I want to create a semi-circle in the symbol editor. The help file is worthless in this regard and I couldn't find anything in the forum. It is damn sure not intuitive! Tom

Re: course of HOWTO build models like (sanken) STR-A6100
Hi, Tamura Kentai: The example is NOT suitable to used in the real world, it's just a demo to see if the STR-A6100 could behave well. It's absolutely not suggested to use it in real world. Especially,
