Version history (up to 0.8.0)

Since I removed the changelog from the script file itself - here's the original text up until version 0.8.0.

v0.8.0

  • Volume calculation

v0.7.15

  • Measurement of face normals by TNae + extended to cover all cases.
  • Grouped measured values inside boxes.

v0.7.14

  • Fixed matrix calculation order.
  • Replaced region3d_get_2d_coordinates with location_3d_to_region_2d" from bpy_extras.view3d_utils.

v0.7.13

  • Moved property definitions to registration function.
  • Changed automatic callback adding to manual, the current API doesn't seem to allow this top be automatically yet.
  • Various API fixes.

v0.7.12

  • Moved setting of properties to callback function (it is bad practise to set it in the draw code).
  • Fixed distance calculation of parented objects.
  • API change: add_modal_handler -> modal_handler_add
  • Regression: Had to disable area display for selection with more than 2 meshes.
  • Fixed Local/Global vert-loc calculations in EditMode.

v0.7.11

  • Applied patch by Filiciss Muhgue that fixes the text in quad view.

v0.7.10

v0.7.9

v0.7.8

  • Various Py API changes by Campbell ...
  • bl_default_closed -> bl_options = {'DEFAULT_CLOSED'}
  • x.verts -> x.vertices
  • @classmethod def poll(cls, context)
  • No "location" in bl_info->name
  • bl_info->api

v0.7.7

  • One more change to the callback registration code.
  • Now it should finally work as intended.

v0.7.6

  • API changes (r885, r886) - register & unregister function

v0.7.5.3

  • Small fix for bug in v0.7.5.1 (location was off when object was moved)

v0.7.5.2

  • Changed callback registration back to original code & fixed bug in there (use bl_idname instead of bl_label)

v0.7.5.1

  • Global mode is now taking rotation into account properly.

v0.7.5

  • Fixed lagging and drawing issues.

v0.7.4

  • Fixed the modal_handler_add and callback_add code. Thanks to jesterKing for pointing that out :-)

v0.7.3.1

  • Fixed bug that made all lines in Blender stippled :-)

v0.7.3

v0.7.2

  • Merged changes from trunk (scripts_addons r847):
  • obj.matrix -> obj.matrix_world
  • vert.selected -> vert.select
  • face.selected -> face.select
  • bl_info: warning, wiki_url, tracker_url
  • removed __bpydoc__
  • Use fontid=0 for blf functions. 0 is the default font.

v0.7.1

  • Merged changes by Campbell:
  • Fix for API change: Collections like context.selected_objects no longer return None for empty lists.
  • Update for mathutils, also stripped some redundant conversions (Mostly "Vector()" stuff)

v0.7

  • Initial support for drawing lines. (Thanks to Algorith for applying my perspective_matrix patch.)
  • The distance value (in BUs) is also drawn in the 3D view now.
  • Also fixed some wrong calculations of global/local distances.
  • Now it's really "what you see is what is calculated".
  • Use bl_info for Add-On information.
  • Use "3D View" in category & name
  • Renamed reenter_editmode to view3d.reenter_editmode.
  • Renamed panel_measure.py into space_view3d_panel_measure.py
  • Active object is only used for edit-mode now. Measurement with exactly one sel. (but not necessarily active) object now gets the obj via the sel-object array.
  • API change Mathutils -> mathutils (r557)
  • Deselecting 1 of 2 objects now works correctly (active object is ignored).
  • Force a redraw of the area so disabling the "measure_panel_draw" checkbox will clear the line/text.
  • Only calculate area (CPU heavy) if a "area" checkbox is enabled.

v0.6.4

v0.6.3

  • Added register & unregister functions.

v0.6.2

  • Fixed precision of second area property.
  • Reduced display precision to 5 (instead of 6).
  • Added (commented out code) for shortcut [F5] for updating EditMode selection & calculation.
  • Changed the script so it can be managed from the "Add-Ons" tab in the user preferences.
  • Corrected FSF address.

v0.6.1

  • Updated reenter_editmode operator description.
  • Fixed search for selected mesh objects.
  • Added "BU^2" after values that are not yet translated via "unit".

v0.6

  • Fix: Removed EditMode/ObjectMode toggle stuff. This causes all the crashes and is generally not stable.
  • Instead I've added a manual "refresh" button.
  • I registered a new operator OBJECT_OT_reenter_editmode for this.
  • Use "unit" settings (i.e. none/metric/imperial)
  • Fix: Only display surface area (>=3 objects) if return value is >=0.
  • Minor: Renamed objectFaceArea to objectSurfaceArea
  • Updated Vector() and tuple() usage.
  • Fixed some comments.

v0.5

  • Global surface area (object mode) is now calculated as well.
  • Support area calculation for face selection.
  • Also made measurement panel closed by default. (Area calculation may use up a lot of CPU/RAM in extreme cases)

v0.4.1

  • Various cleanups.
  • Using the shorter "scene" instead of "context.scene"
  • New functions measureGlobal() and measureLocal() for user-friendly access to the "space" setting.

v0.4

  • Calculate & display the surface area of mesh objects (local space only right now).
  • Expanded global/local switch.
  • Made "local" option for 3Dcursor-only in edit mode actually work.
  • Fixed local/global calculation for 3Dcursor<->vertex in edit mode.

v0.3.2

  • Fixed calculation & display of local/global coordinates.
  • The user can now select via dropdown which space is wanted/needed
  • Basically this is a bugfix and new feature at the same time :-)

v0.3.1

  • Fixed bug where "measure_panel_dist" wasn't defined before it was used.
  • Also added the distance calculation "origin -> 3D cursor" for edit mode.

v0.3

  • Support for mesh edit mode (1 or 2 selected vertices)

v0.2.1

  • Small fix (selecting nothing didn't calculate the distance of the cursor from the origin anymore)

v0.2

  • Distance value is now displayed via a FloatProperty widget (and therefore saved to file too right now [according to ideasman42].
  • The value is save inside the scene right now.)
   Thanks goes to ideasman42 (Campbell Barton) for helping me out on this.

v0.1 - Initial revision. Seems to work fine for most purposes.
