magwea Posted February 5, 2009 Posted February 5, 2009 I've attached a drawing with my problem in which I can't figure out the construction for finding the fillet between a point (the arrowed corner on the bottom top left rectangle) and on a tangent of a half circle (also with an arrow). Since the radius is unimportant for this drawing, and is unknown anyway, i know there is an infinite number of fillet radius that i could use but i am finding it hard to find one that doesn't cut into the vertical line of the rectangle which is the only other requirement. Can anyone enlighten my? tanget through a point.dwg Quote
Tiger Posted February 5, 2009 Posted February 5, 2009 I'm having a bit of trouble understanding what you reall want - take a look at the screenshot below, is this something like what you're after? The white line between the cheese doodle shape and the square is my edition (it was yellow in my ACAD ) Quote
magwea Posted February 5, 2009 Author Posted February 5, 2009 Sorry for being unclear. but yeah, that's what i was after. Care to explain how you got arc. Quote
Tiger Posted February 5, 2009 Posted February 5, 2009 Sorry for being unclear. but yeah, that's what i was after. Care to explain how you got arc. no problem, it's not easy to explain stuff, that's why I asked for clarifications I gotta admit though - I just started the ARC command and drew it where it looked good Quote
magwea Posted February 5, 2009 Author Posted February 5, 2009 Messed around using the Arc command there, not too good at eyeballing a drawing and got some very mixed results alright. As far as i can tell the centre of the circle has to be on the horizontal extension of the rectangle to avoid cutting into it. Can i do this using the Arc. Suppose Start, Centre, End but that's messy. There must be a better way, i hope. Quote
Tiger Posted February 5, 2009 Posted February 5, 2009 ok, I messed around a bit more with this - and the easiest way I found to get the result is to use a Polyline - here's step by step what I did, and the result looks like the image I posted earlier Started PLINE First point: the bottom right corner of the rectangle second point: top right corner of the rectangle press A to change the line to a Arc third point: midpoint of right arc of the cheese doodle. The center of the arc is not on the horizontal line though... Quote
eldon Posted February 5, 2009 Posted February 5, 2009 I think that this is one of those cases where there is no clear cut graphical solution. You can be systematic and draw a sucession of circles and get very close Quote
magwea Posted February 5, 2009 Author Posted February 5, 2009 Thanks Tiger, the polyline method works well. Never drew an arc with a polyline before: very interesting. eldon: suppose, since there is no fixed radius to insert, it makes kinda more complicated then it really is. Although, i'd still be hopeful for some systematic way of going about it is out there. Quote
