3/19/2023 0 Comments Autodesk graphic arc text![]() Search Envelope parameters apply to both vector and raster datasets and can be particularly efficient if the source format has a spatial index. In FME, the easiest way to define a search envelope is to use search envelope parameters.ĭefining a search envelope is the most efficient method of selecting an area of interest because FME will read only the data that is necessary – it does not have to read an entire dataset. If the parameter Explode Blocks Into Entities is selected, and this parameter is also selected, then the insert points of exploded blocks are output as point features.Įxplode Selected Blocks: This parameter is a a space-delimited list of the block names that are to be exploded, and is processed only when Explode Blocks into Entities is selected.Ī search envelope (also known as a bounding box) is a rectangular area that defines a geographic area. The original insert is not part of the block definition, but this parameter allows the insert location to still be represented.Įach block member feature will include the attribute autocad_block_insert_. When the reader resolves blocks, it outputs a feature for each of the AutoCAD entities that are part of the block definition. ![]() When selected, the reader adds the insert point location as attributes to the block component entities when resolving (or exploding) inserts entities. This parameter also affects related symbology attributes such as autocad_lineweight and autocad_color which may have ByLayer values. If this parameter is unchecked, the block members will have the layer information of their respective layers.Įxamples of layer specific attributes are autocad_layer, autocad_layer_hidden, and autocad_layer_color. If this parameter is checked, all block members will have the same layer information as that of the original block. This parameter applies only if Explode Blocks into Entities is selected. Specifies how the reader sets the layer information attributes of the block component entities when resolving (or exploding) insert entities. Use Block Layer Information for Components To change the layer information on the component features to match their layer-based feature type, use the Use Block Layer Information for Components parameter. 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. If this parameter is unchecked, the block members will appear on their respective layer-based feature types. If this parameter is checked, all block members will be on the same layer-based feature type as that of the original block. This parameter applies only if Explode Blocks into Entities is checked. Specifies how the reader sets the feature type of block component entities when resolving (or exploding) insert entities. Usual AutoCAD-to-AutoCAD translation setting: Not selected Byĭefault, all block members will be on the same layer as that of the original Updated for each block at the outermost level. Nesting is permitted, however, the autocad_block_number attribute is only Which is set to the same value for each block so that the features comprisingĮach block may be combined in subsequent processing. This results in the full graphical representation of theīlock transferred through FME, but the exact insertion point of the blockĮach block member feature is given the attribute autocad_block_number When the reader resolves blocks, it outputs a feature for each of theĪutoCAD entities that are part of the block definition. When selected, this parameter explodes blocks and return the entities that form theĬomponents of the block as separate features. For Extended Entity Data attributes to appear, the reader parameter Read Interpreted Extended Entity Data must be selected. The layers will be used to create FME feature types as in the Group by Layer Name selection however, the attributes of all the entities belonging to a layer will be accumulated and also added to the FME feature type for that layer. The schema will be generated using both the layers and entities in the source dataset. This list is set by the reader capability and is not limited to geometries which occur in the given source dataset. The schema will be generated using all the possible AutoCAD geometry types as FME feature types. The schema will be generated using layers in the source dataset as FME feature types. Group entities by layer name or geometry, or build AutoCAD schema by scanning extended entity data. Specifies the overall structure of the schema and data for DWG file reading.
