sketch not updating when bodies moved

[Anonymous]

If I make a sketch on a body face that has other bodies touching it, those bodies are shown on the sketch. If I move one of those bodies later, the view when the sketch is edited shows the orginal position of the bodies, not the new position. Why is that? I thought the concept was to allow moving elements on a body by editing a sketch. That's hard to do if the sketch doesn't reflect the current state of the design.

Hi @Anonymous, thanks for the post.

If you are moving bodies, then you will have a "Move" feature in your timeline.  Editing the sketch "rolls back" the timeline to the point at which the sketch was created.   Because that is before the Move feature, the bodies will be in the position that they were in when the sketch was created.  The Timeline takes you "back in time" to when the element you are editing was created.

If you really want the bodies to be moved when you edit the sketch, drag the Move feature before the sketch (assuming that there are no dependencies preventing this).

Hope this helps,

Well, perhaps there is some other way to do this? I expected the Sketch to reflect what I see on the screen before I entered sketch mode. If I come back to a design a year later and need to move a hole on a part, a lot could have changed since the Sketch was created.

Hey there, this is definitely an interesting subject with a lot of ways to go about it.  Besides creating the sketch and body in the desired location to begin with, I would say one of the most interesting ways to move everything, including sketches, while maintaining that location when editing a moved sketch, is the following.  First be sure that your sketch is in a component, either by creating a new component and activating it so a new sketch goes into it, or creating a new component after the sketch is created and then dragging the sketch into the new component, which is normally allowed and also brings all bodies created from the sketch into the new component as well.  Then when you want to move the body and sketch, do a Component Move, after which a snapshot button will appear in the upper right of the screen.  This places an update/marker of new component position into the timeline.  Finally, to make this new position exist before the sketch was created in the timeline, you need to first insure the component creation event (a white cube) exists before the sketch creation event in the timeline.  If not drag it back in time sufficiently.  Then you can drag the snapshot event to before the sketch as well, and presto!  Note that it's possible to also Combine components together, so fillets etc. can be performed between them.

Good luck!
