Edge route part of shape

[interloper]

Hi. I was trying to round off 2 opposing side of a square using round over bit. I needed to maintain my dimensions. I like the function of the "cut path" to compensate for the bit diameter, but don't see option to choose the bit for this. Is this possible? Thanks!Edit: Also I was wanting to round off 1/2" board with the 1/2" round over, but I need the round over to plunge in more for a full profile. I'm only allowing to plunge .55 inches for a partial round over.Thanks in advance

There is a choice to inset the bit from the path but that is only for closed paths. There is also an offset path in the 2D Vector Drawing add on. Otherwise I think you have to offset the path yourself. Snap to grid my help with that.

So I guess I have to route it the "old-fashioned" way?:/

I am sure you can do it. If you post the mpc, we can probability help.

It's just a 5.5" square hehe.But wanted to maintain the dimensions with parallel sides rounded off

I'm not sure if I understood you correctly. Maybe something like this?

[interloper]

Yes, I tried the same thing, but that side is no longer 5.5 inches.
Also tried offsetting the two lines and got close but then lost the full round over because I could get it to plunge deeper

Thanks

Are you trying to keep the inside or the outside?

[interloper]

The inside 5.5" square.
Seems crazy that it's difficult, doesn't it?

I used the 2-rail sweep for this. If you don't have the 3-D tools I can save it as a pattern for you.

[bergerud]

You just have to make the line 3/16 from the edge. The problem is that your board is too thin. The 1/2" roundover routes deeper than 1/2". You may have to make the Designer board 3/4" and put your real 1/2" board on a sacrificial sled. OK just use a router!!

Edit: Good idea Steve.

[SteveNelson46]

I think Bergerud is correct. It might be better to just use the table saw and a router/router table. It certainly would save alot of wood.

EDIT:
If you have a specific project that you intend to use this idea on, let us know and maybe we can help.

The MPC says corrupt for me. I'd like to see what you did though.
I don't have 3d. I'll go ahead with standard router. These are for some speakers I'm making. -New found use for the ol' carvewright :)
Thanks folks

You should be able to open this one if you have Designer 1.186

Agree with Dan,, table saw and router... Save wood and time ...
