Creating 1D Mesh Parts

1D or beam mesh can be deleted and/or added to parts manually.

This task shows you how to add beam mesh to a Generative Shape Design CATPart.

Open the sample47.CATAnalysis document from the sample directory.

1. Click the Beam Mesher icon

2. Select the beam to be meshed.

The Beam Meshing dialog box appears.

3. Enter the desired Element size in the Beam Meshing dialog box. In this particular case, enter 3mm.

4. Activate the Sag control option in the Beam Meshing dialog box.

New options are available under the activated Sag control option.

	`Min size`: set the minimum element size
	`Sag`: set the mesh sag

5. Click OK in the Beam Meshing dialog box.

The 1D Mesh.1 feature now appears in the specification tree. Note that now the corresponding Beam Property is missing.
For more details on how to add this Beam Property, see task called Creating Beam Property.

To apply a restraint, a load or a connection to one extremity of a beam, you need to first put the point that were possibly created at the extremity of this beam, in order to build the wireframe, into the Hide mode. As result, to apply the above mentioned specifications, you will select the extremity of the wireframe and not the hidden point (small cross in the 3D view) as this point is not linked to the mesh.

You cannot apply beam properties and 1D mesh parts on geometry included in a sketch.
