Problem selecting just some areas of a subdivided plane
-
I'm not sure if I am understanding your issue... Maybe those lines that form the square are not intersecting your geometry.
Do you explode the frame before "cutting"? maybe is just the cylinder that you are slicing.An image of your problem would give more ideas to others to help you.

The round corners plug-in may do the job for you?

If not try to post some pics of your problem, as sugested by KarinaGM.

Hi folks.
This looks like the perfect candidate for the "Follow me" Tool.
Can you post a file showing what you want ?
Just ideas.

Hi All,
We are trying to do this by cutting with a cylinder.What happens is that we are able to delete the cylinder itself afterwards, but we are always left with a planar piece of window frame, on the same plane as the wall, that we cannot get rid of.
If we then try to remove the closed area covering the window, we cannot select it without selecting a larger area around it, even though it is bounded by a rectangle!
If, instead or deleting a line, we try to select and delete the entire slim rectangle that was once inside the cylinder, we have the same problem of not being able to select this rectangle without selecting the coplanar area of the wall around it.
However, if we make a simple flat rectangular slab, cut a hole through the middle (so it is like a square doughnut with a square hole) and then draw a line across the hole, we can individually select the two rectangles that appear covering the hole and delete them without any difficulty.

Hi. I'll try to make a few suggestions based on the above.
For the shaping of the convex edge, the suggestion above is probably better than the intersection approach you seem to be using. (follow-me tool)
Have you tried click once on the face, so that it alone is highlighted? Or try clicking twice on the surface to highlight the face and edges. Group this then delete. Group and delete is helpful to get rid of things after intersection but leave geometry that shares some edges.
When proceeding to work on detail in your window, it may be best to create a component of it. This way the window is separated from the wall etc. and things you do inside the component to the window will not affect the wall. You might have to recreate the wall hole separately OR you can proceed to learn to make the window component automatically cut the whole in the wall surface. Also you will be able to insert new windows with this component.
Sometimes drawing a diagonal helps somehow when you've done everything right... but usually it indicates something is not co-planar to the other. An aid to modeling is to go to styles and edit the line color so that every line displays the axis color it is on. If you are off-axis with a line it will be black, not colored. That way you can check your drawing as you go (don't try angled walls until you get straight ones--X and Y directions-- figured out in SU).

Thanks Everyone,
I will read up about the "follow me" tool, which I don't understand as yet. Windows as components seem like a good idea too, and thanks for the other suggestions which I will also read more about until I fully understand them - it is knowing what things are called in a new programme that makes it hard to search for the right information, and you have all given us some new vocabulary.
Screen shot of the problem in close-up is attached. The area I cannot select on its own is a complete rectangle and is on one plane. All lines were drawn watching for the indication that they were true to the correct axes.
OK, not attached yet. I will just whip out and read how to attach stuff as I'm not seeing it!

The Follow Me tool has a whole lot of functions I was looking for and hadn't found yet, thanks
The original problem still puzzles me even though we no longer need to solve it! I find that by drawing diagonals and triangles I can delete some areas of that rectangle, but then the remainder works the same way as the first part. If I select it, I still find that I am also selecting the larger rectangle, if I delete a line bounding it, the hole in the wall heals. Bizarre!

You can attach the sketchup file in question and someone will try what you are trying, to see what they find.

Hi everyone and thanks for your suggestions. We eventually found that extending all the lines around the rectangle that we could not delete, until each extended line touched another line, made the rectangle behave "normally" - it was able to be selected and deleted as a single entity. The problem had not arisen because of the rectangle being incomplete, so it was odd, but anyway, there was a solution.

To MaryonSketchup:
From the picture you provided, it looks as if for some reason the edges of that rectangle are not on the same plane as the rest of the flat face. These edges may be "microscopically" separated from that plane, and I do not believe even using Intersect Selected will change that.So apparently you have a faceless rectangle, which may even be slightly twisted. Try drawing a diagonal in the rectangle.
Of course, I may be missing something in the information. You could also upload a copy of your file in much the same way as the image.
Only meant to assist.
