Assign a name to a specific position (that is, the Mate degree of freedom values, and absolute transforms for instances with no Mates) of the assembly and switch to a particular named position easily at any time. Keep in mind that the Mate values are relative and are able to be satisfied even if both sides of the Mate have moved.
- Click .
Click and drag to move parts to the positions desired (optionally using mate positioning, limits, etc). Note that Mates are not required in order to create Named positions and the Named position references the position of every part in the Assembly.
- Enter a name for the position.
- Click to add that Named position.
- Repeat to create more named positions.
- Click .
- Select a named position from the drop down menu:
If the position is unable to be loaded, a message that some Mate values could not be applied appears.
Reasons a position may fail to load might include:
- Deletion or modification of a mate or limit
- Deletion or modification of a part
In the event something has changed about the named position, for instance, a part is no longer in the assembly (and the named position), or you simply want to tweak a position, you can:
- Click to open the Named position dialog.
- Select the named position you wish to change.
- Make the necessary changes in the model.
- Click to save the new model positions with the selected Named position.
To rename a selected Named position:
- Select the Named position you wish to rename.
- In the New position name field, type a new name for the selected position.
- Click the plus sign button to add the Named position with the new name.
- Delete the Named position with the old name by clicking (Remove position).
- Setting up named positions beforehand may aid in effectively changing positions for modeling in context.
- The positioning of Tangent and Fastened Mates are not impacted in named positions. Fastened Mates always continue to work, however, Tangent Mates may rely on a parameter that has changed and may not work in all cases.
- If a named position fails, you may have made a change with which the named position is unable to render. Revert to an earlier point in the document history, or delete the named position and create a new one.
