Use the buttons in The Geometry Toolbar. You have buttons for geometric primitives as well as operations and conversions acting on geometry objects. See also
The Sketch Toolbar.
However the geometry is added to the sequence, define the node properties in the Settings window. In numerical fields you can enter expressions that contain parameters defined in
Parameters under
Global Definitions in the model tree to parameterize the geometry. Click the
Build Selected button (
) in the
Settings window to see the geometry objects that result.
Then browse to a filename and click Open. The file is scanned for geometry sequences having the right space dimension. If there is just one such sequence, its nodes are inserted into the geometry sequence after the current node. If the file contains more than one such sequence, a dialog box opens. Select the geometry sequence from the list of available sequences. Finally click
OK. The nodes in the selected sequence are inserted into the geometry sequence after the current node.
Then in the Settings window for
Import click
Browse. Navigate to the geometry file and double-click it. Then click
Import.
