Synchronous sketches are used to create both synchronous and ordered features. Ordered sketches cannot be used to create a synchronous feature because while in the synchronous environment, ordered elements are not available for selection.
Synchronous sketches can only be selected when creating an ordered feature by using the “Select from Sketch” option in the Profile step.
In ordered modeling, fully-constrained sketches help you maintain predictability as you change a model by adding features and editing constraints. In synchronous modeling, sketches are consumed by the features that are based upon them, after which time the sketches no longer drive the shape or behavior of the model. So developing fully-constrained sketches is important in ordered modeling, but not in synchronous modeling. In synchronous modeling it is important that a sketch properly define a shape at the time the sketch is used to create new features; whether or not that shape is fully constrained does not determine the appropriateness of the shape. Since constraints defined on a sketch are consumed when the shape is used, they no longer constrain the resulting features.
Ordered features are driven by sketches. To edit the cross section definition of an ordered feature, edit the driving sketch.
The following are the methods available for editing a synchronous sketch which drives an ordered feature.
| Step 1. |
Turn on the display of the driving synchronous sketch. |
| Step 2. |
Select a sketch element to edit. You can move the selected sketch element and/or change the element properties on command bar. |
| Step 3. |
Edit sketch dimensions. |
Note:
You cannot edit or add synchronous sketch relationships using this method.
Note:
As the synchronous sketch is edited, the ordered feature dynamically updates.
| Step 1. |
Select the ordered feature to edit. |
| Step 2. |
Choose the Edit Profile command on the Feature Edit box.
|
| Step 3. |
The modeling environment switches to synchronous. You can now fully edit the synchronous sketch. |
| Step 4. |
When the synchronous sketch edits are complete, switch to the ordered environment to observe the feature edits. |
| Step 1. |
Select the ordered feature to edit. |
| Step 2. |
Choose the Dynamic Edit command on the Feature Edit box.
|
| Step 3. |
The driving synchronous sketch appears. Make edits to synchronous sketch. |
Synchronous sketch dimensions are not migrated to ordered features.
Synchronous sketches are not consumed when creating an ordered feature.
Synchronous sketches can drive ordered features.
Synchronous sketches appear while in the ordered environment.
Regions are disabled.
Synchronous sketches appear in the synchronous sketch style and colors.
When using the Select Tool in the ordered environment, synchronous sketch elements locate as individual elements.
Synchronous sketches can be moved using the steering wheel handle. The entire sketch moves (not single elements).
In the ordered environment, synchronous sketch geometry or relationships commands are not available.
Synchronous and ordered sketches cannot be copied while in ordered environment.
