Hello, I have been looking to build a GM 6+1 trigger to suit the Delco D1927a ignition module in autocad. What a pain that software is! I found this project and it looks fantastic for this type of work. I've had a bit of a play and am wondering what it would take to achieve this pattern: http://www.megamanual.com/ms2/GM_DIS.htm

I think the pattern needs to be inverted, so notches inward instead of teeth outward. Then there needs to be a way to add the extra reference tooth, rather than remove one.

If you are using the fancy curved tooth style the generated image currently does not curve the teeth on either side of that area. However it's very easy. If you have generated the Text Legend (by clicking the check box) you should see near the bottom Tooth Rounding Radius which is what can be used with QCAD's rounding command (RN). When you select the rounding command (RN keystroke) you will see a prompt in the upper toolbar for a radius. Use the Tooth rounding Radius as that value. You may have to remove a few of the digits from the number as the entry may not like all of them. For example -

Tooth Rounding Radius : 0.19840775348828485

You should enter something like : 0.19840775

Note : It's important to use the Tooth Rounding Radius if you want to have all the teeth match. This can also slightly affect wheel balancing if not done (Very slightly).

Due to updates in QCAD (3.26+) the RTextEntity function now supports the width attributed. The original setting prior didn't seem to do anything so was set at 1.00 which is not incorrect. Should be set to 0.0 for no wrap.
