Replace Base Component in derived parts

[francesco_rossato]

Hello,

I have an issue with the new feature in 2022.1 version of Inventor, regarding the possibility to replace the base component in a derived part. Here is an image from the "What's new" web page:

At first, we were so happy about that, beacause we needed that so much, and apparently everything worked well.

Now, we realized that this new feature doesn't work, in particular when the base component is a sketch! In fact, Inventor replace the base component, but the sketch into the derived part remains the old one. 

It is clear that this issue is penalizing, mainly because we have to create different features starting from these derived sketches. If we don't have the possibility to replace the base component, we must delete all the features, derive once again choosing the new sketch, and re-create all the features we made.

Anyone has experienced this problem? Is there a solution for that? If needed, I can post an example to better explain.

Thank you!!

Francesco

Hi! I took a quick look at the files and the workflow. I believe this is a bug. Here are my findings.

The old source file and the new source file have the same Document ID. From Inventor's perspective, the two are interchangeable. The simplest test is to compare the workflow with the traditional hack: Resolve to a different source file. For example, in this case, instead of using Replace Base Component command, just rename the original source file and force Inventor resolve to the new source. You will see the derived sketches are all intact. This means Replace Base Component is doing something wrong. It should just work regardless. I will work with Shiva and the project team to understand the behavior better. Hopefully we can fix the issue soon.

Many thanks!

Thank you @johnsonshiue .

I have created a defect to track this and assigned it to the appropriate team. We will take a look and give you an update. Thank you for the detailed steps.

Hi @CPEng16, when replace base component, we will decide if include a node or not by checking its visibility. If a node is not visible, then it will not be included. It's the same behavior as that when derive a component from scratch by default. When derive from a part, if a sketch in that part is not visible, we can see that sketch will be excluded by default in derive dialog. 

In your workflow, the sketches in that base part are not visible. So they will not be included when replace base component. Then the original sketch in that derived part will be isolated as its source is not included. That means its reference will be lost. So if we want to keep those references, we need to make those sketches visible in the new base component.

Hi @sysh 

I can confirm that this works. Thank you for the clarification.
