Moving Geometry
In this exercise, you learn to move geometry using a dragger, and using dimensions. You explore different ways to attach the moved geometry to the model. This exercise includes the following tasks:
Move using the dragger—basic
In this task, you will move geometry with
Move using Dragger.
1. In Creo Parametric, set the working directory to <downloaded files location>, and open sp115050.prt.
2. To disable all datum display filters, click
Datum Display Filters on the in-graphics toolbar, and clear all the check boxes.
3. To set the display style, click
Display Style on the in-graphics toolbar, and select
Shading With Edges.
4. To set the model view, click
Saved Orientations on the in-graphics toolbar, and select
VIEW 1.
5. Click the Flexible Modeling tab.
6. In the graphics window, select the blue surface, parallel to the top surface of the non-cylindrical hole.
1. Blue surface
7. To select the entire cut of which the selected surface is a part, along with smaller surfaces that intersect it, in the
Shape Surface Selection group, click
Cuts.
8. To view the selected surfaces more closely, click
Saved Orientations, and select
VIEW 2.
9. To select the desired geometry:
a. Press and hold down the CTRL key while you select the yellow outer surface of the cylinder.
b. To select the entire boss of which the selected surface is a part, in the
Shape Surface Selection group, click
Boss.
Now all the geometry that you want is selected.
10. To view the front of the model, click
Saved Orientations, and select
FRONT.
11. To select the type of move, in the
Transform group, click the arrow under
Move, and select
Move using Dragger. The
Move tab opens.
12. To move the geometry, drag the handle of the dragger to the position shown below.
13. Click
to accept the feature.
Move by dimensions
In this task, you will use
Move by Dimension to make the model shorter by moving a surface, three holes, and their associated geometry.
1. Click
Saved Orientations on the in-graphics toolbar, and select
VIEW 3.
2. In the lower right corner of the Creo window, ensure that the selection filter is Regions and Surfaces.
3. To select the geometry to move (three holes on the left side of the model, their associated geometry, and the left side of the model):
a. Select the planar surface of the upper left hole.
b. To select the entire cut of which the selected surface is a part, along with smaller surfaces that intersect it, in the
Shape Surface Selection group, click
Cuts.
c. Press and hold down the CTRL key while you select the planar surface of the middle left hole, and then click
Cuts.
| Alternately, to use the mini toolbar, hold down CTRL while you select the surface, and then temporarily release the CTRL key to click Cuts on the mini toolbar. |
d. Continue holding down the CTRL key while you select the planar surface of the lower left hole, and then click
Cuts.
e. Continue holding down the CTRL key while you select the red surface on the left side of the part, next to the holes.
4. In the
Transform group, click the arrow under
Move, and select
Move by Dimension. The
Move tab opens.
5. To set the dimension, on the Move tab, click the Dimensions tab, and do the following:
a. To select the references for the dimension, click the References collector, and then press and hold down the CTRL key while you select the left side surface of the model, and the right side surface.
1. Side surfaces
b. To set the dimension value, click the Value collector, and change the value from 228 to 220.
Notice how the holes remain in position during the move.
6. Click
to accept the feature.
Move using a dragger, use bounding edges, and navigate multiple solutions
In this task, you will move geometry with
Move using Dragger, use bounding edges to drive the solutions, and navigate multiple solutions.
1. Click
Saved Orientations on the in-graphics toolbar, and select
VIEW 4.
2. Select the purple surface.
3. To select the entire boss of which the selected surface is a part, along with smaller surfaces that intersect it, in the
Shape Surface Selection group, click
Bosses.
4. To select the type of move, click the arrow under
Move, and select
Move using Dragger. The
Move tab opens, and the dragger appears on the selected geometry.
5. To place the dragger, click the edge to the right, as shown:
6. To move the selected geometry:
a. Drag the handle of the dragger downwards, toward the larger boss in the bottom right corner.
b. In the graphics window, click the offset value and edit it to 32.
Notice how the solution automatically recreates the rounds, even though the topology under the boss has changed.
7. To select bounding edges:
a. Click the Attachment tab.
b. Click the Bounding edges collector.
c. Press and hold down the CTRL key while you select the two tangent edges where the top round connects to the top planar surface, and that pass through the preview of the moved geometry.
8. To see what other solutions are available, on the Attachment tab, click Next. The system uses the surfaces adjacent to the bounding edges to extend and intersect the moved geometry in the various solutions.
9. To select different bounding edges:
a. To remove the selected bounding edges, in the Bounding edges collector, right-click and choose Remove All.
b. Press and hold down the CTRL key while you select the two tangent edges where the top round connects to the vertical planar surface, parallel to the two edges you selected previously, but farther down.
10. To see what other solutions are now available, on the Attachment tab, click Next. Now the vertical surface below the selected edge is extended.
11. Use this solution, and click
.
Attachment options
In this task, you will get to know different types of attachment options in the context of a move using a dragger. During a move in
Creo Flexible Modeling, click
to create side surfaces to fill the gap between the moved surface and the neighboring geometry.
1. Click
Saved Orientations on the in-graphics toolbar, and select
VIEW 5.
2. Select the orange surface.
3. To select the type of move, click the arrow under
Move, and select
Move using Dragger. The
Move tab opens.
4. To place the dragger, click the edge where the horizontal and vertical surfaces connect.
5. To move the selected geometry:
a. Drag the handle of the dragger to move the geometry to the right.
b. Edit the offset value to 3.
6. Click
to activate the attachment options.
7. Click
again to view a different attachment option.
8. Click
to accept the feature.
9. Save and close the model.
