Re: How to delete all the invalid geometry in a sketch?
You can select multiple sketch elements with a click and drag box. Will that help?

Re: How to delete all the invalid geometry in a sketch?
That doesn't help much in this case, unfortunately. The invalid geometries are tiny sketch segments scattered randomly throughout the sketch. Many are too small to be seen unless I am zoomed in pretty far, so I am just having trouble finding all of them and getting rid of the error!

You should still be able to use a click and drag box selection. Do that over the whole sketch area, then hold down Ctrl and click on the sketch elements you want to keep to de-select them. Then hit the Delete key on your keyboard. That should delete all elements you didn't de-select, even if they're very small.

They should get selected with a drag box even if you cannot see them.
Also, if you can make a block from the good entities, it is easy to select all and then unselect the block.

Re: How to delete all the invalid geometry in a sketch?
Like Glen said - click and drag a rectangle to select is a good way - note that a left to right drag only selects what is entirely inside the box (blue) and a right to left drag will select anything that crosses the box (green) - these methods work with multi selecting (holding the ctrl key)
Also, if your "good" entities are few and easily selectable, you can grab them and create a block froom them. Then select everything (ctrl-A) and ctrl click the block to unselect end then delete...
There may also be an "invert selection" on the RMB menu.
Hope that helps a bit.

Re: How to delete all the invalid geometry in a sketch?
Say there are 10,000 elements (such as a line or circle) in a sketch, and 800 of them are invalid. Using the method described, I would have to select all then deselect 9,200 elements. Is there a better way than that? Perhaps a command that eliminates the invalid elements automatically? Perhaps a method that highlights those elements so I can select them individually (not prefered, but better than selecting the 9,200).

Tyler,
Depending on your situation, there may be a better way to walk around this shortcoming. But, if you have everything modeled and you are just trying to solve it (but the model isn't 100% correct, so it refuses to solve it) this may be a viable solution:
- You have a sketch you wish to extrude from; you select those lines/items of relevance and extrude them to generate a 3d part/body. No problems with the extrusion. However, parts of the drawing sketch itself (parts we co not even care about) are flagging errors and Solidworks refuses to ignore them.
- Before you make a simulation model (or get too crazy in your assembly); address these errors right away to make your life easier. Assuming we are already in an assembly and we have parts with invalid 'sketch' components being flagged, we can [FILE] > [SAVE AS] the entire assembly into a [part] file. this will 'flatten' the whole assembly into a part. This will 'delete'/'forget' sketch data.
- open the new 'part file' and all of the assembly-subcomponents are all 'bodies'. If everything is okay, then you can right-click on your solid-bodies; and [save bodies] ; from here you can give names to those solid bodies and save them back into an assembly file (that is [save as assembly] check box to be designated.
- Specify a name for your new assembly from solid bodies. and Save
- Open up this new assembly, and ti should look the same as you started, only No sketch information and no errors.
Yes, not the best if you plan on modifying the sketch for future revisions, but maybe you don't have an interest in revising that sketch of yours.
Let me know if that helps.

Can you select one of the good segments and do a tangency or loop selection and then start a new sketch?

import the dwg file.
leave that sketch there for ref.
start a new sketch convert entireties, then trim them to meat up and then you do not have to deal with the little lines.

Re: How to delete all the invalid geometry in a sketch?
It happened with negligently drafted ACAD files.
To fix file you have to deal with each error individually.
Try to apply SW Repair Sketch Tools
Usually SW is able to recognize most of issues:
