case: when some existing opening was picked (selected) while tool was active and then "cut opening" mode was activated right after existing opening picking)
• changing of properties of selected LSS Arch objects, which were copied somehow using SketchUp's native tools (i.e. were not originally created using LSS Arch tools), now comes more properly (previously changing of any property caused resetting of a "level" property of copied objects, so it was necessary to rebuild copied objects using "Rebuild" command before re-adjustment of properties in order to refresh "level" property of each copied object according to its actual position in an active model)
• "Labels" context menu fixed
• profile alignment restriction now works when beam's contour is closed too
• restoring of roll-groups' states when dialog auto-size is disabled is fixed

Version 1.3.0

• new meta-object added:  Contour object
  
• "blob" body type added to mesh object
• ability to generate isolines/horizontals added to mesh object
• ability to attach sub-objects to a beam object implemented
• "divided" segment type added (in addition to "arc" and "curved" segment types introduced in version 1.2.3)

• minor CSS formatting fixes (affect alignment of sub-object bands when dialog size is set to "standard")
• error message when clicking "Select Similar" speed-button of "Properties" dialog when no arch objects selected fixed
• reading of sub-objects now works with pre-selection of meta-objects too (previously it was necessary to pick meta-object while corresponding tool is active in order to read sub-objects)
• situation when 'Contour Line' option of 'Sub-object Position Options' is set to 'contour' and only last level selected is now fixed (previously sub-objects were discarded in case of such combination of options)

Version 1.4.0

• ability to add and load shape presets added to beam and column tools
• ability to add and load tool presets added to complex tools like grid, contour, mesh, opening and beam
• set of utilities added:
  • Save LSS Arch Objects
  • Restore LSS Arch Objects
  • Convert Imported IFC Objects
  • Set IFC Attributes
  • Explode Down to LSS Arch Objects
  • Explode Down to Faces

• ability to use iso-lines (horizontals) of a mesh object for sub-object's generation implemented
• custom origins added to a grid tool (similar to a contour tool)
• "Layers" dialog added
• ability to set a custom layer for an object is implemented
• since this version extension is made compatible with OSX
• new setting "Lock level of an object" added, which allows to keep level specified in a tool dialog while drawing of such objects like wall, slab, slope and column

• calculation of a volume of a thick face object is fixed
• animation of an opening's shape change is fixed
• animation of beam's profile change is fixed
• a rare situation, when opening could jump to another wall/slab, which already has other openings, right after using adjustment points for changing its height/width is fixed now
• profiles of a custom shape of beam and column sub-objects now fixed (custom shape switched to default during readjusting of sub-object's settings in previous versions)
• profile preview of a column sub-object now refreshes as expected according to shape type changes
• shape changes of beam and column sub-objects now take place faster (animation of changes is now supressed for settings dialogs of sub-objects)
• profile preview of a beam tool now displays profile shapes, which have curved segments, correctly
• logic of picked faces, which have curved parts, is restored (since ver. 1.2.3 curved parts could loose smoothness after rebuild)
• logic of auto-soft and auto-smooth is restored
• support of curved segments added to sub-objects
• displaying of cubic units in dialogs is fixed
