Converting 2D Textto 3D PointsThere are severa w ays to inputdata;here in M alaysia,the m ostcom m on data used aresurvey points(also know n as spotheights)and contourlines.H ow ever,beforecreating a ground surface,youshould try to clean the data up as m uch as possible so thatyou havelessediting w ork later

Itis com m on to receive a 2D drawing w hich only contain the textrepresenting the elevation ofeach spotheight;i.e.there are no pointsw ith elevations.In thiscase,w e m ustcreate 3D pointsateachposition Autodesk Civil3D isable to autom atically create 3D pointsforyou based on each textvalue thatrepresents the elevations forthepoints

The conversion process isverysim ple:first,you need to generate an

XYZ file from yourdraw ing,afterw hich you w illim portthe file intoAutodesk Civil3D

Verify The Drawing Data

O pen the drawing containing the spotheights in AutodeskCivil3D .Ifyou had received the draw ing from an externalsource,copy itto yourproject’s dw g folderfirstbeforeopening it.

1.

Check the drawing to see w hereand how the pointsand/ortextinform ation is stored.They are typically saved in separatelayers.

2.

Ifyourdraw ing already contains3D points,you don’thave toconvertthe textinto 3D points;you can straightaw ay use these

points to create yourexisting ground surface.H ow ever,besure to check thatthese 3D pointsare placed atthe correctelevations.

Note: To check if the points are in 3D or not, use theProperties Window and check the Z value of each pointaga inst the relevant text.

Ifyourdraw ing only contains the textvalues,notedow n thelayersw hich contain those text.

Creat ing The 3D Points

You cannotcreate the 3D pointsdirectly from thisdraw ing,socreate a new draw ing oropen a blank drawing (forexam ple,the survey.dwg created from the previouschapter).

1.

IfyourToolspace isnotalready open,open itfrom the m enuGeneral > Show Toolspace…

2.

In Civil3D interface,click on Map > Query > Define

Query…

3.

In the Define Query w indow ,click on Drawings and click Attach .

4.

You can brow se directly to the folder containing yourdraw ing,oryou can use aliases.

5.

Note: Using Aliases Aliases in Autodesk Map is a shortcut to your folder. This isextremely useful when you need to access a folder in Autodesk Map often.

To create an alias:

Click the Cr e a t e / E d i t A l i a s e s icon.1.

Before you startconverting yourdata,firstyou need to filteroutallinform ation to ensure thatonly the textvaluescontaining the relevantelevation data w illbe converted.Youwouldn’tw anttextcontaining w ordslike “Tree” or“School”inyourpointdatabase!To filteroutthe data,you w ould be usingQ ueries.

In Civil3D interface,click on Map > Query > Define

Query…8.

In the query w indow ,filter outthe data by using theoptionsunder Query Type .

9.

Typically,Property isused as the textvalues are often placedon a separatelayer.Click Property .

You w illsee a preview ofallthe data in yourdraw ing.You canstillzoom and pan the draw ing to view the data,butifyou

14.





redraw ,the data w illdisappear.Take a look atyourdraw ing tom ake sure thatthedata has been properly filtered.O nce you have verified thatthe data has been filtered properly,you can run the conversion now .Go back to the Q ueryw indow.

15.

W ithoutm odifying the query settings,under Query Mode ,selectthe Report radio button,and click Options .

16.

This isw here you specify yourreporttem plate,i.e.yourXYZfile.Click Expression .

17.

In the Report Template Expression w indow ,open theProperties tree.Scrolldow nw ardsuntilyou see X1.H ighlightitand click OK .

18.

Click Add. You should see .X 1 added in the top panel.19.





Repeatthe above steps to add Y1.20.Forthe lastcolum n,don’tselect Z1!This isbecause the Z-value in thedraw ing is0.Instead,you w ould be m aking use ofthe textvalue as theelevation.Repeatthe above steps to addSTRING .

21.

Click the Browse button,and type in the nam e ofthe XYZ fileyou aregoing to generate.

22.

Click OK ,and then click Execute Query .The XYZ file w illbegenerated.23.

You can check yourfileby opening itfrom W indowsExplorer.24.





To im portthe points,go to the m enu Points > Create

Points > Import Points .25.

U nderForm at,select ENZ (comma del imited) from thedrop-dow n list.Note:

26.

The drop-down list contains a list of standar d file formats in Autodesk Land Desktop. You can easily create your ownformat if you need to.

P = Point NumberN = NorthingE = EastingZ = ElevationD = Description

Comma delimited means the columns ar e separa ted by commas, whereas space delimited means the columns areseparated by spaces.

U nder Sour ce File ,click the open icon,brow se to the foldercontaining yourXYZ file,and select the file.

27.

Check the Add Points to Point Group ,and click the blueicon on the right.Create a pointgroup nam ed Existing.This isto m ake iteasier foryou to create yourexisting ground surfacelater.By nam ing yourpointgroup Existing,you w illknow thatallthe points in thisgroup are m eantforyourexisting groundsurface.

Thank God for technology.. ;-).

Its a LO T sim plerand quickerand m oreaccurate to useTopoGX.

Allyou need do ispress the 2D to 3D converttoolbar button,then press the big "ConvertN ow "button.The conversion is

done in a few secondsand autom atically convertsyourTextlevels to Z levelsand insertsthem at the visually associatedinsertion cross,w hether itbe a Pointentity orblock insert.

Its also gotgreatfeatures like a really easy 3D View er,instantSurface Contours,Surface H eightcolouring,Flow Arrow s,Longsectioning and Ithink they m entioned thatthey w illbeadded Volum ing soon!

A reply to "bonetiberiu@ gm ail.com ":

Anotherreason w hy the "parsing erroroccurs"isbecause ofthe TextEncoding form at.Try so "save as..."the textfile usingAN SI encoding instead ofU N ICO D E.You can search theoptionson the "save as..."w indow .Sim ple as that.Everythingwillw ork justfine.
