CrossSection

Create a 2D geometry from a cross section of a 3D geometry.

Syntax

model.geom(<tag>).create(<ftag>,"CrossSection");

model.geom(<tag>).feature(<ftag>).selection("input");

model.geom(<tag>).feature(<ftag>).set(property,<value>);

model.geom(<tag>).feature(<ftag>).getType(property);

Description

In a 2D geometry, use model.geom(<tag>).create(<ftag>,"CrossSection") to create 2D geometry objects by intersecting 3D geometry objects with a work plane. Select the work plane using the workplane property, whose value is the 3D sequence’s tag followed by a slash and the work plane feature’s tag, for example geom1/wp1. By default, you get the last work plane in the last 3D geometry.

In a 2D sequence of a work plane feature, use model.geom(<tag>).feature(<wptag>).geom().create(<ftag>,"CrossSection") to create 2D geometry objects by intersecting 3D geometry objects with the work plane.

By default, you get the intersection for all 3D objects that were generated by the features preceding the work plane feature. To select a subset of these objects, set the intersect property to selected, and use the property input to select the 3D objects to intersect.

The following properties are available:

Property	Value	Default	Description
absrepairtol	double	model.geom(<tag>).absRepairTol()	Absolute repair tolerance.
contributeto	String	none	Tag of cumulative selection to contribute to.
input	Selection	empty	Selection of objects to intersect.
intersect	all | selected	all	Intersect all objects or selected objects.
repairtol	double	model.geom(<tag>).repairTol()	Relative repair tolerance, relative to size of each input object.
repairtoltype	auto | relative | absolute	model.geom(<tag>).repairTolType()	Repair tolerance type: automatic, relative, or absolute.
selresult	on | off	off	Create selections of all resulting objects.
selresultshow	all | obj | dom | bnd | pnt | off	dom	Show selections, if selresult is on, in physics, materials, and so on; in part instances; or in 3D from a plane geometry. obj is not available in a component’s geometry. dom, bnd, and edg are not available in all features.
workplane	String		Work plane to intersect with.

Example

Create a work plane though the axis of a torus. In a 2D axisymmetric geometry, create the cross section of the torus using the work plane. Note that the last run() command removes the part of the cross section that falls in the region r<0.

Code for use with Java

Model model = ModelUtil.create("Model");

model.modelNode().create("mod1");

GeomSequence g1 = model.geom().create("geom1", 3);

g1.create("tor1", "Torus");

g1.run("tor1");

g1.create("wp1", "WorkPlane");

g1.feature("wp1").set("planetype", "circularedge");

g1.feature("wp1").selection("circedge").set("tor1", 15);

 

model.modelNode().create("mod2");

GeomSequence g2 =model.geom().create("geom2", 2);

g2.axisymmetric(true);

g2.create("cro1", "CrossSection");

g2.run("cro1"); // Two circles

g2.run(); // One circle

Code for use with MATLAB

model = ModelUtil.create('Model');

model.modelNode.create('mod1');

g1 = model.geom.create('geom1', 3);

g1.create('tor1', 'Torus');

g1.run('tor1');

g1.create('wp1', 'WorkPlane');

g1.feature('wp1').set('planetype', 'circularedge');

g1.feature('wp1').selection('circedge').set('tor1', 15);

 

model.modelNode.create('mod2');

g2 = model.geom.create('geom2', 2);

g2.axisymmetric(true);

g2.create('cro1', 'CrossSection');

g2.run('cro1'); % Two circles

g2.run; % One circle
