Data interchange of AutoCAD and 3DS

Although 3DS has a powerful three-dimensional modeling function, the most commonly used three-dimensional modeling tool in the field of architecture still prefers AutoCAD. This is because the 3DS is just a visual tool, its drawing standard is "look is right", and for architectural design, often need precise positioning, so we are generally in AutoCAD to establish a model, through the transformation of DXF file into 3DS.

In AutoCAD, we usually set the drawing unit to mm (mm) according to the actual size, after entering 3DS, its drawing unit and AutoCAD are one by one corresponding, some people like to set the drawing units in 3DS to millimeters, but in fact, even without setting, it will not affect the matching of the drawing units. Sometimes because the data volume of the whole three-dimensional model is too large, want to divide the model into 3DS, or some part of the model needs to be modified in AutoCAD and then combined into 3DS, it should be noted that: after the transfer into the DXF file, you must not modify the drawing unit and do not move the entity in the diagram, So long as in the AutoCAD entity also does not have the position change, can be in the AutoCAD respectively draw entity merges (inserts) in the 3DS to carry on the combination, the position also can be very accurate.

If you need to draw three-dimensional entities in 3DS or make exact copies of the entities, move, and so on, you can open the snap (activate the view and press the S key), but note that SNAP controls only the activated window, where the yellow "S" character appears in the upper-right corner of the interface, indicating that the operation in the window is snap. Snap spacing can be views/drawing in the dropdown menu
