However the way it is done right now the cutter is tested against the whole infinite plane containing the facet. This way the edge and vertex tests are needed. Dan: I will make some obvious improvements and iron out a few bugs, after that it would be nice to try to integrate with HeeksCNC Michael: if there was a way to test the cutter against only the facet of the triangle then that would indeed be enough.

It has a python interface, so it is perfect. Is it available to download? HeeksCNC currently uses "kurve" 2D profile offsetting, from Geoff, who was my boss at Camtek UK. "libarea" for pocketing, based on some GPL polygon boolean code "libactp" for adaptive roughing. "pycam" for 3D machining. We would love something to try to replace pycam, it is very slow. Dan. Anders,

What I do not understand, why are you testing against edges and vertices? The triangle defined by these vertices and edges should be enough? Maybe a stupid question, but I do not get it.

"... I can tell you that the design hull depth for PIKANTO is 59.3 mm and, because the fin box cavity occurs at the deepest point, and the deepest part of the hull moulding is cut away 5 mm each side of the centreline, the deepest part of the actual hull is only 59.1 mm below the waterline. So we have a 0.9 mm margin for error in the construction of the boat. Alternatively, if the boat is built to exacting standard, some 120 grams additional weight could be added before there is a problem with the boat being over depth.

Do you apply glass tape through the apertures in the deck moulding ? Congratulations on a fantastic website... Andy Anders,

Craig Smith advised me of this. It is manufactured here in Australia. Buying a 1 litre pot, with 50 ml hardener, will mould over 50 bumpers. We normally use 15-20 ml of part A and just 1 or 2 drops of hardener. Cure time ranges from 15 to 30 minutes, dependent on ambient temperature. Of 2 different hardness types, I chose the firmer compound. This is very white in colour, and doesn't require extra pigmentation. It does not require any release agent, it simply peels out.
