အခု ကၽြန္ေတာ္တို႔ Alignment ႏွင့္ Direction တခုဆံုရာမွာ ပြိဳင့္ဖန္တီးတာကို ေလ့လာၾကရေအာင္ ။ ကၽြန္ေတာ္တို႔ အရင္ေန႔က ဖန္တီးထားတဲ့ Alignment ကိုသံုးျပီး လုပ္ၾကည့္ရေအာင္ ။ Command ယူဖို႔ကေတာ့ Home tab _ Create Ground Data panel _ Points menu _ Create Points - Intersections _ Direction/Alignment ျဖစ္ပါတယ္ ။ ကၽြန္ေတာ္တို႔ Command ယူျပီးတာနဲ႔ Alignment ကို ေရြးခ်ယ္ေပးဖို႔ေတာင္းပါတယ္ ။ ေရြးေပးျပီးသြားရင္ offset တန္ဖိုး သတ္မွတ္ေပးရပါမယ္ ။ မခြာဘူးဆိုရင္ 0 ေပါ့ ။ ခြာမယ္ဆိုရင္ ခြာမယ့္ဖက္ကိုလိုက္ျပီး +/- ထည့္ရိုက္ေပးရပါမယ္ ။ ေနာက္ထပ္ စမွတ္ သတ္မွတ္ေပးဖို႔ ေတာင္းပါမယ္ ။ ေနာက္ စမွတ္ကေနထြက္မယ့္ လားရာေတာင္းပါမယ္ ။ လားရာကို Bearing နဲ႔ျဖစ္ေစ Azimuth နဲ႔ျဖစ္ေစ ၊ ဒါမွမဟုတ္ ဒါရိုက္ကလစ္ခ်လို႔ ျဖစ္ေစ သတ္မွတ္ေပးနိုင္ပါတယ္ ။ ျပီးရင္ offset တန္ဖိုးထပ္ေတာင္းပါမယ္ ။ မခြာဘူးဆိုရင္ 0 ၊ ခြာမယ္ဆိုရင္ ခြာမယ့္ဖက္ကိုလိုက္ျပီး +/- ထည့္ရိုက္ေပးပါမယ္ ။ အဲဒီမွာ ပထမ offset က Alignment နဲ႔သက္ဆိုင္ျပီး ဒုတိယ offset က ကိုယ္သတ္မွတ္ေပးတဲ့ လားရာ ႏွင့္ သက္ဆိုင္တာျဖစ္ပါတယ္ ။ အဲဒီအဆင့္ျပီးသြားတာနဲ႔ ကိုယ္သတ္မွတ္ေပးတာ မွန္တယ္ဆိုရင္ ပြိဳင့္ေရာက္မယ့္ေနရာကို ၾကိဳျမင္ေနရပါျပီ ။ ေနာက္ ပိြဳင့္ကုဒ္ နဲ႔ အျမင့္တန္ဖိုးမ်ားကို အလိုရွိသလို ဆက္ထည့္ျပီး ပြိဳင့္ဆြဲလို႔ရပါျပီ ။ စဆြဲၾကည့္ရေအာင္ ။
Now we will study creating points at a Direction and Alignment Intersection. We will use the alignment was created in yesterday. We will take the command from Home tab_Create Ground Data panel _ Points menu _ Create Points - Intersections _ Direction/Alignment . After we activated the command, we need to choose alignment as desired. And we need to define the offset value. If we don't want to offset, value must be "0".If we want to offset, please type the value with +/- sign as we want. After that, we need to mark the start point and direction. We can define the direction by bearing or azimuth or direct click as we want. And then, we need to define offset value again. In here, the first offset value is related with alignment and the second offset value is related with the direction we defined. After we finished these steps, we can see the preview of point location if we do correctly. And then , we have to continue defining the point description and elevation as we desired. OK, Let's draw it.
