Radius to Radius

[R. Wink]

I must be missing something simple, I guess. I have a part I'm trying to dimension that has a radius on both ends. Flat
part with no straight sides where I want to dimensions. In Acad, you could type "quad" from the command line and pick the
extreme edge of a radius, the using the "quad" command again, pick the opposite radius for a dimension from extreme to
extreme. Is there something I'm missing? BTY, I'm using 2K3

Hello towarts you.

What you are able to try is able be done. Make first one dimensions from
arc from to arc, but recalling to make pick on these acrs (never on centers
for it not works) - this you must for this to work.

Once complete, now then go to properties of dimension by right button of
mouse.

Now look for to see these button called of conditionals of arc "center max
or min".

Here you then select. Now is made like quatrants of program before.

Pluswise, every the versions of solidworks can complete this since long past
time.

Sincerefully,

Habib

As I understand ACad (which is minimally) the quad command acts along the
axes of the coordinate system

The SolidWorks nearest equivalent, described by Habib, is different and
arguably more powerful, because it delivers the result you want even if the
centers of the radii are 'off-axis' or slanted relative to the coordinate
system.

Unfortunately, you are correct and incorrect. I used the method and it does work..however it ignores the present axis and
dimensions for max to max. I have a part that is 13" lg with a 3/8 radius on one end and a 1/4" radius on the other. Both
have tangent angles toward the center of the part. The method outlined results in an angular dimension..Not parallel to the
current axis, resulting in an incorrect overall length. only differs by about a thou or so but it's still wrong.
If you take the dimension from center to center and add the radii, the dimension is different than what SWX comes up with.
Try it with a 1" and a 1/8" radius..it's greatly magnified.

Ops!

For also now then you need make one line of coustruct. This line make make
4 coincidences 2 per the center of arcs now then two per endpoints upon very
those same arcs. But then you make dimension upon this made line.

But this only way I am know to do now.

Thanks to all who replied. Andrew sent a private mail and I want to thank him directly.
Turns out what I was trying to do is real simple..place a dimension, RMB for first and second arc conditions (max) then RMB
to pick horizontal dimension.
Now my question is..how can I make this condition the norm rather that having to go through all the RMB's.
