Hi, Thanks for all the info!
In actual fact, the angle is calculated starting from north as 0 degrees (as in Normal Compass bearings) Regards Marius -----Original Message----- From: Peter Horsb�ll M�ller [mailto:[EMAIL PROTECTED] Sent: 02 July 2003 09:58 To: 'Lars V. Nielsen'; Marius van Wyk Cc: [EMAIL PROTECTED] Subject: RE: MI-L Creation of lines from table with points and angles/bear ing And if your angle is in degree you can multiply the angle with 0.01745329252 to get the value as radian: 4.. Update myTable Set OBJ = CreateLine(myXCol, myYCol, myXCol + Cos(myAngleCol * 0.01745329252) * desiredLength, myYCol + Sin(myAngleCol * 0.01745329252) * desiredLength) But of course this also raises the question of how your angle is calculated ? 1. Closewise from west ? 2. Counter clockwise from east ? 3. Counter clockwise from north ? 4. Clockwise from north ? 5. Is there more obvious ? As I remember the formula mentioned above only works on the second.
