[kanishk]

here i have to cover up the top using the highlighted curves.

I started off by making a mesh of curves.

But the boundary blend tool does not work for any of the logical selections.
Any suggestions?

Instead of using boundary blend,try the feature Conic
Surface and N-Sided patch and simply select the curves one
by one.You will get the desired geometry.
Make sure that all the curves are connected to each other.
No need of creating a mesh of curves.

This command is available under advanced menu options.
#Insert>Advanced>Conic Surface and N-Sided Patch.
Select N-sided option and continue.

Hi Jacek,
That looks like a great resource for surfacing tutorials.
How do I access the other tutorials on there?

I've never had much luck with n-sided patches, so I gave this a try. Works well, but all by itself it doesn't produce the 'dome' he shows in his image, in fact it's actually concave.

Adding in the cross curves and using an N-sided patch on 1/4 of it is better, but the tangency creates an odd bump along the curved side.

I split it in 8ths and created it with a boundary plend and that is better, but now slightly faceted. It's also a rather large file for some reason.

I've attached a zip file of the 3 parts in WF5. I had to suppress some features to get the file size down.

Same.


The tangencies work but patch to patch has a little hump. I am not sure if it is because of my splines...

N-sides are a little hard to work with, especially with the old interface limitations.

ok, just to announce a little info - my page has been updated recently, and all tutorials should be available directly from proe-warsztat.com now.
