NCPlot v2.21 Release Notes
September 12, 2010


Improvements

The tools "Break Arcs Into Lines" and "Break Arcs at Quadrants" now support both absolute and incremental endpoints as well as center points.

The tool "Break Lines Into Segments" now supports both absolute and incremental endpoints.

When the subprogram setup is set to warn if sub not found there is now an option to cancel program execution when the message appears.

Enjoy!

Hi Scott,
Can you take a look at the following program snippet and check if it is ok. I am toying around with scaling and rotation using G68 and G51, havent yet tried it on a machine. I was using NCPlot for the development of this as there will be variables used, i am getting strange results from the plot, although i have not used these codes together on a machine so am unsure if my syntax is correct or if ncplot is correct.

Keith,

This appears to be a problem in NCPlot. Something is going on with the arc commands when both scaling and rotation are applied at the same time.

Thanks,
Scott

Tried to download the program and it sais the installer is corrupted...

There's seems to be a bug in the rotary work . Where this code is supposed to make the 4th axis "A" rotate 2 revolutions. However it only plots 1 revolution.

Your help would be greatly appreciated.

Bknight,

This does seem to be a bug. NCPlot is calculating the rotary endpoint and does not account for multiple turns. I've got this on my bug list.

Thanks,
Scott
