My 5 cents worth first nod684
- Its easier to do ddd.mmss and convert only need 1 getreal.(setq DEG (getstring "\nType the degree: ") minx (getstring "\nType the minute: ") SEC (getstring "\nType the second: "))(setq DEGbrg (getreal "\nType the degree DDD.MMSS : ")(setq DEG = You take the DEGbrg fix, subtract *100 fix subtract divide 60 subtract divide 3600 so end up with decimal angle. Just need your units variables set correct. ) No cad at moment.
2nd part pick line near start end of new line this returns exist angle then you can enter swing angle which is added to existing line angle and a polar gives new pt and so on. You would have an option like "pick start line or new pt pick blank screen or press enter so then asks pick start point with true bearings entered. You may need a back bearing entered as well depends what BRG's you are entering. |
