This option specifies the types of AutoCAD drawing entities which will be included in schema generation and data retrieval.
If you select this option, the reader will use FME Feature Types to represent types of Civil 3D specific entities such as pipes.
If you select this option, in addition to FME Feature Types to representing types of Civil 3D specific entities, the AutoCAD Civil 3D Reader will use additional FME Feature Types to represent layers. All of the CAD entities in the AutoCAD drawing will be read according to the layer on which they are located. Although Civil 3D specific entities also belong to layers, they will only be read according to their object types.
Check this box if you want to explode blocks and return the entities that form the components of the block as separate features. This is generally left unchecked when performing AutoCAD-to-AutoCAD translations.
When the reader resolves blocks, it outputs a feature for each of the AutoCAD entities that are part of the block definition. The original insert is not output. This results in the full graphical representation of the block transferred through FME, but the exact insertion point of the block is lost.
Each block member feature is given the attribute autocad_block_number which is set to the same value for each block so that the features comprising each block may be combined in subsequent processing. Arbitrary deep block nesting is permitted, however, the autocad_block_number attribute is only updated for each block at the outermost level. By default all block members will be on the same layer as that of the original block.
Specifies how the reader sets the feature type of block component entities when resolving (or exploding) insert entities. This parameter applies only if Explode Blocks into Entities is checked. When performing AutoCAD-to-AutoCAD translations, it is generally unchecked.
When the reader resolves blocks, it outputs a feature for each of the AutoCAD entities that are part of the block definition. When checked, this parameter indicates that all block members will be on the same layer-based feature type as that of the original block. If unchecked, the block members will appear on their respective layer-based feature types.
This parameter is useful when resolving components and using a layer-based schema, and you want block component features to share a layer-based feature type. To change the layer information on the component features to match their layer-based feature type, use the Use Block Layer Information for Components directive.
Specifies how the reader sets the layer information attributes of the block component entities when resolving (or exploding) insert entities. This directive applies only if Explode Blocks into Entities is checked. When performing AutoCAD-to-AutoCAD translations, it is generally unchecked.
When the reader resolves blocks, it outputs a feature for each of the AutoCAD entities that are part of the block definition. When checked, this directive indicates that all block members will have the same layer information as that of the original block. If unchecked, the block members will have the layer information of their respective layers.
Examples of layer specific attributes are autocad_layer, autocad_layer_hidden, and autocad_layer_color. This parameter also affects related symbology attributes such as autocad_lineweight and autocad_color which may have 'ByLayer' values.
If you check Store Insert Location on Components, the reader adds the insert point locations as attributes to the block component entities when resolving (or exploding) inserts entities. This option is generally not checked for AutoCAD-to-AutoCAD translations.
When the reader resolves blocks, it outputs a feature for each of the AutoCAD entities that are part of the block definition. The original insert is not output, but this directive allows the insert location to still be represented.
This results in each block member feature having the following attributes: autocad_block_insert_[xyz].
Determines whether to resolve the entity's color, or keep it as "ByLayer". When checked (which is the default), the autocad_color attribute will contain the actual color by value (an integer between 0 and 255 inclusive) therefore preserving the original attributes.
For example, if you have an entity on a "rivers" layer, with its color set to "ByLayer", and the layer color set to "blue":
Note: This option is generally unchecked when performing AutoCAD-to-AutoCAD translations.
Specifies whether the reader should return visible attributes as separate text features or whether they should be returned as attributes of an insert feature. When this option is checked, then each visible attribute is returned as a single text feature.
Note: This option is generally checked when performing AutoCAD-to-AutoCAD translations.
Specifies whether the reader will explode the mtext entities into separate text entities. When exploding, the resulting text features represent fragments of text with the same mtext properties such as style and location. When not exploding, the mtext entity will be read as a single text feature.
Note: This is generally unchecked when performing AutoCAD-to-AutoCAD translations.
Determines whether polylines should have their elevation attribute treated as a Z coordinate (applies to light-weight polylines and 2D polylines).
Note: This option should not be set when performing AutoCAD-to-AutoCAD translations as the elevations converted to Z coordinates when read in will not be converted back to elevation attributes when written out.
Specifies whether or not to read hatches in a way that preserves their complex properties. If Preserve Complex Hatches is not checked, then the loops of each hatch entity will be converted to areas and aggregated together, and polyline bulges will be stroked. If Preserve Complex Hatches is checked, then the loops will be aggregated together as polygons, ordered such that any enclosing loop will be aggregates before any enclosed loop. Attributes will be added to store polyline bulge information.
Note: This option is generally checked when performing AutoCAD-to-AutoCAD translations.
Determines whether or not AutoCAD groups will be read. By default, FME will not read groups.
Determines how multi-line entities are read. If unchecked, multi-line geometry is constructed of lines containing only the explicit vertexes of the base line and the relative vertexes of additional lines. When checked, additional evaluation of multi-line properties is performed, which may result in additional vertexes and gaps in the geometry. The evaluated geometry form is a more complete geometric representation of a multi-line entity, but cannot be written without loss by the AutoCAD Writer.
Determines whether FME will attempt to read a graphical representation of Proxy entities which are placeholders for certain unsupported objects. By default, FME will not read Proxy Graphics.
Instructs FME to also read the entities from paper space. By default, FME only reads the entities from model space.
Instructs FME to ignore the user-defined coordinate system of the file being read. By default, FME applies the UCS when reading the coordinate data.
Note: This option is generally checked only when performing AutoCAD-to-AutoCAD translations.
Use this parameter when you have an Esri World file (*.wld) that you want FME to use when determining the coordinates for features in your dataset. When this box is checked, FME will search the directory of the dataset for a file with the same name as your dataset but with a .wld extension. If it cannot find a file with that name, it will then look for the file “esri_cad.wld” within the dataset directory. If either of those files exists, then FME will use the information in the files to translate the coordinates of the features in the dataset to their new geospatial coordinates. If the files cannot be found, then the translation will continue, using the coordinate information found in the dataset, without performing any additional transformation.
This parameter exposes Format Attributes in Workbench when you create a workspace:
Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that interact with the bounding box are returned.
If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.
Select this option to remove any portions of exported features outside the area of interest.
