AUTO CADD

Macam mana nak plot drawing.

1. File-plot-pilih printer-paper size-centre the plot-fit to paper-pada what to plot, pilh windiw dan select mana nak print.

Scale dan cari area gunak auto cadd

1. Scale kan dulu drawing tersebut
-sc-pick point-r-masukkan jarak asal-masukkan scale sebenar-pl-sambungkan semua-Li
2. One more method to change a scale...example: 1:400 to 1:1 :-
-sc-specify base point (click kat mana2)-masukkan scale 400/1000 = 2/5 enter...so dah jadi scale 1:1 ...ukur jarak guna dmension mesti dapat jarak sebenarnya. then start kira area guna kaedah no.1.

Cross Section

1. Nak start buat cross section, kena ada maklumat proposed road level, ogl data and distance. Biasanya guna software msroad.

2.Ada satu kes di mana cross section perlu disiapkan untuk retender but when checked as built survey done by contractor scale tak betul but data existing ground level valid.(datum tak boleh pakai sebab nak guna datum pada construction dwg) So what to do...nak pulangkan balik ....lambat lagi leeeee...so kena buat sendiri.........Bawah ni step dia...
- dapatkan soft copy cross section connstruction dwg....tukar scale kepada 1:1...
- delete data ogl dalam cross sect. construction dwg ....then masukkan data as built or EGL...before masukkan data EGL, dapat jarak sebenar ketinggian atau level sebenar keadaan di tapak iaitu aras datum pada construction drawing tolak dengan EGL/as-built. pada setiap distance. Dah dapat level sebenar masukkan nilai ketinggian tersebut kedalam cross sect. yang hendak di buat. Caranya ialah -line-pick point dekat jarak dia-masukkan nilai ketinggian dia iaitu datum tolak EGL-enter 2kali....then sambungkan dia..

Nak Cari Area at Cross Section and Keluarkan Coordinat X,Y

1. Check scale, make sure scale 1:1
2. Draw line. Starting point is from as built level at centre of the cross section and tarik ke bawah ....dan masukkan level as built level/Existing ground level. Then enter 2x.
3. Set UCS - type UCS-and pick kat hujung line yang baru buat tadi. Then enter.
4. Set Boundry - BO - pick kat centre of the area
5. List (Li) - enter
6. Copy list to excel and nak sort ikut column, go to data-text to column.....
