How to Draw in Datum Plane Abaqus

68.half dozen.1 Using the sketch method to partition faces

You can partition selected faces by sketching the geometry of the partition using the Sketcher. You use the Sketcher when you want to create a sectionalization whose shape cannot be achieved with any of the other partition tools. Sketching a segmentation offers other advantages:

• You tin can apply the Feature Manipulation toolset to modify the sketch if you desire to alter the shape or the position of the sectionalization.

• You can dimension the sketch precisely, and you can utilize the Feature Manipulation toolset to modify the dimensions.

If the faces to be partitioned are planar and lie in the same plane, you can sketch directly on that airplane. Your sketch can extend beyond the boundaries of the selected faces, but the partition will not extend beyond the border of the faces. The following effigy illustrates a sketched sectionalization on a planar face:

If any of the faces to be partitioned are non-planar or do not lie in the same airplane, y'all must select a planar face up or datum plane on which to sketch. Abaqus/CAE creates the partition past projecting the sketch onto the faces to be partitioned. You can specify the direction of the project and the altitude of the projection, normal to the sketch plane. The following figure illustrates a sketched partition on a not-planar face using the projection of a sketch drawn on a datum plane:

To segmentation faces using the sketch method:

1. From the main menu bar, select .

   The Create Partition dialog box appears. Abaqus/CAE displays prompts in the prompt area to guide y'all through the procedure.

   Tip: You can likewise employ the sketch method to sectionalisation faces using the tool, located with the partition face tools in the module toolbox. For a diagram of the partition tools in the toolbox, see "Using the Partition toolset," Section 68.2.

2. From the Type radio buttons at the meridian of the dialog box, choose Face .

   The Method list displays the methods that you can use to partition a face.

3. From the list of methods, select Sketch .

   If the part or assembly contains only 1 face, Abaqus/CAE enters the Sketcher.

4. If the part or assembly contains more than than one confront, select the faces to segmentation and click mouse button 2. You can apply a combination of elevate select, [Shift] +Click, [Ctrl] +Click, and the bending method to select more than one face to partition. For more than information, see "Selecting objects within the current viewport," Section 6.2.

   Tip: If you are unable to select the desired faces, y'all can use the Choice toolbar to change the selection behavior. For more information, see "Using the selection options," Section half-dozen.3.

   • If the part or associates is two-dimensional or axisymmetric, Abaqus/CAE enters the Sketcher and highlights the selected faces.

   • If the part or assembly is three-dimensional and the selected faces are planar, select an edge and the orientation of the edge on the Sketcher grid. The edge must not be perpendicular to the sketch airplane. By default, the selected edge will appear vertical and on the correct side of the Sketcher grid. To choose a unlike orientation for the edge, click the pointer on the right side of the dialog box and choose an orientation from the list that appears.

     Tip: If the office or assembly does not take an border that will provide the desired orientation, you can create a datum axis. You tin can then select the datum axis to command the orientation of the part on the Sketcher filigree.

     Abaqus/CAE highlights the selected edge, enters the Sketcher, and rotates the part until the selected planar face or datum plane aligns with the plane of the Sketcher grid and the selected edge aligns with the grid in the desired orientation. Abaqus/CAE highlights the selected faces.

   • If the part or associates is three-dimensional and the selected faces are non-planar or exercise not lie in the same plane, do the following:

     1. Select a planar face or a datum plane on which to sketch. Abaqus/CAE highlights the selected confront.

     2. From the buttons in the prompt area, select a method to determine how far Abaqus/CAE projects the sketch normal to the sketch plane. The partitioning is created wherever the projected sketch extends through the selected faces. The three methods are illustrated in the post-obit figure:

        

        • If you selected the Through All method, Abaqus/CAE asks y'all to choose which direction the sketch will be projected.

        • If you lot selected the Enter Value method, Abaqus/CAE asks you to choose the distance and management that will exist used to projection the sketch. The default distance that Abaqus/CAE provides generates a sectionalization that extends completely through the selected faces (resulting in the same partition as selecting Through All ). The Feature Manipulation toolset allows you to alter the project distance later on y'all create the partition.

        • If you lot selected the Select Indicate method, Abaqus/CAE asks you to choose the indicate to which the sketch will be projected; the point defines both the direction and the projection altitude.

     3. Select an edge and the orientation of the border on the Sketcher grid. The edge must not be perpendicular to the sketch plane. By default, the selected edge volition appear vertical and on the right side of the Sketcher grid. To choose a unlike orientation for the edge, click the arrow on the right side of the dialog box and choose an orientation from the list that appears.

        Tip: If the part or associates does not have an border that volition provide the desired orientation, you tin can create a datum axis. You tin can and then select the datum axis to control the orientation of the part on the Sketcher grid.

        Abaqus/CAE highlights the selected border, enters the Sketcher, and rotates the office until the selected planar face or datum plane aligns with the plane of the Sketcher filigree with the projection direction into the screen and the selected edge aligns with the grid in the desired orientation. Abaqus/CAE highlights the selected faces.

5. Utilize the Sketcher to sketch the partition. From the principal menu bar, click Done to indicate you have finished sketching the partition.

6. In the prompt area, click Create Partition .

   Abaqus/CAE creates the sectionalisation.
