Welcome to the forum. It's been a while since I used that version, but when you make the extruded boss or cut you should be able to choose which region of the sketch to use for the feature in the "Selected Contours" section of the PropertyManager (near the bottom). I think it was there that far back but I'm not sure.
Attach the file here that exhibits this behavior.
It is also possible to reuse the same sketch (or parts from it) in more than 1 feature (extrude/cut/etc).
Welcome to SolidWorks forums Nathan.
As Glenn and Jeff suggested, you can use the selected contours option to select the area/entities for the features from a multi contour sketch.
Attached a simple video to show that

The problem is, is that once I extrude/cut one part of the sketch, the rest of the sketches become unusable, and they appear with blue, dotted lines. I cannot use the others to do anything, except edit their sketches which is not what I want to do.
You can use one sketch for more than one feature. After using it the first time it will be absorbed by the feature in the tree, but you can expand the feature, select the sketch, then select the next feature while the sketch is still highlighted.
Ah, yes. I see now. That is quite awkward. It never did this before so I was confused. Thank you very much for your help.
I'm glad I could help. In later versions of SW you can choose to have sketches not absorbed by features but I'm pretty sure that wasn't available in your version.
If you check the video I've posted above you can see the steps of using the same sketch in multi features.

Hello, I'm using Solidworks 2009-2010 and for some strange reason, recently, when I have gone to sketch two ellipses or two circles that have the same centrepoint, it classifies the two separate sketches as one individual sketch. I don't want this, because it won't let me to extrude one and extrude cut the other. So I want to know how to separate these two sketches into their individual parts, as I have not found a way to do it yet. Thank you.
one sketch can only do one thing as a rule, extruded boss or cut, from the get go.
so if you are saying you are making a dougnut sketch and you want to extrude to outer as a boss and the inner as a cut you would have to use the contour select tool at the bottom of the extrude property manager to the left, select the outer circle then extrude the exit.
Now click the + sign in front of the extrude feature, show the sketch select the sketch and now hit the extruded cut feature then click inside the small circle and then the cut property comes up and you can do a blind cut.
or the simplest is just make to sketches for each feature...?
Select sketch contours and model edges, and apply features to them. This allows you to use a partial sketch to create features.A tooltip appears when you cannot select a contour because:
- The part has too many edges.
- Edges are created on offset planes.
- Edges are chamfered.
- Edges are filleted.
When creating lofts with 3D sketch contours as opposed to individual sketches, you can select one or more contours.
- When reusing a sketch, you can select only on the original face. If, for example, part of the face has been extruded, the tool does not recognize the new face.
- You can select contours only on the face with the sketch. If, for example, the face with the sketch is cut by a solid object (as shown below), the tool can select the part of the face still visible but does not recognize the solid object.
- In an active sketch, select a feature to apply the selected contours. For example, click one of the following to display the appropriate PropertyManager:
- In the graphics area, use the pointer to select a contour for Selected Contours.
The contour can include model edges.
To select multiple contours, hold down Ctrl.
- Click to apply to the selected contours.
