Simply select the type of DXF entities that must be processed.

Exported coordinates are as follow :

• Circles, Arcs, Ellipses : center point.
• Blocks, Single Line Text, Multiline Text, Point : insertion point.
• Lines : end points.
• 2D Polylines, 3D Polylines, Splines : each vertex of the polyline, and optionally "additional points", meaning vertices that have been added by Curve-fitting or Spline-fitting.

. Exporting Unique Number

The Unique Number is an arbitrary number given to all processed entities by the program. You must give a start number and an optional prefix to add to this number. (For ex : "N=" or "Num:" etc.).

. Exporting X (East) coordinate and Y (North) coordinate

You can give an optional prefix to add to the X or Y coordinate. This can be any string (max 50 chars) like "X=" or "Y:" etc. You can also choose the number of decimals to use for the values of the coordinates.

. Exporting Z (Elevation) coordinate

You can give an optional prefix to add to the Z coordinate. This can be any string (max 50 chars) like "Zcoord:", etc. You can also choose the number of decimals to use for the Z value. If you select the "Force to this value" option, then each Z value will be replaced by the value in the edit field.

. Exporting custom data

The Code section allows to export various data in addition to the Number and X,Y,Z coordinates :

• Entity Type : this is the DXF entity type : POINT, LWPOLYLINE, INSERT, TEXT etc.
• Entity Layer : the layer on which resides the entity.
• Entity Handle : a unique hexadecimal number that identifies each entity in the DXF file.
• Block Name : name of the block (if applicable), otherwise an empty string.
• Text String : the text string for the Single Line Text and Multiline Text entities (if applicable), otherwise an empty string.
• Label : any text string that you choose. You must specify a string.
• Sequential Number : a unique number given to each processed coordinate point. For entities that have more than 1 coordinate point (polylines, lines ...), the number is different for each point. You must specify a start number.
• Group Number : a number given to each processed entity. For entities that have more than 1 coordinate point (polylines, lines ...), the number is the same for each point. You must specify a start number.

You can give an optional prefix to add to the custom data and specify a Separator for each of the custom data fields.

Examples of exported data

Example 1 : Unique Number starting at 1 with a "N=" prefix, East coordinate with a "X=" prefix and 2 decimals, North coordinate with a "Y=" prefix and 2 decimals, Elevation forced to 10.00 with a "Z=" prefix and 2 decimals, Entity type, Entity layer, a Group Number starting at 100 and a Sequential Number starting at 1001. Both separator are ",".

N=1,X=100.12,Y=125.36,Z=10.00,POLYLINE,LAYER1,100,1001
N=2,X=110.11,Y=225.32,Z=10.00,POLYLINE,LAYER1,100,1002
N=3,X=120.55,Y=555.32,Z=10.00,POLYLINE,LAYER1,100,1003
N=4,X=1120.55,Y=5515.32,Z=10.00,LINE,LAYER2,101,1004
N=5,X=1121.55,Y=5115.11,Z=10.00,LINE,LAYER2,101,1005
N=6,X=100.55,Y=500.32,Z=10.00,CIRCLE,LAYER3,102,1006

Example 2 : Unique Number, East coordinate, North coordinate, Elevation (all with 3 decimals), Entity type, Entity layer. Data fields separator is "," and Code fields separator is "_"

1,100.121,125.364,10.000,POLYLINE_LAYER1
2,110.112,225.321,14.000,POLYLINE_LAYER1
3,120.552,555.322,22.055,POLYLINE_LAYER1
4,1120.555,5515.131,13.221,LINE_LAYER2
5,1121.551,5115.111,13.159,LINE_LAYER2
6,100.550,500.320,11.001,CIRCLE_LAYER3

Example 3 : East coordinate, North coordinate, Elevation (all with 3 decimals), Unique Number, Entity type, Test string. Data fields separator is " " and Code fields separator is " ".

100.121 125.364 10.000 1 POLYLINE
110.112 225.321 14.000 2 POLYLINE
120.552,555.322,22.055 3 POLYLINE
1120.555,5515.131,13.221 4 TEXT This is a text
1121.551,5115.111,13.159 5 TEXT This is another text
100.550,500.320,11.001 6 MTEXT This is another text from a MTEXT entity
