Updating Drawings
In Creo, the 3D model and the drawing that references the model are associative. That means that changes you make in the 3D model appear in the drawing, and that changes you make in the drawing appear in the 3D model.
This exercise includes the following tasks:
Change the 3D model
View changes to the 3D model in the drawing
Update the drawing—references
Update the drawing—dimensions
Set the dimension properties
Observe the association between the 3D model and the drawing
Change the 3D model
In this task, you will make a few changes to a 3D model so that you can view the changes later in the drawing.
1. In Creo Parametric, set the working directory to <downloaded files location>, and open sp155051rh.prt.
2. To set the model view, click Saved Orientations on the in-graphics toolbar, and select VIEW 1.

View changes to the 3D model in the drawing
In this task, you observe how the changes you make in a 3D model using Creo Flexible Modeling are propagated to the drawing that references the model.
1. Open the drawing sp155051rh.drw. The drawing opens, with the Flexible Modeling features that you created highlighted in green.
A warning message appears stating that Flexible Modeling features have been detected, that some of the annotations might be outdated, and they should be reviewed and updated.
2. Read the warning and click Review. The Highlight by Attributes dialog box opens.
3. To redraw the current view, on the in-graphics toolbar, click Repaint. The drawing is updated, and the highlighting disappears.
4. To highlight in the drawing the Flexible Modeling changes that you made previously in the model, in the Highlight by Attributes dialog box, next to Flexible modeling features, click Highlight.
5. In the Highlight by Attributes dialog box, under Dimension type:
a. Clear the Owned by a model check box.
b. Clear the Created, non-associative check box.
c. Click Apply.
6. Zoom in on the bottom middle drawing. The dimensions where changes were made in the 3D model are now highlighted.
7. Observe the highlighted dimensions while you click Update references. The updated references become highlighted. Some of the references have been reassigned.
8. In the Highlight by Attributes dialog box:
a. Select the Owned by a model check box.
b. Clear the Created, associative check box.
c. Click Apply.
d. Close the Highlight by Attributes dialog box.
The R10 dimensioning is out of date because the radii of the model have been updated using Flexible Modeling. The references in the drawing are now outdated, and the R10 dimensioning is not pointing to any references.
Update the drawing—references
In this task, you update the dimensioning in your drawing to show the changes that you made in the 3D model using Creo Flexible Modeling. You will continue from where you left off in the previous task. The R10 dimensions are out of date, and you will update them to the changed references.
1. In the drawing, click the Annotate tab.
2. In the Annotations group, click Dimension. The Select References dialog box opens.
3. Point over the rounded edge where one of the R10 arrows should be, until the line highlights.
4. Click the highlighted edge to select the location where the tip of the dimension arrow should be. A new dimension appears in gray.
5. Move the cursor around and observe what happens to the dimensioning.
6. Middle-click to place the dimension. The dimension is highlighted.
7. Click the dimension to remove the highlighting.
8. Repeat the steps for the second R10 dimension:
a. Point over the round where the second R10 arrow should be, until the line highlights.
b. Click the light green edge to select the location for the tip of the dimension arrow.
c. Middle-click to place the dimension.
d. Click the dimension to remove the highlighting.
9. Close the Select References dialog box. Now the R10 dimensions are pointing to updated references.
10. To remove the outdated R10 dimensions:
a. Select one of the outdated R10 dimensions, and then hold down the CTRL key while you select the second outdated R10 dimension.
b. Right-click anywhere in the graphics window, and choose Delete from the shortcut menu. The outdated dimensions disappear.
