edit sketch hides components and moves them to an ealier stage

[Anonymous]

Hi,

 

I'm trying to understand the workflow to create a case.

I have sketch that resides inside his own component, it was created at an early stage (first image), and now I want to edit.

As you can see it was created before  the insertion of some parts and the creation of some joints.

So, when I go to edit it...some components disappear, and some revert (temporally) to an early position (3rd image), then I can't size the case properly.

I tried to:

1. Move components using the timeline, so the are all inserted before the sketch>>> unable to move
2. Move the sketch to a later stage (all components and modification)>> unable to move

Obviously the case in not very complicated, and it can be deleted easily and redrawn. But I can imagine some scenarios which this would be a real pain.

I guess I'm trying to do some bottom up design, but I'm missing the correct workflow so I can see all parts in their current state...Any ideas?

Thanks

Can you please share the model so the forum users can troubleshoot your issue?

The file is empty!  It is only 20KB so something must have happened.  You open you assembly, Select Export from the File menu, save the file to your hard drive and then attach it as you did before.  If you did this, please try again.  Maybe you can test it before attaching it.

Yes that's what I did, let's see now...

I hate to be dumb but all the linked components are Direct Modeled, they do not have any sketches. Can you do a Screencast to show what you need for a better screen capture with markups.  You mention a third image, there are only two in your original post.

Sry..My bad, I did not explain properly

Please see my "screencast":

• SreenCast

As you can see, as soon as I start editing the sketch, the screen "reverts" to an earlier point in the history. (I guess this is the normal behaiviour, as the sketch was created before some components were inserted and layed out.)

Normaly, I create a sketch for a case to get a sense of the layout of the components inside. Then, once I got everything more o less where it suppose to be, then I go back to edit the sketch.

Is there a way to disable, override or get rid of this shared history, while maintaining the history of each part?.

Or whats the best way to aproach this, meaning edit a sketch without loosing the overall perspective? (assembly)

As a work around I tried to move the sketch upstream, or the componenets that disappeared down stream.

Notes:

• If you open the file, there is a component called "case", and inside "sketch3"
• Sry, I have no clue how to upload a Screencast

Thanks for the much clearer explanation.  The easiest way to accomplish what you want is to follow the process outlined in my Screencast.  You will get a "Warning" during part of the process but it is OK, you can continue with it.  The warning is caused because you based your workplane, created to sketch your case on, from one of the other components in the assembly.  Learn to go back to the origin planes to create new workplanes and this will never happen again.

By the way, Screencasts are easy.  When you want a video on how to create and attach it to your forum question, let me know.  Send me a private message if you want it, hover over my handle (name) and you will see Send Private Message.

Edit: I forgot to mention in the video.  After inserting the case back into your assembly, without moving it, and then breaking the link, you probably should either ground it again or add some assembly joints to maintain its position.
