This script imports 2d and 3d geometery from DXF files. It supports DWG format too, with help of an external converter. Supported DXF format versions: from (r2.5) r12 up to r2008. Enhanced features are: - configurable object filtering and geometry manipulation, - configurable material pre-processing, - DXF-code analyze and reporting. Supported DXF r12 objects: LINE, POINT, SOLID, TRACE, TEXT, INSERT (=block), MINSERT (=array of blocks), CIRCLE, ARC, 3DFACE, 2d-POLYLINE (=in plane, incl. arc, variable-width, curve, spline), 3d-POLYLINE (=non-plane), 3d-POLYMESH, 3d-POLYFACE, VIEW, VPORT XREF (External Reference). Supported DXF>r12 objects: ELLIPSE, LWPOLYLINE (LightWeight Polyline), SPLINE, (todo v1.13) MLINE, (todo v1.13) MTEXT Unsupported objects: DXF r12: DIMENSION. DXF>r12: GROUP, RAY/XLINE, LEADER, 3DSOLID, BODY, REGION, dynamic BLOCK Supported geometry: 2d and 3d DXF-objects. Curves imported as Blender curves or meshes optionally. Supported layout modes: "model space" is default, "paper space" as option (= "layout views") Supported scene definition objects produced with AVE_RENDER: scene: selection of lights assigned to the camera, lights: DIRECT, OVERHEAD, SH_SPOT, (wip v1.13 import of AVE_RENDER material definitions) Hierarchy: Entire DXF BLOCK hierarchy is preserved after import into Blender (BLOCKs as groups on layer19, INSERTs as dupliGroups on target layer). Supported properties: visibility status, frozen status, thickness, width, color, layer, (todo v1.13: XDATA, grouped status) It is recommended to use DXF-object properties for assign Blender materials. Notes: - Recommend that you run 'RemoveDoubles' on each imported mesh after using this script - Blocks are created on layer 19 then referenced at each insert point. - support for DXF-files up to 160MB on systems with 1GB RAM - DXF-files with over 1500 objects decrease import performance. The problem is not the inefficiency of python-scripting but Blenders performance in creating new objects in scene database - probably a database management problem. """ """ History: v1.0 - 2007/2008/2009 by migius planned tasks: -- (to see more, search for "--todo--" in script code) -- command-line-mode/batch-mode -- in-place-editing for dupliGroups -- support for MLINE (is exported to r12 as BLOCK*Unnamed with LINEs) -- support for MTEXT (is exported to r12 as TEXT???) -- blender_object.properties['dxf_layer_name'] -- better support for long dxf-layer-names -- add configuration file.ini handles multiple material setups -- added f_layerFilter -- to-check: obj/mat/group/_mapping-idea from ideasman42 -- curves: added "fill/non-fill" option for closed curves: CIRCLEs,ELLIPSEs,POLYLINEs -- "normalize Z" option to correct non-planar figures -- LINEs need "width" in 3d-space incl vGroups -- support width_force for LINEs/ELLIPSEs = "solidify" -- add better support for color_index BYLAYER=256, BYBLOCK=0 -- bug: "oneMesh" produces irregularly errors -- bug: Registry recall from hd_cache ?? only win32 bug?? -- support DXF-definitions of autoshade: scene, lights and cameras -- support ortho mode for VIEWs and VPORTs as cameras v1.12 -
