Contours kubva polylines (Step 2)

Mutsamba yapfuura ichave ne georeferenced chifananidzo chine mitsara yemitsara, zvino tinoda kuvashandura contours ye Civil 3D.

Digitize curves

Nokuda kweizvi kune mapurogiramu anenge achitsvaga maitiro, akadai AutoDesk Raster Design, zvakaenzana ne Descartes in Bentley or ArcScan kuESRI. Mune ino kesi ini ndiri kuzozviita netsoka, kudhirowa polylines.

Havafanirwi kuitwa smartlines, asi neyero polylines.

Zvinokurudzirwa kuti ugadzire mazinga ane mazita emakona makuru. Rubatsiro rwezvinoonekwa.

Zvinoshandiswa kushanda nemitsetse yeupfumi hwe0.30 kuti uone kufanirwa mberi.

Kuti uone kubatana kwemasara, bhodhi yeWT inofanira kushandiswa.

Smooth uye ubatane nemakumbo.

Izvi hazvigare zvichidikanwa, asi nekuda kwekudzidzisa, ngatione kuti zvinoitwa sei. Izvo zvinoitika kuti mamwe polylines akatadza kubatanidzwa nekuti iwo murairo wakakanganiswa, kana isu takaita mamwe maveices zvishoma emujaho usingaite neakakombama.

• Iko shanduro yepa polyline inoshandiswa pedit
• Nzira yakawanda inosarudzwa yakasarudzwa, ine tsamba M uye ipapo pinda
• Zvose zvinyorwa zvepa polylines isu tinotarisira kurapa zvinosarudzwa
• Tinoshandisa J kuti tibatane
• Tinoshandisa S kuti tinyorove

Ita wekumusoro kune polylines
Iwe unofanirwa kubata macurves, rimwe nerimwe, kumisikidza zvivakwa uye nekugadza inoenderana kukwirisa. Mune ino kesi, sezvo iwo ari ega 25 masentimita, iyo green curve ingangove makumi matatu nemaviri, uye zvinotevera zve kusvika pabhuruu raizova 322.25, 322.50, 322.75

Kana iri yekudenga, ona kuti nzira dzinoshandiswa kuziva kuti hunhu hwenzvimbo iyoyo hwakamira sei. Neichi chikonzero, iwo makuru anofanirwa kuiswa mune rakasiyana ruvara.

Inogona kuvimbiswa kuti dzose dzakange dzichikwidziridzwa, zvichiona maonero ekusimudzira.

Wona> 3D Maonero> NE Isometric.

Shandura polylines kumiganhu yepakati.

Kuti tiite izvi, tinoenda kuruboshwe rweseri, pane tab Prospector, uye isu takagadzira nzvimbo itsva, yemhando TIN.

Pano, kana pane zvisikwa zvisikwa, unogona kuona zvinhu, pakati pazvo zvinoonekwa Masks, Watershedsuye Deffinitions. Apa ndipo panotariswa nzira yekutenderera mitsaraContours).

Kanda-kona pane Contoursipapo wedzera.

Mutsanangudzo tichaisa Curves scan, uye tinozoita ok. Ipapo isu tinosarudza ese ma polylines atakatora manhamba.

Ona kuti kubva ipapo, triangulation inogadzirwa.

Ruramisa zvinhu zvemashure.

Imwe tsananguro inosara inokonzeresa kusagadzikana kana zvikaitwa kekutanga. Uye zviripo, kuti mitsara yemakona inoita kunge isingaonekwe, asi inyaya ye kuratidza nzvimbo.

Kuti uite izvi, penya-kona uye sarudza Hora uso style. Mune ino pani, isu tinosarudza iyo tab Contours. In Kushushikana Nenguva, tinosarudza nzvimbo imwechete iyo mepu yakatarwa, kuti tione kana zvinhu zvose zvakanaka.

Mhemberero huru yega yega 1.00 uye yechipiri mavharo eE0.25 imwe neimwe.

Uye ndizvozvo. Zviri pachena kuti kunyanyisa kune kurapwa kwekuita, nekuti chirongwa ichi chinoedza kuvhara iyo muganhu uchifunga kuti hapana kuenderera neimwe pepa. Tichaona kana mune imwe posvo tinozvifananidza neGoogle Earth data uye kusimudzira nzvimbo yekushanya kweshamwari Pipiles.
