OGR supports reading most versions of Auto. CAD DXF and writing Auto. CAD 2. 00. 0. version files. DXF is an ASCII format used for interchanging Auto. CAD drawings. between different software packages. The entire contents of the file is. DXF files are considered to have no georeferencing information through OGR. Architects, engineers, and construction professionals rely on the innovative design tools in AutoCAD software to create precise 2D and 3D drawings. In Excel we can access the data in a worksheet by using Sheet1. Trance Kick Sample. CellsRow, Column. We can loop through Sheet1. Cells and take action in AutoCAD based on the content. AutoCAD DXF OGR supports reading most versions of AutoCAD DXF and writing AutoCAD 2000 version files. DXF is an ASCII format used for interchanging AutoCAD drawings.

AutoCAD 2007 Tutorial First Level 2D Fundamentals Text by Randy H. Shih Oregon Institute of Technology MultiMedia CD by Jack Zecher Indiana University Purdue. Learn AutoCAD with tutorials that cover beginner to advanced techniques. Experts from lynda. AutoCAD training to help you master the software. Every point in an AutoCAD drawing file can be identified by its X,Y,Z coordinates. In most 2D drawings, the Zcoordinate value is 0. This system of coordinates is. Sub. Classes Where available, a list of classes to which an entity belongs. Extended. Entity Where available, extended entity attributes all appended to form a single text attribute. Linetype Where available, the line type used for this entity. Entity. Handle The hexadecimal entity handle. A sort of feature id. Text The text of labels. Supported Entities. The following entity types are supported POINT Produces a simple POINT geometry feature. MTEXT, TEXT Produces a POINT feature with LABEL style information. LINE, POLYLINE, LWPOLYLINE Translated as a LINESTRING. Rounded. polylines those with their vertices budge attributes set will be tessellated. Single vertex polylines are translated to POINT. CIRCLE, ELLIPSE, ARC Translated as a LINESTRING, tessellating the. INSERT By default, the block definition referenced by the INSERT will. MULTILINESTRING for a block. GEOMETRYCOLLECTION for block that contains points. If the block contains TEXT or MTEXT entities, they are not merged. Two configuration options are available to control the behavior of INSERT. DXFMERGEBLOCKGEOMETRIES To avoid merging blocks into a compound. DXFMERGEBLOCKGEOMETRIES config option may be set to FALSE. Use this option if you need to preserve the styling such as colors of. DXFINLINEBLOCKS See below. ATTDEF, ATTRIB Attributes ATTRIB are treated as TEXT entities, and. ATTDEF inside blocks are ignored. The behavior is. different when DXFINLINEBLOCKS is false see below. HATCH Line and arc boundaries are collected as a polygon geometry, but. HATCH entities. The DXFHATCHTOLERANCE config option determines the tolerance used when looking. DFACE, SOLID Translated as POLYGON, except for SOLIDS with only one. POINT or two distinct vertices LINESTRING. DIMENSION The DXF format allows each DIMENSION entity to reference. D that contains the. DIMENSION. If present, this anonymous block will be inlined. Otherwise, fallback will occur to a simple DIMENSION. MULTILINESTRING feature. Arrowheads, if present, are translated as one or more additional features. The fallback renderer will render nonlinear dimensions as if they were linear. LEADER, MULTILEADER The leader line is translated as a LINESTRING. An arrowhead, if present, is translated as one or more additional features. Text for MULTILEADER entities is translated into a POINT feature with a label. Note Spline paths are not supported for either type of leader, and only. MULTILEADERs block content is unsupported. A reasonable attempt is made to preserve line color, line width, text size. OGR feature styling information when translating entities. Currently no effort is made to preserve fill styles or complex line style. The approximation of arcs, ellipses, circles and rounded polylines as. This angle is the OGRARCSTEPSIZE. This defaults to. OGRARCSTEPSIZE. DXFINLINEBLOCKS. The default behavior is for INSERT entities to be expanded with the. BLOCK they reference. However, if the DXFINLINEBLOCKS. FALSE, then the behavior is different. A new layer will be available called blocks. It will contain one or. BLOCK defined in the file. In addition to the usual. Block attribute indicating what block. Note, in GDAL 2. 2. ATTDEF entities in the blocks layer will have an Attribute. Tag attribute. giving the tag of the ATTDEF entity. The entities layer will have several new attributes. Block. Name The name of the referenced block. Block. Scale The X, Y, and Z scale factors. Block. Angle The angle of the block in degrees. Block. OCSNormal The unit normal vector of the object coordinate system. OCS of the INSERT entity. Block. OCSCoords The OCS coordinates of the insertion point. Block. Attributes The text content of attributes associated with this. Each entry in this string list contains an attribute tag, followed by. INSERT entities will populate these new fields with the corresponding. INSERT entities will not have block geometry inlined instead they will. POINT geometry for the insertion point. The intention is that with DXFINLINEBLOCKS disabled, the block references. On export this configuration will result in the. Character Encodings. Normally DXF files are in the ANSI1. Win. 12. 52 encoding. GDALOGR attempts. UTF 8 when reading and back into ANSI1. DXF files can also have a header field DWGCODEPAGE indicating the. In GDAL 1. 8. x and earlier this was ignored but from. GDAL 1. 9. 0 and later an attempt is made to use this to recode other. UTF 8. Whether this works will depend on the code page naming. GDALOGR is built against the iconv library for character recoding. In some cases the DWGCODEPAGE setting in a DXF file will be wrong, or. OGR. It could be edited manually, or the DXFENCODING. OGR in transcoding. The value of DXFENCODING should be an encoding name. CPLRecode i. e. DXF DWGCODEPAGE name. Using a DXFENCODING name of UTF 8 will avoid any attempt to recode the. Creation Issues. DXF files are written in Auto. CAD 2. 00. 0 format. A standard header everything. ENTITIES keyword is written from the GDALDATAheader. GDALDATAtrailer. Only one. Point features with LABEL styling are written as MTEXT entities based. Point features without LABEL styling are written as POINT entities. Line. String and Multi. Line. String features are written as one or more. LWPOLYLINE entities, closed in the case of polygon rings. An effort is. made to preserve line width and color. Polygon and Multi. Polygon features are written as HATCH entities. The dataset creation supports the following dataset creation options HEADERfilename Override the header file used in place. GDALDATA directory. TRAILERfilename Override the trailer file used in place. GDALDATA directory. Note that in GDAL 1. DXF files. The driver will scan them and only extract the needed. ENTITIES section. Block References. It is possible to export a blocks layer to DXF in addition to the. Ferrite Core Inductor Software Engineering there. DXF BLOCKs definitions. It is also possible to write INSERT entities if. To make this work the following. A blocks layer may be created, and it must be created before the. The entities in the blocks layer should have the Block field. Note, in GDAL 2. 2. Objects to be written as INSERTs in the entities layer should have a. POINT geometry, and the Block. Name field set. You may also set Block. Angle. Block. Scale, Block. OCSNormal and Block. OCSCoords see above under DXFINLINEBLOCKS. If Block. OCSCoords is set to a list of 3 real numbers, it is used. POINT. geometry is ignored. If a block name is already defined in the template header, that will be. The intention is that a simple translation from DXF to DXF with DXFINLINEBLOCKS. FALSE will approximately reproduce the original blocks and keep. INSERT entities as INSERT entities rather than exploding them. Layer Definitions. When writing entities, if populated the Layer field is used to set the. If the layer is not already defined in the template. Line Type Definitions. When writing LWPOLYLINE entities the following rules apply with regard to. Linetype definitions. Mgi Photosuite. If the Linetype field is set on the written features, and that Linetype. OGR style string existed.
