Sketch fillet doesn't select
thomas_holford
Member Posts: 36 ✭✭
I'm trying to put a rounded corner on a rectangular extrude using the Sketch fillet operation in sketch. Contrary to what the pop-up help message says, the sketch fillet operation does not recognize or select the corner of my sketch.
Is there some trick to getting the function to select within sketch?

That model opens fine. You didn't mention which Part Studio, and which part, the problem was with, but I gather it must be the Side Board?
If so, your issue is that the Extrude-Add operation which creates the body depends on a sketch (Sketch 1) which lies at right angles to the desired fillets. This means sketch fillets are not a very useful option, because there is no way to incorporate them in the sketch.
The edge fillet you have used is your only option, unless you rethink the orientation of the sketch of origin. (Hardly worth it, unless you judge the sideboard may require in future to have a more intricate shape, rather than a simple rectangle with fillets.)
There is one (not very practical, but perhaps for some situations, considering it now would be instructive) other option: If you had your heart set on sketch fillets, but wanted to retain the current sketch 1 (say hypothetically you wanted to fillet those corners, as well):
You could make a complete new empty sketch at the required new orientation, "Use/Project" the rectangular outline, fillet the corners using sketch fillets, then use "Extrude/Intersect" rather than "Extrude/Add" (the default) or "Extrude/Remove" (which you used for the holes). You can think of this as using a cookie cutter (like Extrude/Remove), but throwing away the cookie and keeping the 'frame'
Getting back to the perfectly serviceable model you currently have: You could reduce the number of fillet features to one, by picking both the edges to fillet in one feature. (This can even be done to more than one part at a time, provided the fillet radius is the same in all cases)

You might have to reload your browser tab. If that doesn't work, try holding Shift down while reloading it.0

Hi @thomas_holford if you already have a solid body (Extruded) you have to use the fillet feature in Parts Studio not in sketch, this one is to fillet sketches 2D only.

or you can add a fillet to the sketch after creating the Extruded solid .... but to do this, you have to "Edit Sketch" for the sketch the extrude is based on.0

Well, yes. That is what I eventually figured out.
So, in other words, the Sketch fillet function ISN'T working.-1 -
Works OK for me. I can select either the node or two lines as expected.0

I'm using Chrome on Windows. I also use a Chromebook, and I'll check and see if anything is different.nav said:@thomas_holford what browser are you using ?0 -
@thomas_holford You can also check if your Java version is updated fully.0

Assuming you were replying to me, in the first sentence:thomas_holford said:Well, yes. That is what I eventually figured out.

It isn't working outside of Sketches.
Nor will it ever do so: It's not intended to.0 -
The quote function for this forum seems to me screwed up. So, I'm commenting on brucebartlett:
I have figured out that my sketch didn't contain any lines. The rectangle I was trying to select was the face of the extrude which defined the sketch plane. But it is not included as part of the sketch.
By drawing a rectangle that traced the outline of the extrude, I was able to select two lines that defined a corner for the Sketch fillet operation.
HOWEVER: When I closed the sketch, the corner of the extrude was retained and the body of the extrude was deleted. This is probably because the extrude function which was tied to the sketch was for a remove operation to create holes.0 -
My trick for using the quote function without getting stranded in cyperspace is to type in some text as a 'placeholder' below the quoted message before I do anything fancy, even just inserting a carriage return ("Enter") and certainly before using the Delete key.
If you don't take this precaution and you lose that precious white space after the quote, it seems to requires a PhD in computer science, majoring in html, to recover any semblance of a post.0 -
In Onshape terms (as in most other modellers) the term "sketch" is reserved for linework created by the user rather than the application, listed in the Feature list as a "Sketch"
There should be a sketch further up the tree driving the Extrude:Add which created your solid body:

The project name is "Ramp 6 x 48". Is this enough to find the document?
In any case, the URL is:

Quick lesson:andrew_troup said:My trick for using the quote function without getting stranded in cyperspace is to type in some text as a 'placeholder' below the quoted message before I do anything fancy, even just inserting a carriage return ("Enter") and certainly before using the Delete key.
If you don't take this precaution and you lose that precious white space after the quote, it seems to requires a PhD in computer science, majoring in html, to recover any semblance of a post.
Open html editor from button < / >
Look for "<blockquote class="Quote">" - that is where quote begins.
Quote ends to "</blockquote>". You can add plain text before / after that block directly to html editor (just add few letters as placeholder) and then turn html editor off and you have again white space above/below quote where you can write your post.
