BUG? Components spontaneously turning into Base Features since latest update.

warrior_nerd — Sun, 06 Jun 2021 21:06:59 GMT

Since the latest update, I am modelling as normal. Insert component, make a sketch, make feature(s).

Insert another component etc.

At some point I will open the file and one of the parts is now a Base Feature.

I NEVER turned it into a base feature myself and the Capture Design History is definitely ON.

It has happened to two parts today.

I have been modelling for a LONG time with Fusion without this happening, so I'm pretty sure it isn't user error.

Can you attach one of the components that this happened in?

It is a Component for machining and a Component as the stock for machining.

One is inside the other.

I imported the Solidworks part as a component.

Insert new component, activated it, made a sketch and extruded it.

Activated main project and added the joint. Changed opacity of stock to 50%.

Then I went to the Manufacturing space and made all the setups.

IRL, I cut the stock, measured it, and went back into the model to adjust the stock dimensions to match the actual stock. That's when I found that the Stock was now a Base Feature...

Here is the shared link:

If there is a better way to attach Fusion files, please let me know.

Thanks.

I stepped through your steps from the original model but I did not experience the shift to a direct model, I will keep looking at it. By the way, sharing a model, as you did, works fine except it is dynamic. You are still working on it and saving so the shared model is not at the same state where you experienced the issue. A much better way to share a model is to go to the File menu, choose Export and save the model to your hard drive. Then use the Attachment section of a forum post to attach it. This way it is static and shows your model at the exact time of the issue.

I am curious why you create a "stock" component in the design environment instead of just defining your stock in the manufacturing environment? Maybe you want it on the parts list of the drawing is one guess.

I create a stock model because:

1. It is easier to define and change.

2. Sometimes I have to add dovetails or other features for a mini vise to grab it.

I'll try and pay attention to when a Component becomes a base feature.

I've been using Fusion for a couple of years and have been doing 3D modeling for over 27 years, so I'm solid with workflow and process.

This happened 2 out of 2 times since the update, and never happened before. In fact, I didn't even know that Base Features existed until I saw one in my model (I have virtually no need of ever making one).
