"An empty box has no limits"

Hi there,

got this message when I try to subtract an imported solid from my main body.

Any ideas? Thanks a lot...

What do you want? Philosphy from your CAD System!

That was easy Jim...

...but true. Steli, you can understand that this is not much information. Where do you get the solid from? Is it a dumb solid? are you sure about its integrity - get a JOIN of the complete surface, then explode those surfaces into pieces then JOIN again and turn into solid...

What about the topology? can you post picture ?

does it work with another imported solid? Try to make it in another file...

Sorry, couldn't help it.

I've seen this message, but I can't rememer when. It seems to me it was related to subtraction of a solid that results in no geometry left, but I could be mistaken - it's been quite a while.

Sorry guys, I was indeed very laconic. Actually it happened to one of my colleagues.

We have to go now, tomorrow I´ll give you more details.

Hi again,

This is our scenario: when working in a mold, we try to remove the "drill hole" (MTD license) of a Side Slider from the main body of the Core Plate. The removed body is built in the Slider part, using simple features (pad, drafts, fillets) and here we have no problem (disassemble and join back with no problems). As soon as we copy-with-link it in the Plate part, it somehow gets into trouble... Here the disassemble-join does not work (another "phylosophical" message: "GetLow on an empty CATSurLimits has no mean") and any operation with this body is not possible (here we get the title message trying to remove it from the main body). We ran a CATDUA clean on both parts, but still no luck... I feel it´s some sort of product-related problem, but unfortunately we got the product structure from the customer and we´re not allowed to change anything...

The 2 parts belong to 2 different subproducts found on the same level in their parent product.

Regards,
Steli

How are you copying the geometry in to your part? Are you using Design In Context (Import Links)? Or are you using Cut/Copy/Paste (CCP) links?

Have you tried using the "Create CATPart from Product" tool and then tried the subtract? Just to see if it works in the first place? Then you can mess around with trying to get the links working.

Usually we do Copy - Paste-with-link in the context of the product (not between 2 separately opened parts).

For the moment we just got this project "on hold", so we´ll probably try to mess with it later. I feel we need at least a "clean" of the whole thing (quite large assembly), and this will be quite time-consuming... we´ll probably schedule it over the night sometime.

Thanks for the suggestions, we welcome any news...

Regards,
Steli
