Blocks

PARAMETERBLOCKS
PurposeThis parameter controls whether blocks are created in the SVG file (as group codes) or whether a “flat” file is created with no block structure.
Example-BLOCKS=IGNORE
JSON{“CreateBlocks” : false}
ValuesIgnore/Off/No: Turns off block creation On/Yes/“Blank”: Turns on block creation (Default)
AliasNone
UseSVG Only

Break By Layer

PARAMETERBL
PurposeThis parameter forces the converter to output each AutoCAD Layer as a separate output file. The files are all defined in the same definition space and, if overlaid, will form a composite drawing equivalent to the drawing created if this parameter is not used.
Example-BL
JSON{“BreakByLayer” : true}
AliasNone
UseWith SVG Only

Building

PARAMETERBUILDING
PurposeThis parameter allows the specification of the name of the Building. This is an informational only field that is added to the Metadata area of the SVG file.
Example-BLDG=“New Office Building”
Alias-BLDG
UseSVG Only

Floor

PARAMETERFLOOR
PurposeThis parameter allows the specification of the name of the Floor in the Building. This is an informational only field that is added to the Metadata area of the SVG file.
Example-FLR=“4th Floor”
Alias-FLR
UseSVG Only

List Area

PARAMETERLIST AREA
PurposeThis parameter causes the area of closed polygons to be output.
Example-LISTAREA
JSON{“ListArea” : true}
Alias-LA
UseSVG Only

Postfix

PARAMETERPOSTFIX
PurposeThis parameter defines a string to be added to all SVG Ids.
Example-POSTFIX
JSON{“PostFix” : false}
UseSVG Only

Raster

PARAMETERRASTER
PurposeThis parameter causes a raster-based SVG/SVGZ file to be created instead of a vector-based file.
Example-RASTER
JSON{“RASTER” : true}
UseSVG/SVGZ Only

Thumbnail Line Weight Minimum

PARAMETERLWTMIN
PurposeThis parameter defines the minimum width to be used for entities in the Thumbnail file.
Example-lwtmin .5
UseSVG Only

Thumb Size

PARAMETERTHUMBSIZE
PurposeThis parameter defines the threshold to be included in Thumbnail file
Example-THUMBSIZE=2
UseWith SVG Only

Size

PARAMETERSIZE
PurposeThis parameter defines the size of the SVG file. This is useful for display exact graphical information. The default is 2500. A large size will typically give a larger file.
Example-SIZE=10000
UseWith SVG Only

Precision

PARAMETERPrecision
PurposeThis parameter sets extra coordinate precision in the SVG file. This will increase the precision within the defined size of the drawing. For very high precision use a combination of Size and Precision. Precision can be between 2 and 15. A high coordinate precision will typically give a larger file.
Example-PRECISION=12
Alias-PC
UseWith SVG Only
