Autocad Civil 3D - Membuat Cross Section

Sebelum nya saya pernah mendapat tugas membuat back up data Cut and Fill yang di mana mengharuskan saya menghitung luas penampang jalan satu per satu untuk mendapatkan koordinat beserta luasan nya untuk di masukan ke dalam format back up data di excel.

Kemudian yang saya perlukan adalah sebuah polyline tertutup yang menjadi area cut and fill dalam setiap potongan jalan.Sebenar nya kita bisa buat satu per satu polyline mengikuti area cut and fill,Tapi bagaimana jika kita harus membuat ribuan polyline ? Tentu nya akan membuthkan banyak waktu dan melelahkan.

Disini saya akan beri Autolisp untuk membuat Boundary dari semua hatch yang ada di gambar yang berupa Polyline tertutup.

Pertama tama silahkan anda copy paste script autolisp di bawah ini ke dalam notepad kemudian kalian save dengan nama " Boundary.lsp "

;;; Bulk-recreate-hatch-boundaries.lsp ;;; v.2.0 by toni @ http://gistncase.blogspot.com ;;; ;;; This Autolisp routine is intended solely for Dwg to Gis conversion purposes. ;;; ;;; It will recreate boundaries around all the hatch patterns in a drawing at once. ;;; The recreated boundaries will be drawed in custom new layers and will consist ;;; only of closed simple polylines (thus interpreted as polygons by Gis drivers). ;;; Tested on Autocad 2012. ;;; ;;; Features: ;;; - creates closed-polyline boundaries (Gis polygons) ;;; - assigns the same hatch color to the boundary ;;; - draws in new (property cloned) layers with custom names ;;; - can delete all the previous boundaries ;;; - handles every kind of known boundary path data ;;; ;;; credits: ;;; Lee Mac @ http://www.cadtutor.net/forum/showthread.php?49122-Converting-SPlines-to-lines&p=334674#post334674 ;;; Murray Clack @ http://forums.autodesk.com/t5/Visual-LISP-AutoLISP-and-General/Recreate-multiple-hatch-boundaries-as-polygons-each-in-the-layer/td-p/3275725/page/2 ;;; Autodesk, Inc. @ http://www.cadtutor.net/forum/showthread.php?46610-Use-Entmake-to-create-layer-with-colour-set-to-Truecolour ;;; Jimmy Bergmark @ http://www.jtbworld.com/lisp/hatchb.htm ;;; VVA @ http://www.cadtutor.net/forum/showthread.php?12493-lisp-for-converting-ellipse-to-polylines (prompt "\nEnter BULKRHB to execute") (defun c:BULKRHB ( / dorctl osmode pltype cmecho j SPLINECONVERSIONVALUE BUTTDISTANCETOLERANCE) (vl-load-com) (defun ent2pline ( ent step / etyp pts cdst leng ret ) ; ent2pline: converts *any* entity to a segmented lwpolyline (no input check) ; returns the new object entity name and deletes the former. ; the lamba function is inspired by a public domain snippet by Lee Mac ; (should be optimized "pinning" the known vertexes or much better ; performing a _pedit-like "smart" conversion...) ; ; ent2pline entityname intvalue ; entityname : dxf entity name (might be *any*) ; intvalue : segment max length in case of ellipse, circle (setq etyp (vlax-get-property (vlax-ename->vla-object ent) 'ObjectName)) (cond ((or (= etyp "AcDbPolyline")) (setq ret ent) ) ((= etyp "AcDb2dPolyline") (progn (command "_.CONVERTPOLY" "_L" (ssadd ent) "") (setq ret ent) ;convertpoly won't create a new entity ) ) ((or (= etyp "AcDbLine") (= etyp "AcDbArc")) (progn (command "_.PEDIT" (ssadd ent) "_Y" "") (setq ret (entlast)) ) ) ((= etyp "AcDbSpline") (progn (command "_.PEDIT" (ssadd ent) "_Y" SPLINECONVERSIONVALUE "") (setq ret (entlast)) ) ) ((or (= etyp "AcDbCircle") (= etyp "AcDbEllipse")) (progn (setq cdst 0) (setq leng (vlax-curve-getDistatParam ent (vlax-curve-getEndParam ent))) (if (<= leng step) (setq step (/ leng 12)) ); when step is less than obj length "simplify to twelve segs" (while (< cdst leng) (setq pts (cons (vlax-curve-getPointatDist ent cdst) pts) cdst (+ step cdst) ) ) (setq pts (cons (vlax-curve-getPointatDist ent leng) pts)) (entmake (append (list (cons 0 "LWPOLYLINE") (cons 100 "AcDbEntity") (cons 100 "AcDbPolyline") (cons 90 (length pts)) (cons 70 0) (assoc 8 (entget ent))) (mapcar (function (lambda ( a ) (cons 10 a))) pts))) (entdel ent) (setq ret (entlast)) ) ) ( T ;skipping anything else, eg.: "AcDbText", "AcDbMText" (in progress...)

Jika sudah di save sekarang kita kembali ke autocad untuk memasukan autolisp tadi yang sudah di save.Berikut cara nya :

• Di menu Command silahkan ketik APPLOAD
• Kemudian pilih file Boundary.lisp yang sudah di save tadi.
• Lalu Klik Load
• kemudian pilih salah satu
• Always Load = Untuk selalu me Load Autolisp itu ketika membuka gambar.
• Load Once = Untuk meload sementara saja (anda harus me load ulang ketika gambar di close)
• jika sukses akan mucul tulisan Boundary.lisp seccesfully loded
• kemudian klik close

Selanjut nya adalah kita akan memberi semua hatch yang ada di dalam gambar secara otomatis.

• Di menu Command ketikan perintah BULKRHB
• Enter
• 
  
• Lalu ketik Add
• Enter 3x
• Selesai silahkan cek semua hatch sekarang sudah mempunyai boundary semua

Untuk merubah warna nya silahkan klik salah satu boundary kemudian,klik kanan lalu select semiliar kemudian ganti warna nya melalui kolom properties.
Contoh gambar saya yang sudah jadi boundary nya saya menggunakan warna kuning untuk boundary nya.
