Happy holidays all! now for a question :-)

1,Draw a square, (on top plane), 100mm x 100mm then extrude 10mm, one thick floor tile, lol.

2, Draw a square, (centrally on top face), 50mm x 50mm then extrude cut 10mm, floor tile with square hole in the centre.

3, Draw a square, (centrally on top face), 75mm x 75mm, add a 5mm radius to each corner, select all and offset bi directionally 4mm, change centre lines to construction lines, then extrude cut 8mm, floor tile with square hole in the centre and a groove on the top face. This should give you a groove 8mm wide by 8mm deep with round corners, (looking at the top face).

Now my question, the resulting groove, (looking from the right, left,top, bottom planes), is square, But I want a shape that has a rounded bottom, (not a women, well not right at this min, well ok, if I must!, lol).

A U groove is what I want, but bugger me, I can not find a way to do it!

I know I'm being thick and there is a simple answer, but hey, it is xmas, Hic! Hic! Stagger! Stagger!

Happy new year to all you SW etcha-sketch peeps out there

 

Are you saying you want a groove that would be cut with a ball nose endmill.

If that is the case you have a few options. If you back up a bit and use a
cut sweep instead of all those cuts draw the profile of the groove and make
a path for it to follow.

or you could do a full round fillet on each leg of the groove.

or you could do a regular fillet using the bottom edges and half the width
as your radius.

or you could do a regular sweep of a sketch that represents the material
that needs to be filled and follow the interior contour.

Sweep cut, that was what I was looking for, Doh!
I have just upgraded to 2005 and having trouble, finding my way around, lol
It was wasn't shown in the features tool bar, so I forgot it even existed!
Only four days since I used SW 2004, forgotten how it works already!, lol
I must be having a great xmas Hic!
Many thank CS.

 

I did it by changing the separate segments to a spline(fit spline, on
splines toolbar), seems to work!, lol

 

Watch out for the splines, though. You can't dimension to them and the faces
that you would have with straight edges and radiuses end up being one face.
They could also cause some problems for CNC work, since they might have lots
of little wiggles that the program tries to follow, slowing it way down.
