Help Understanding Component Timeline Relationships

chrisqx2 — Tue, 28 Sep 2021 18:18:12 GMT

Been using Fusion as a hobbyist user for years and thought I was quite proficient, until I encountered this small detail regarding component editing which I cannot seem to find an answer for, so my first post.

All components are children of the assembly. None are linked.

Problem: I noticed interference between components A & B.

Rolled back Component A's timeline to edit the offending sketch, and Component B ceased to exist.

I understand that all components timelines are contiguous under the assembly timeline, thus rolling back component A's timeline brought me to a point in time before component B's was even created.

My question is, how does one edit Component A without losing Component B, which is a necessary reference to resolve the interference issue.

This seems so basic, and I'm disappointed I don't know or cant figure out the answer.

Thanks,

Hi,

please share a sample file

As the file name implies, this is an oversimplified example. My question: is there a way to edit the sketch of Component A while using Component B (body, sketch, etc) for reference, projections, etc.

Hope that makes sense.

See Attached.

(I removed existing parent/child history dependency and then dragged order in Timeline.)

Thank you for taking the time to demonstrate. I understand the strategy, but cannot figure out how to remove the child / parent dependency to allow the timeline features to be re arranged at the assembly level.

I went through all the component contextual menu's, properties, etc and couldn't see an obvious function.

Where is this done?

Chris

@chrisqx2

Are you referring to your attached "Oversimplified Example", or are you referring to your real model?

I was referring to your comment "I removed existing parent/child history dependency and then dragged order in Timeline."

I was asking how the parent / child dependency of a Component is edited or deleted. I've never seen an option to perform this function. Often, in error, I've created a component nested under another component and figured there was no means to re-define an alternate parent, so always deleted and created a new component.

I appreciate your time, very helpful. While I consider myself quite proficient with the software, its the basic housekeeping intricacies / limitations that I need to study a bit more.

I am not at my Fusion machine at the moment, but Purple lines are Projected lines.

A projected line is a child and has a parent.

The child cannot exist in time before the parent.

You second component had a purple child line - I deleted it with the Delete key on my keyboard.

Now I could drag the second sketch and extrude before the first sketch and extrude.

Of course this was a very simple example. The process is usually more complex on real parts and requires a strong understanding of parent/child relationships. If you use the BORN Technique as much as possible and practical you largely avoid these dependencies.

Ok, now I understand, and that makes complete sense.

I was fixating on a menu function for some reason.

Thanks again.
