Here is one solution.

Using the surface fillet tool, create the orange fillets first, then the yellow.

HI,

Thank u very much for u r reply.

I have few doubts in surface filleting.

1. Why you  used Chord in construction type and Tangent length in Chord type option instead of using radius
2. Hope u have untrimmed all surfaces and did filleting, is that is the procedure we should follow for filleting.
3. Generally i used to fillet in trimmed surface.  (I m learning Alias on my own and ofcourse from people like u)
4. Pls tell me is there any proper way to do fillet or any procedure in proffesional filleting.

Thanks once again

Hey Karthick,

1. Using chord vs radius, in a situation where the angle between the two surfaces remain the same, will make no difference. It will make a difference when the angle of the 2 surfaces changes from one end to the other, for instance. The tangent lines for the chord version will remain more parallel, the radius versions tangent lines will taper together as the angle between the 2 surfaces increases. So i could have used either in this case.

2. I originally used your surfaces as they were but after making the fillets, I ended up untrimming your surfaces and deleting many of the extra trim curves and then retrimming. So the fillets ran long and I trimmed them back to your surfaces.

3. Yes, using the fillet on trimmed surfaces is usually best but often times things get untrimmed and, because of the history making adjustments, the fillets rebuild themselves to the untrimmed surfaces.

4. Everything works best if you can figure out the correct order in which to do things, but there will often be situations where you need to do one thing and then go back to do something else. So often the history can work against you in these situations. Sometimes there is no way to avoid these issues.

Good luck, and let me know if you want more detail on the differences between the fillet types, or anything else.

Hi Karthic

I modelled the fillet solution for you & then saw that John had beaten me to it!

Really nice modelling John!

All I want to add is that when learning to become a good Alias modeller, it is important to realize the need to keep your modelling clean.

So as a bit of general advice to all the students reading this, whenever you try to intersect surfs. or create a  fillet and it fails on you, you must backtrack and do some house keeping.

Failed procedures often create a build up of COS, which add massively to the computation that Alias must perform in effecting a task and at times render it impossible.

Duplicated, spurious or broken COS are a no no! You must delete them if you get into this habit your work flow and confidence will grow.

Hi John,

Thanks for u r continous support.

I tried out your filleting procedure and it worked perfectly.

Thanks once again for u r reply.
