Master Model part failure - "The Base Part Has No Solid"

Hi All

I've created a Master model to create the overall shape of a plastic enclosure, then used Split feature to save off front and rear halves. Then added all the necessary detail to the two halves in their individual part files. And made an assembly from those part files.

Then, in one of the halve's part file, I created a new configuration. Clicked the default configuration, Control-C, then Control-V. When I hit Control-Q, all the features turn red. The very first feature (where the part was pulled from the master model) gives the error "The Base Part Has No Solid."

I've attached some pix. Does anyone have any idea what that means, what's caused this, or how to fix it?

Actually, now even the default configuration is doing this, and "Reload" does not solve it

Closed everything, Re-booted SolidWorks. The part comes in ok, with all features intact. Soon as I hit Control-Q, it is destroyed.

Tried this on the rear half, and it still works fine even after creating a new config and hitting Control-Q.

When I "List External References" on the failed first feature, it points back to the master model, and says

Data Status Referenced Entity

Solid Body In context Solid Body of Part A(master)

Feature In context Split 1 of Part A(master)

Very confused and would appreciate any insights.

Correct Answer

Problem solved.

I had locked all references. Then when hitting Control-Q (force regen) the features failed.

When I unlocked all references, hit Control-Q, all the features resolved.

I guess it could see the master model once references were unlocked.

I had locked them, because I put both parts in an assembly, and referenced each other for features in both.

If references were unlocked, and I moved the parts in the assembly (to see the motion between the two), those referenced features would fail.

So had to keep references locked on both parts while working on them.

Although now, 3 months later, I can't recreate the probelem even when locking all references. It's fixed itself somehow.

Thanks Mark, Deepak, Jerry and Jason for your time on this.

Open your master part file and check if you made any changes? Does that open fine?

Can you upload both the files (if possible)

Hi Chris,

I 2nd Jason's question about what SW version you are on. In 2010/2011 versions we enhanced Split Part and Save bodies with the ability to edit the stock feature to correct problems like what you are experiencing.

Using SW2011 x64 Edition SP5.0.

Master part file opens fine, no changes have been made to it.

Further background: I created 6 design concepts, each using this master model method. One was chosen for production. So I used SW Explorer to rename that Master part file and the Split part files to their respective Part Numbers (eg: 857433 and 857434). But inside the Split Feature in the Master part file, it still calls them "Concept 6 front" and "Concept 6 rear". And in the part file, the first feature is still called "Stock-Concept 6 (master)-1 ->"

But, this was done the same for front and rear, and the rear has not got this problem. I have added many more features to front than rear.

Sorry I can't upload these files.

Part opens fine today. Seems as long as I don't hit Control-Q, I can keep working on, and create tooling from these parts.

Chris,

The stock part names are "internally tracked" and not the affected by the master model file name. When they fail, have you tried to edit the stock feature in the derived split part and reassign the bodies correctly?

Hi Mark,

Good to know that the re-naming is not affecting it.

At your suggestion, I tried editing the stock feature in both parts. On the rear half, all is well, and the part rebuilds. On the front half the stock feature is completely blank, and the part fails.

Tried redefining the stock feature: it will let me re-select the master part file, but will not let me select the proper body or populate the "Defining Split Feature" or "Body to Use" fields. It seems the stock feature cannot be repaired?

See attached photos.

Hi Chis,

then this is something, that if you can, please submit to us thru your VAR. I would like our development to take a look at it and determine if this is a bug, or if there is something else going on. If you'd like, I'd be happy to take a look at it personally. you can email me at mark.biasotti@3ds.com - although you should still submit thru your VAR.

Chris,

What happens if you select both bodies when editing the 19-4 Rear Stock Part?

What happens if you open up the master part and edit the Split?

Chris-

Sorry to hear you're still having problems. I have seen instances like you are describing but much less frequently than when split parts first came out.

Maybe about 6 months to a year ago, I spent half a day, trying to recreate the problem in a simplified environment and couldn't. I thought it was tied to the way multilple configurations are handled, but we ended up (like you) just bulling through the situation.

This might be voodoo, but we typically do not save out the splits in the split part feature, but add an addional "save parts" feature for that.

Good luck,

-Jason S.

I've had this problem recently several times. Always precipitated by renaming a solidbody in the master part. My references aren't locked.

It would be great to have a way to resolve this issue and refind the body that the child part has apparently lost. I wouldn't say that "this question has been answered" is exactly a correct label for this thread....

Our company has recently adopted this method for the new product development group. I also ran into this problem today, but locking the references got the part to show back up. When I unlock the references, the first feature fails again and I can't seem to figure out how to fix this issue. Currently this part can not be updated, and I'm tempted to start over.

We are not using this for plastic parts, but for large welded structures. The master model is created first for FEA and design iterations, then the plates are saved out as part files, converted to sheet metal (adds flat pattern configuration), and we also add features (mostly chamfers) required for welding.

Instead of saving parts using the split command, we start with the multi body (master model) part, right-click the solid body and select "Insert into New Part" to create the new one. Then we add features, just like described above, to that new part. After all parts are saved out and modified, we insert those part files into one assembly file to create the weldment drawing (origin to origin mate locates the components). These weldment assemblies average about 40 different parts that are created using this method.

This has worked well so far, but during design iterations it will be difficult to see what is all linked together from the master model part because the parent/child relationship window does not tell you that the multi body part is driving all of those extra part files. I also can't figure out how to edit the failing feature to select a different body from the master model part file.

Does anyone else use this process and have these issues? Any suggestions to improve this process would be greatly appreciated. Please email directly to: justin.zunker@joyglobal.com

Below are some pictures to clarify our situation, we are currently using SW 2012 SP 5.0 and should be upgrading to 2014 around August.

I am having this problem as well. I just deleted a hole and added a revolve cut to a body and now i have the same error. I know which body to tell SolidWorks to use but there seems to be know way to do this edit.

Has there been any changes to this problem in 3 years? Any possible solutions yet?
