![]() In AutoCAD, the Quick Select tool (QSELECT command) can be used to quickly select unwanted object types in a file. There are several commands used to ‘clean’ a DXF file and reduce its size: Remove and/or Convert Non-Import Entities If the intended entities do not occupy the entire window, there are likely unintended entities in the drawing. View should be of intended entities filling the model window. ![]() Zoom to Extents (Z-enter, E-enter) to check for extraneous entities in the drawing. Replacing complex entities with simple entities is also recommended, for example, in the image above, replacing the seats with a single entity will reduce the overall file size significantly and simplify the drawing. Remove these entities from the drawing (e.g., lobby, doors, and bathrooms), select and ERASE (AutoCAD). Many drawings contain entities that are not needed for design work in MAPP 3D. Imported 2D Plan and Longitudinal Section Drawings Arranged in a 3D Fileįor best application performance, the size of the imported DXF should be kept as small as possible, though files of 20 Mb or larger can be imported. This enables the designer to add Primitives in MAPP 3D representing seating areas and to select them for prediction. The origin for both images must be in the same place, downstage-center for example. The plan file is oriented flat on the XY plane, and the longitudinal section is oriented flat on the XZ plane. If only 2D DXF files are available, they can be arranged in a 3D file in an orientation that approximates a 3D file, as shown in the figure below. If the DXF file is two-dimensional, all objects should be parallel to one of the three planes (XY, XZ, or YZ), which translate to Plan, Longitudinal Section, and Transverse Section views. Step 6: Check the scale of the drawing imported into MAPP 3D: select the Distance Tape Measure tool and measure the distance between two points in the imported drawing and confirm the measurement matches the original drawing. Step 4: Enter Axis Limits or select Import Graphics Drawing Limits if the limits were set in the drawing. Step 3: From the Import Graphics window, choose the Distance Unit used in the source file (e.g., if the DXF drawing units are feet, select feet). Step 2: Select FILE > IMPORT, choose DXF, and choose the file to import. Drawing preparation details are below this section. Step 1: Prepare the drawing for import in AutoCAD and save it using the 2013 DXF format. DXF files usually need to be edited to ensure they are imported into MAPP3D correctly and in a way that makes them easy to work with. Skip down this page to Import SKP Files section.īoth 2D and 3D AutoCAD DXF files can be imported into a MAPP3D project. We can usually import drawings for users in a short period of time. If drawing software is not available, please contact us: and select Technical Support. It is essential to work from an accurate venue model when designing a sound system for a given space. 2D DXF, 3D DXF, and SKP files can be imported into MAPP3D, which aids in the creation of an accurate venue model.
