Creating Geometry

There are many different ways to create geometry in HyperMesh which include importing from external CAD models, as well as creating new geometry from scratch. The methods used to create a particular geometry depend on both the entities available for input and the level of detail required. The following methods are available for creating geometry in HyperMesh:

•	xyz - Creates by specifying (x,y,z) coordinates (Nodes panel).

•	on geometry - Creates at graphically selected locations on points, lines, surfaces and planes (Nodes panel).

•	arc center - Creates nodes at the center of the arc that best approximates the input set of nodes, points or lines (Nodes panel).

•	extract parametric - Creates nodes at parametric locations on lines and surfaces (Nodes panel).

•	extract on line - Creates evenly spaced or biased nodes on a selection of lines (Nodes panel).

•	interpolate nodes - Creates evenly spaced or biased nodes by interpolating between existing nodes in space (Nodes panel).

•	interpolate on line - Creates evenly spaced or biased nodes by interpolating between existing nodes on a line (Nodes panel).

•	interpolate on surface - Creates evenly spaced or biased nodes by interpolating between existing nodes on a surface (Nodes panel).

•	intersect - Creates nodes at the intersection of geometric entities: lines/lines, lines/surfaces, lines/solids, lines/planes, vector/lines, vector/surfaces, vector/solids and vector/plane (Nodes panel).

•	temp nodes - Creates nodes by duplicating existing nodes or creating nodes on existing geometry or elements (Temp Nodes panel).
