Is there a way to trim circular center marks at the red lines shown in the drawing.
You can generally grab and drag the blue square at the ends of center marks to adjust the length as desired. Have you tried that?
That was a snippet, it's actually an entire circle like below. So no ends.
Is that a line that was sketched in the Drawing view? If yes, delete it and insert an arc instead, or use the Split Entities tool to break it and delete the unneeded portion. Or delete it and insert a Centerline, choosing the two radius edges to place it.
The large radius is the center line that is added when you click "Circular lines" box in the center lines options. Everything you see there except the two outermost lines are center lines in that function. Does not look like you can split center lines.
I'd just delete that and insert a standard Centerline instead of the Center Mark. It's usually used for straight lines, but it works just as well for arcs. Then you can control the length by dragging the ends as I said above.
Why not use a Radius from one end to the other aligned to the holes or concentric to the Radius of your part..
I know I can do that but it seems like there should be a way to trim the center lines. You can limit the size of the center marks, was wondering if you could split or control the circular marks as well.
You can sketch a box around the view and then do a Crop View and it will trim the circular centerline.
Unless I'm misunderstanding something, you should actually be able to select just that segment of the center mark's "circular line" and press delete. Just as you can delete individual center marks from a set, you can delete connection lines and arcs as well. This wouldn't trim it exactly as you asked, but it would get rid of the massive circle.
This particular behavior is alarming. Having to fake in a partial center line is just another example of the hoakieness of the Solidworks program. How can this program have so many releases and not have this "feature" up to date with the norms of CAD software society?
I think this is the frustration and or challenge with just about any type of software out there. The "Challenge" is to try and figure out whether you don't know how to use the software or whether the software won't do what you need/want it to do. The "Frustration" is finding out that indeed the software won't do what you think it should do. I can't remember a piece of software I have not run into this with and SW is certainly no exception.
What I do find odd about SW however is that in many cases "New" things are added over and over again without fixing relatively simple things.
I have to correct myself. Upon further review, you can produce a center line just like the OP would like. Just insert the center mark with the "Circular Lines" checkbox not selected in the "Manual Insert Options" section of the dialog box. In the "Display Attributes" section of the dialog box, make sure the "Use document defaults" check box is unchecked, but the "Extended Lines" check box needs to be checked. Then for some reason, on my system, I cannot move any of the little blue boxes at this time, so just hit the green checkmark on the dialog box. Then, click on the centerline so that the little blue boxes appear again. You should be able to drag those boxes around to whatever position you like around the center line circle. Don't worry however not all is well here as I cynically report. If you would like to have a partial "Base Center Mark" that would have a truncated leg of the centermark, you would need to put that in separately.
