I'm trying to scale a ship (KVLCC2) by a ratio of 10. However, when I do this part of the ship gets lost. I've tried to knit all of the faces together to avoid this but it doesn't seem to help.
Can someone help with this?
Surfaces there caused problems prohibiting you from creating a solid. After some tinkering I was able to make a solid and it scales with no issues.
What did you do to make a solid? Is it just a case of removing a few features of the model?
As you can see in the feature tree in the attached file, all I did was remove the troublesome surfaces and replace them with lofted ones (the ones that generate the least problems based on my experience). After that I was able to knit all surfaces into a solid using "Knit surfaces" feature.
Thank you for explaining, it makes more sense now! Unfortunately I can't open your file as I have an older version of Solidworks (2019) - but I will have a go at it!
I've tried to delete a few features and replaced with a surface loft, however I'm still getting the same problem. Would you mind looking at my feature again?
Delete those two faces:
Use lofted surface connecting those two edges:
Use surface fill to get the little triangle shaped surface:
Knit it all together to get a solid:
I hope that explains it well enough.
-Converted your file into parasolid file to reduce the length of the tree.-Converted the part into surface.-Scale it by 10 times.-Surface fill the opening (small one) created by surface conversion.-Surface knit to create a solid.
File is in SWX 2019v
Thank you! This works well on my machine.
I'm also trying to use a sensor to find the waterline of the ship however when I hollow it by unticking "Create solid" on the knit surfaces feature it greys out the mass properties as so. Do you know why this is?
Thanks for all you help!
wich mass properties do you expect to get from a part without a volume? It's just a surface body wich is not filled at all. It can be opened or closed - doesn't matter for SWX...
I want to get the mass properties of the hollow ship, not the solid ship. I thought I would be able to get this for the surface body.
As you can see, this won't work. You / SWX needs a solid body.
And what would be the difference? As long, as your surface has no thickness, it'll be the same...
Volume of the surface body is zero for SWX, even though you can see it from your eye.
