---- Hallo every body, I will be a new guy here. I start this page as my page. I will update it soon. 30.08.2007 ---- I can't wait anymore. I want say some thing right now with my poor English. I needed a GUI for my work half year ago. So I was such a luck guy than I find Tcl/tk, and I find here. I have learned a lot, and I want say thank you all. I thought it is to hard to find something here what you need right now..... but more importent: "I feel it free to see, to say, and to show something." Something help me a lot. I have now something to show you, my first program. I call it "SD2007". With "SD2007" you can calculate the forces (N,Q,M) for a structure.

Because I study right now in Stuttgart,Germany. I hope I could translate it later. I keep on doing it for the following one year. (until I finish my study) I will try 3D with Tcl/tk later. I am glad to hear some opinion, some advise. Finaly, thank you for reading this. And I post my code here, I think I could and will show something. I think it help somebody.
