I'm drawing a flat steel part that is 1/4" thick. I want to have an arrow on the sketch that is cut out. curious the best way to do so? thank you
Probably just create an arrow with sketch lines and use that.
Use Sketch Text and the wingdings font:

Just wonderin' if the wingding upsets things.
CNC mill could cut by turning of tool compensation.
Same with laser.
The spline need to convert to segments.
Well, I agree that, if this were to be machined, then the cutouts should be cleaned up (as in no sharp corners). However, as far as the font itself is concerned, the CNC programmers generally take either a Parasolid or a STEP file. Which means that the font itself no longer matters. It just turns it into geometry.

As Dan Pihlaja said, you wouldn't have any problem with the "Arrow" wingding fonts. The "hand" fonts are another story. You'd have to do some editing to get them to work as pockets. If you were just going to engrave them they'd work all right.
You can create the sketch and perform the cut after the initial plate feature, or add the arrow to the same sketch as the plate. Check out the image below and attached file.
The default SW font, Century Gothic, includes arrow characters that you can extrude as sketch text:
As do many other fonts. So, roll your own as Glenn suggested or use the Windows Character Map tool to find one you like:
I would probably draw it once and then save it as a Sketch Block to Design Library.
I don't know about every use case, but I find reliance on fonts hit-or-miss. Options, opinions, and such.
I tried to keep this simple but it didn't work out. I made a 3-line sketch and extruded it as a thin cut. It has two issues to make it not as ideal as I expected.
First issue: Thin feature, 1-sided. I'd need to draw the lines differently, considering their start and end points more carefully. I drew this as its primary line first, starting at intersection and ending at its far point. Then I drew the other two lines beginning similarly at the intersection. This effectively placed a 1-sided thin cut oddly to one side. It could be better, if the two arms were drawn from endpoint to intersection to endpoint, then the intersection attached to the primary line.
Second issue: The notch at its tip. I removed this with a fillet.
I tried to keep it simpler but it isn't.
A simpler way, for me, would be to just offset the lines in the sketch and cap its ends, then cut. No, then again, I tried that and it had issues again with the way the first lines were drawn.
A font would carry more stylistic elements: curves, flats, a taper. This example is intended as a simple linear arrow option.
I usually use font for etching and marking. Cut 0.001" deep so it show on drawing and I can export DXF.
The mill/laser will run along the profile making "double line" letters.
Take more time on the machine but way less time on model and drawing.
As I said above, sketching an arrow is pretty simple...
...and if the corners need to be rounded off, that's what the "Sketch Fillet" tool is for.
I too vote for just sketching and cutting.
However, for thin materials like sheet metal, I recommend something like below to remove acute corners:
And add fillets after:
Assuming there's no concern about fall through.
