Solidworks surface trimming

Solidworks surface trimming

Solidworks surface trimming

(OP)
I am trying to trim a surface using a sketch. It works, but the trim projects through all surfaces, not just the one I wish to modify - there is no option to set a direction/depth as in 'cut' with solids.

Is there another way? I have tried creating an extruded surface from the sketch, then a combination of trim and delete surface, but it will not let me delete all parts of the trim surface and looks an untidy solution.

Thank you for your help.

RE: Solidworks surface trimming

I normally use a surface for this sort of thing because of the additional control.  When modeling with surfaces, things do get a tad sloppy, since you can get a zillion "construction" surfaces happening along the way.  But instead of deleting them, you can simply hide them.  (I often reuse them later anyway.)

So by my experience, this is just a messy process.  To reduce confusion, I name my surfaces, and when a given feature is completed I stuff all the supporting geometry into a folder which is labeled according to the feature I just created (I've had parts with hundreds of features stacked up before).

If you need to delete part of what is recognized as a surface by SolidWorks, use the Delete Face tool instead of selecting a surface and hitting the Delete key--that way you'll have a parametric record of the face deletion, and you can select a single face of a surface for deletion.  (This is useful for cutting a hole in a surface with a split line, for instance.)
