Create a 1D mesh

1. Click 1D Mesh .

2. Select the object to mesh. If you select a curve or polygon edge, the software generates a 1D mesh along that curve or edge. If you select a polygon face, the software generates a 1D mesh on each edge of the face.Note: To create 1D elements between selected nodes, points, or mesh points, use the 1D Connection command. See 1D Connection.

3. Make sure the displayed directions of the selected curves or edges are consistent. The temporary arrow graphics should point in the same direction along a chain of edges or curves. If the directions are not consistent, hold down the Shift key and deselect the edges where the previewed direction is incorrect and either:Select the Auto Chain Selection option and re-select the edges. The software uses the direction of the first edge or curve you select to set the direction of the other edges or curves in the selection.Re-select the edges, making sure to click your mouse closest near the opposite end of the curve.For more information, see Ensuring consistent 1D element orientation during mesh creation.

4. Select an element type.

5. Specify the destination mesh collector:Select Automatic Mode to have the software create a new destination mesh collector for you. This mesh collector uses the default physical properties and inherits the material and cross section properties of the model.To use an existing mesh collector, clear the Automatic Mode check box and select a collector from the Mesh Collector list.To create a new destination collector, clear the Automatic Mode check box and click New Collector .For steps to define cross section dimensions, orientation, and offsets, see Beam cross section workflow.

6. From the Mesh Density by list, select either Number or Size and enter a value:If you select Number, enter the number of elements. If you enter 9 for example, and select an edge, the software will distribute nine elements along the selected edge.If you select Size, enter a size in model units.

7. Choose Apply or OK. 1D elements are built along or between the objects you selected for meshing.
