How to cut surface marked in black. It is a surface stiffener on a surface. What is the best method to do it and how ? Is it fine if i make a sketch and extrude it and use trim or split tool to cut it . But after cutting when i delete sketch which i used to cut surface, stiffener part again show up. Can i cut this part without unnecessary sketches.
I may be wrong but as far as I know you have to retain any sketches you use to either extrude or cut parts.
Delete the sketch, lose the feature.
You need to trim surfaces, you can use the Cut Extrude for surfaces.
Dilraj,
Edit the original extrude cut and select Direction 2 and distance through all.
Should accomplish what you are trying.

Surface? or Solid?
Attach your *.sldprt file here and end all doubt.
A few things:
1) If you reorder your tree, then you should be able to use your cutout that is already there to cut the stiffener. Just put the stiffener in before the cuts....then make sure that the cuts go through the stiffener as well.
2) Solidworks uses sketching as its main driver. There are ways to get around it, but you need sketches. So if you can't do #1 (which I don't why you couldn't) then you will need a sketch to cut that.
The only work around I can think to use is to use the sketch that defines the hole cutouts to also trim your rib surfaces as shown in the image below. This will remove redundant sketches, however a surface trim needs to have a defined sketch telling it what to trim and what to trim it with.
You could quit focusing on the how you get to the end result...and be happy with the end result.

I am not sure that I understand what you mean here.
To me it sounds like the op can get the end result model he wants, but is trying to do it without some sketches to clutter up his tree.
Ahh, now I understand what you are saying. I thought you were saying to not even study the why, just the how.
(off topic).. but, that's like having only "1" beer.
never only 1....is it time yet?
It's 5:00 Somewhere

As Tony mentioned, Whenever you use a sketch for a feature, the feature will be deleted when you delete its sketch
the other way you can do is using "delete face"
And we're back to the original reply!
I did catch that.
I've never used Delete Face. Since his "stiffener" runs all the way across the part wouldn't he still need to define the section he wants to remove? Sorry to show my ignorance, I just want to learn.
I just created a quick model and used "delete face" feature without adding extra sketch
EDIT: or you can use shared sketch as Kevin mentioned is his reply

Thanks for the explanation Christian. You define the face to delete by utilizing the original sketch to split the stiffener.
I thought it would be something like that.
Thanks again!
Thank You
Hello,
Assuming the rounded rectangular openings are their sketch, you can try a Cut-Extrude using a derived sketch.
Expand the tree and select the sketch used to make the openings
Press (& hold) the Ctrl key and click the face shown then start the Cut-Extrude command.
Add dimensions to position the sketch (w/dim values set to zero).
Exit & save the sketch and be sure the cut is headed in the required direction.
I hope this helps,
Kevin C.
BTW: As requested above, assuming you're permitted to upload the part, the replies would be completed models instead of textual suppositions.
