Techne (R) CAD/CAM Files

These versions are still an alpha.  Anything related to help files, instruction, tips are out of date, missing, etc.

Version 1.0.0.9

Previously the order of making cuts was to do all normal cuts first, then any drill type cuts no matter how they were ordered by the user.  Now the order will be correct.

Slight change in file format, designs using previous versions will not work in this version.

Version 1.0.0.8

File format for part and tools has changed

Redesigned the toolpath point class to hold data with instructions to set spindle speed, type of milling.  Previously the toolpath group class held this info.

Updated feed rate computation method for 3D movements.

Changed ramping angle from being hard coded, so being user setable on a tool by tool basis.

Change toolpath start method to have a tool level default value instead of machine level.

Changed some of the startup GCode commands.

Will now turn off spindle if a tool specifies 0 RPM speed, used in drag operations.

All ASSERTS in the toolpath generation will not fire if the abort flag is set.

Generation fo ZigZag toolpath allocated array sizes incorrectly.

Computing the time for machining was wrong when the speed units used seconds.

Version 1.0.0.7
The part preview will now utilize all cores on multi-core systems to render.  Only doing it on preview, for real toolpath creation will continue to use a single thread.

Repaired errors in thread termination routines.

Now test for multi-core capability, if found the start of preview rendering will occur sooner.

Found possible error when using shared pointer accross threads, fixed.

Converted all dialogs that self destroy to Factory creation model.

Removed all references to AfxEndThread (turns out has significant memory problems).

Moved critical section variable to application object instead of document space.

Moved many objects that use shared pointers to be on heap instead of stack.

Using std::shared_ptr instead of boost::shared_ptr

When creating data for a threaded toolpath, now clone cuts and send that instead of polygon representations of cuts.

Selecting a round part geometry caused error.

Added abilty to turn off or select low quality previews.

Version 1.0.0.6
Finished implementing drilling type cuts.

Version 1.0.0.5

Adds a drilling capability that is not fully implemented.  Specifically saving/loading of designs with a drill cut is not tested, but generating toolpaths should work.  There was a reported bug creating an ASSERT when trying to save a toolpath that hopefully has been fixed.
