Modelling advice needed

Hi MOIers,

I attached a file and a screenshot of a modelling challenge I am currently facing.

Version a1 to the left shows a shape where the profile is gently fading out vertically,

What I want to achieve is depicted on the right (a2) - the same profile fading out gently
but the fade out should end in an arc and then progressing linearally.

Difficult to explain but I hope you got it.

Thankful for tips ! Tom

Hi Tom, it's difficult to impose a good quality arc shape at the end using all vertical planar stations with Loft.

You might try building the arc structure first as a thin strip using Sweep, then do a blend between that strip and a central piece kind of similar as what's shown here: http://moi3d.com/forum/index.php?webtag=MOI&msg=7516.11 notice there how there's some open space between the pieces that is filled in with Blend.

Let me know if that doesn't make sense.

Hi Michael, I am always amazed by your support, thenk you for replying so fast.

<<Hi Tom, it's difficult to impose a good quality arc shape at the end using all vertical planar stations with Loft.>>

I used Network. In the attachment the original file which is more complicated as it is curved. Thats why i had attached a simplified version which is the one we are talking about.

I have tried to sweep and blend and have gone through the example of Chip without success. I will have a closer look at it again.

Hi Tom, the curved shape adds quite a bit of complexity, is it possible to do a flat version and then produce the curved one by using Flow to deform it?

The method I was thinking of was to maybe focus on the arc end shape first by building something like this:



The idea there is to focus on the end shape by itself near the tip there, also you could construct this out a wide area and maybe trim off excess later. Then the center part gets surfaced separately with some space around it and a Construct > Blend is used to connect them together.

This is a lot easier to control with a flat shape though which is what I had thought you were doing...

Another possibility might be to make a shape that extended and dipped downwards past the outer surface and then got trimmed off something like this:

Hi Tom,
is this the type of result you want.
I networked the Bulge without the fillet and then tried various
fillets and blend solutions.
Hope it helps.

Here is a method of using blend. Adjusting the creation surfaces will control the bulge position.
