2D Projection by External Model

The mode of constructing a projection by a model from an external file is useful when working with complex 3D models and assemblies, in which cases you can significantly save the computational resources by avoiding the 3D model recalculation. When creating a 2D projection, the system takes from the external file only geometrical data saved in this file. It is also possible, if necessary, to compose a single drawing from different 3D models (different versions, individual fragments, etc.).

The option to select an external file to construct a projection is available in the command's automenu:

<F>

Select File with 3D Model to create Projection

If the user calls the command to create a 2D projection, but no 3D model is present in the current document, then at the beginning this will be the only option in the automenu. Upon calling this option, the standard dialog window to select the file will appear. Once you selected a file with the 3D model, all the rest of the options to construct the projection would become available in the automenu. After that, the projection is constructed as usual. At the same time, there are restrictions on selecting elements to map (project). In this case, it is always the entire 3D model contained in the selected file that will be mapped (projected).

If it is necessary to create several projections based on an external file, you do not have to select it over each time. When constructing related views (a related standard view, cuts and sections, arrow views), the data about the 3D model is automatically accessed from the initial projection.

The information about the used external file is recorded in the 3D model tree next to the 2D projection name. If you right-click on the 2D projection , then you will see in the contextual menu the Open command, which open the external file used for projection. The name of the file used to construct the 2D projection can be found on the Elements tab of the 2D Projection Parameters window.

The mode of constructing a projection based on the model from external file can be also activated by setting the method of projection From File in the group of the parameters window Elements for Bodies and operations. Simultaneously, the option will be activated automatically.
