Tsim kom muaj contour kab siv AutoCAD

Ua ntej peb saib xyuas cov ntaub ntawv xa mus rau Excel siv Softdesk, tam sim no cia saib yuav ua li cas los tsim theem curves, tus txheej txheem nyob rau hauv Civil3D tau simplified, tiam sis feem ntau muaj tib lub logic uas kuv yuav piav qhia ntawm kuv cov qub CAD Topography phau ntawv.

1. Teeb ntawm cov ntsiab lus nce

Qhov kev ntsuam xyuas uas kuv tau ua nyob rau hauv av muaj lub hauv paus axis uas kuv tau coj los ua kab hauv paus txhua 50 meters, ntawm cov ntsiab lus no kuv tau nce qhov siab thiab tom qab ntawd kuv tau coj cov kev xav mus rau sab xis thiab sab laug nyob ntawm qhov tsis sib xws ntawm thaj av. Kuv kuj tau coj qhov kev nce siab ntawm cov vertices ntawm txoj kev hla. Kev kos duab ntawm qhov no yog ua tiav hauv ib txwm AutoCAD, kos duab kab yooj yim, siv cov voj voog thiab cov ntsiab lus ntawm kev sib tshuam. Txij li thaum Softdesk 8 tsuas yog ua haujlwm nrog AutoCAD 14 kuv yuav tsum khaws cov ntaub ntawv raws li version 14 kom tuaj yeem txhawb nqa hauv Softdesk.

2. Taw Chaw

• Load Softdesk (AEC / softdesk programs), yog tias koj tsis tau ua ib qhov project xaiv los tsim ib lub tshiab
• Xaiv lub cogo, ces xav tau
• Teem caij rau cov ntsiab lus (Cov ntsiab lus / teeb / teem caij cov ntsiab lus)

• Ntawm no koj yuav tsum teeb tsa qhov chaw pib, thiab "kev nce siab ntawm" kev xaiv, yog li koj tuaj yeem ntaus lawv ncaj qha rau ntawm kab hais kom ua, yog tias koj xav ntxiv cov lus piav qhia koj tuaj yeem tawm "tsis siv neeg piav qhia" unchecked, ces peb ua tau. Ceev faj, xyuas kom tseeb tias koj tawm hauv qhov "automatic elevations" kev xaiv tsis ua haujlwm kom cov no nkag mus rau ntawm kab hais kom ua.

3. Inserting ntsiab lus

• Rau qhov no peb xaiv cov ntsiab lus / teeb cov ntsiab lus / kev xaiv phau ntawv ces ntxig txhua qhov taw qhia, ceeb toom qhov nce ntawm kab hais kom ua. Yog hais tias koj muaj cov ntsiab lus nyob rau hauv 3 qhov ntev los yog coj los ntawm tag nrho cov chaw nres tsheb, koj tuaj yeem tawm ntawm qhov "automatic elevations" kev xaiv tsis ua haujlwm thiab tsuas yog nyem rau ntawm lawv nrog lub active snap.
• Cov ntsiab lus ntawm sab xis yog 23 vertices ntawm kuv txoj kev hla, thiab lawv yuav nqa cov lus piav qhia tsis siv neeg "pol"

• Tam sim no kuv nkag mus rau cov ntsiab lus sab hauv, uas muaj qhov sib txawv nomenclature, rau qhov no kuv deactivate "automatic description" thiab sau ib qho lus piav qhia txhua zaus peb tso cov ntsiab lus.

4. Qhia Txog Tsim

• Ua qhov no xaiv AEC / softdesk cov kev pab cuam / DTM / ok

• Tam sim no tsim ib nto mus cob rau cov ntsiab lus no, xaiv nto / tshiab / ntxiv npe / ntxiv piav qhia / ok
• Ntxiv cov ntsiab lus nkag mus rau qhov chaw tsim, peb yuav pib los ntawm kev tsim tus contour, yog li xaiv qhov saum npoo / nto cov ntaub ntawv / tus qauv faults / los ntawm tus xov tooj
• Sau rau hauv kab lus hais cov ntsiab lus muaj nyob rau hauv lub traverse nyob rau hauv no txoj kev 1-23, ces mus kaw peb rov ua 1
• ces peb nkag mus, muab lub npe mus rau lub voj voog thiab rov nkag ntxiv

5. Triangulation (Digital Terrain Model lossis MDT)

• Ua li no xaiv qhov saum npoo / tsim nto / xaiv ob qho kev ua yuam kev, kev sib txuas lus thiab cov ntsiab lus xaiv tsis pom kev tsis tag siab
• ces peb tsis tau, sau, Yog saib rau daim duab peb sab thiab ces sau
• Peb daim duab yuav tsum zoo li no:

6. Tsim Qib Curves

• Tua txhua cov khaubncaws sab nraud povtseg kws koj tsi xaav saib thaum lub sijhawm ntawd
• Txhim kho cov duab cim los ntawm kev xaiv cov contour / contour zog thiab pab rau cov nram qab no:

• Tam sim no peb tsim cov curves nrog cov kev xaiv contour / tsim contour

• Peb xaiv lub caij nyoog tseem ceeb thiab theem nrab curves, peb yuav siv qhov sawv daws yuav loj tshaj txhua 5 meters thiab cov theem nrab txhua 1, thiab peb xaiv lub npe ntawm cov khaubncaws sab nraud povtseg
• Tom qab ntawd peb ua tau zoo, thiab nkag mus
• Thaum koj hloov cov xim rau cov khaubncaws sab nraud povtseg, koj yuav tsum ua haujlwm kom zoo li no.

Hauv lwm cov kev sib txuas peb pom tias yuav ua li cas thiaj ua tau nrog rau 3D, Google ntiaj teb, Bentley Qhov Chaw, manifold GIS, ArcGIS.
