Hi Pilou,

You made me laugh with your first picture it looks like an acne cream advertisement showing before and after :)

Hopefully the original trim curves weren't deleted.

In fact they don't exist, it's my problem to refound it!

Hi Frenchy,
Yes, extracted all those surrounding edges and then ran blend on the open areas, so I could retrim the boundry.....

But yeah, if you had a file with "250 little open areas" it may take awhile.... I guess you are asking about something like an "autoclose"?

If any of that is unclear I'll make a video.

<< I guess you are asking about something like an "autoclose"?

yes absolutly! :)

A little video is always wellcome!

I am interested of your drawing lines / curves surrounding edges for the numerous (or not) closing holes on the sides!

Hey Frenchy,
Here's a short video using a couple scripts:



I used points to mark the start of the openings so I knew where to blend. It could help if there were "many openings", but at the same time, selecting that boundry would be tedious, if there were many of the little openings. Not sure of any way to automate that. I would guess there really isnt any need for the boundry to be "Not a square", so I would just use the rectangle tool and go from corner to corner on the surface and use that to trim. Just running the "untrim the outer edges" script only.

Anyway.......

Thx for the video!

Cool trick to write some words on the screen for help to see the actions to make!

Any reason for make an extrude and not directly a simple Trim with the "rectangle"?

And yes an automatic close a set of lines will be useful ! (Merge function don't work in this case :(

""""""""""""Any reason for make an extrude and not directly a simple Trim with the "rectangle"?"""""""""""

I had some issues with using the curve. I probably could have "flattened" it and had it work. It's just a method I use when I have problems with the trim curve because it seems to be a more "direct trim" as opposed to the "projected" one. Maybe Michael can comment on this. Like "having the trim curve be non-planar made it a different calc or something.

""""""""" It's just a method I use when I have problems with the trim"""""""""""""

..i do the same..
i think cutting surface must penetrate into other surface,when last one is complex
i suppose that trim using just a curve project a lot of points,and if the target is ondulated or complicated,tool not project enough points to cover all the wavy:so trim fails.
(this is just my deduction,forgive me if is not correct)

thanks Burr for your tuts,i learned few fundamental tricks in the past
just don't know why you don't speak also...it's your leanguage!!! (i must do lot of effort to speak in English when i record my modeling sessions...damn...)

Hi Burr, yeah a trim curve that is non-planar goes through a much different process than a planar one, it tries to get the curve onto the surface by a process of pulling it down along the surface normals, but that process in the geometry library only works very well currently if the curve is really pretty close to the surface already. If it's a fair distance away it tends to make squiggles in the curve. I've been planning for quite a while to overhaul that particular "pull down 3D curve to surface" mechanism.

I'll try to remember to speak in them. I guess it can help some with alot of the little stuff.....
