These tools are in Prepare group on the CAD Data tab on the Tools tab. The Rotate, Move, and Scale tools allow you to manipulate the dataset without using control points. In most cases, positioning your dataset before closer to its final position before adding control points can help you complete your task more efficiently. If you need to scale the file further to fit your map, see the section below. This shifts the dataset to fit the current view, regardless of where it is located. When this happens, zoom to the destination area and click Move To Display in the Prepare group on the CAD Data tab on the Tools tab. If the CAD drawing's origin coordinate (0,0,0) is significantly different than that of the map projection in your data frame, the CAD dataset may be added outside your data extent. Assigning a spatial reference is a best practice for producing an accurate transformation. If your CAD dataset does not have a coordinate system defined, you can apply one using the Define Projection tool in the Alignment group on the CAD Data tab on the Tools tab. To display the tab, select a child feature layer in the CAD group layer. The CAD Data tab is not visible when a CAD group layer is selected. Once you have georeferenced a CAD feature layer, you can add the other feature classes of that dataset to the map and they will be constrained by the same control points. Georeferencing a single CAD feature layer applies that transformation to the entire dataset. Choose a georeferencing layerĪll commands and tools on the CAD Data tab act on the CAD feature layer selected in the Contents pane. The methods you use and the order in which you perform them can vary depending on your data. The sections below are organized in the order of a typical georeferencing workflow. Click Georeference in the Alignment ribbon group. To display the tools, select a CAD feature layer in the Contents pane and click the CAD Data tab. You can use these interactive tools to reposition the data, as well as register control points to specific geographic coordinates. If you want a custom cross section profile you need to create one using the frame generator and the Inventor Authoring tools.Ī bonus in using the cross section definition is that you can also have a taper on the element i3 the one end is bigger than the other.The tools needed to georeference a CAD dataset in ArcGIS Pro are located on the CAD Layer tab. Unfortunately you cannot add to those default cross sections in Nastran IN CAD/ Inventor Nastran. When selecting the bar line element you have the following shape selections for your cross section.įor the Beam line element you have the above shapes as well as the following. Alternatively you can also specify the cross section. With the line element you can specify the properties of your line element like the area, area factors for shear and stress recovery coefficients. If you have created only the frame (2D and 3D lines) and do not want to utilise the frame generator you can create 3 types of line elements in Nastran, Bar, Beam and Pipe. This way Nastran will automatically assign a beam idealization to the part and you are then already half way to getting your analysis out. The best way to do this is create your frames with the frame generator. Line idealizations are used when creating frames. It is a 1D element with 6 degrees of freedom. Of the 3 idealizations or elements that created the line idealization solves the quickest.
