Help on generating 3D Sink drawings?

[tenghuii]

Hi, actually i'm still new to drawing 3D objects,
so, hope all the experts here can give me a hand please,

i've been trying for months on drawing of a kitchen sink, still encountering difficulties on drawing the bowl part, due to its irregular shape,
been trying to loft it through circles, but not so ideal cause the shape doesn't look smooth enough,
been trying to sweep the surface as well, but failed.

please, urgently need advices...
..mental broke..

any suggestions???

Loft and sweep? That doesn't sound like plain vanilla AutoCAD. What program/version are you using? Or is this a case of terminology?

I build sink bowls using and combination of faces and arcs that can be converted to meshes. It is just easier to automate. -David

Sounds like Inventor.

I'll move the topic.

Post an orthographic or photo and I'll knock one up. Ice climbign tomorrow and MTB on sunday but will check back over the weekend.

However, this free site has pictures.

There is also some free models. Most of the files are cheap <$20.

quick sink, took less than 10 mins to model
No need to loft/sweep
I just extruded a rectangle then fillet all corners big fillets at the bottom then shell it and add a drain hole and the drain board and hole for a tap. job done.

Deelay,

Nice job! For 1s and 2s, these programs are great. I just don't if you make for repetative actions with various sizes, shapes and locations. -David

I don't quite understand your question David?

[David Bethel]

Wow, can I butcher the english language on a keyboard or what?

What I meant was that for single models, 3D programs beat vanilla AutoCAD in speed and versatility. I don't think that they can do the repetative jobs as well. -David


PS I've been trying out FireFox to access the forum. I think I will go back to Mozilla 'cause of the spell checker.

But IV can create assemblies etc update part sizes via parametric data etc.

Do multiple arrays, mirrors of parts and features.
