Remove Trim Operation on Group of Parts from Propagation

Unread post by ken » Thu Dec 05, 2019 4:42 pm

I made a trim to a propagation of parts using the "sweeping curve" option. Is there anyway to undo the trim later on without having to manually remove each trim on each individual part?

Is there a better way to make a "trim" to multiple parts like this that will allow me to undo or modify the trim globally later on?

Thanks!

Hi

Can You delete this curve? Parts will give an error, but You select all errors and delete them all.
Last question - it's better to see full project to give better answer.

Is there any easy way to select all the errors? When I delete the curve, it creates an INVALID ELEMENTS SET but I will have to expand and delete each trim...

Yes.. sadly they are not grouped. I think here is no option to delete them all at once. Can You make contour without cutting later?

just my opinion but if you want a trim that is the same on all parts why didn't you just trim the template part that is the purpose of the repatition and template function :idea: :?:

The best that I can do right now is adjust the sketch curve where it is no longer trimming the parts. That "removes" the trim but doesn't break it. If there is another way to do this, I would really appreciate some insight!

Todd, Because each part of the repetition is being trimmed to a different length/shape. If I trim the template, they are all trimmed identical to it. (Left hand side of the pic shows the trim line of each rib).

maybe Serial copy with driving points like the above video is a better design approach then if they are all different.

Todd, Thanks for the suggestion. I hadn't considered using serial copy in this instance. I will have to think about that. I am trying to balance between a robust model I can easily manage changes on and the fact that this is a one time project (interior of a performing arts center) and I may not even need to undo the trim later. I was hoping there was some trick I was missing that would allow a global "undo" of a trim later on.

I did use the serial copy in another part of the project to make this assembly that has dynamically positioned half-lap joints centered in plywood ribs that follow a swept profile and it worked awesome but took a pretty big time investment to get it figured out and working.
