Punching holes

[Boriqua]

Hey Everyone

I have a model that is tapered in the middle and hollow on the inside. Kind of like the neck of vase. I want to punch holes through the skin so light can spill in and out of this shape but when I try to subtract a solid from this vase shape it punches through no problem but turns my vase shape into a cylinder? Can I do what I am trying or have I bumped the cieling. Thank you for any help

What type of object is your original vase object?

[Jonathan Pickup]

I can do this.

But have you also considered that you can punch holes with a transpearancy map rather than modelling?

I made a shape did a sweep and created my swans vase neck shape.

Archoncad ... I bow to your skills

What is a transparancy map, how do I use it and is it impossible to do it the way I am trying. That is COOL! I am actually designing a tower for a childrens museum and I want colored transparant apertures.

Are you expecting a faceted surface and getting a smooth one, or is your swan's neck disappearing, replaced by a simple cylinder?

I just want to punch homes through the skin of this or something very much like it.

Yes, a Texture with transparency works:

Alex,

I just had a go at a shape like yours, and it worked for me.

Can you write out step by step what you did.

Also, can you post the shape you swept.

That is a link to the file. Basically I created a cylinder that I then used to pierce the vase and hit subtracte solid. But then for whatever reason the vase turns into a cylinder?

Can someone tell me more about transparancy textures. That looks like a handy tool to have in my bag of tricks.

Boriqua, I tried it with your file and encountered the same problem. It seems to me that the problem comes from your initial sweep shape being made up of two unclosed polygons. What happens is the polygons closes to complete the solid shape resulting in your cylinder. If you edit your 2D shapes so that they will compose into a single polygon the solid subtraction will works fine.
