looks like you are getting the hang of it.  Did you do that as two separate drawings or did you manage to just move the center plates and have the rest correct it's self?  I seem to remember a command to locate stuff like pivot points  so you could move one part and have the rest follow, but I can't remember what it is.  <----Makes me do things the hard way.  Know what I mean?  Or am I confused?

I copied the entire drawing, then i rotated everything into place. Then i selected everything and moved it as one piece... If you move one piece you have to move everything else to match, As far as i know, if you move just the plate it will not automatically rotate the arms and stuff...

ok, sounds like what I have to do every time.  Goes something like move plate.  move arms. move spindles and tires.  Then double check all the centers line up.  Each part moved or rotated individually using the object snaps.

Are you rotating objects using the Reference command?

Looks great!

Next step make the assemblys blocks, so they move easily as one piece.

like the tire/bearing/upright, and the complete a-arm or link.

It makes charting multiple suspension travel points much easier.

Already Learned that....  ;D I got everything blocked now. When i cut that from the original drawing i did paste it as one block tho on the new dwg and saved to take the pic etc... Put in a good 10 hrs today drawing, probbaly do the same tomorrow, For some reason i am hooked on this and really enjoying it....

I draw circles with the radius the length of the arms.  The center of the circle is the center of the inner pivot.  Now chose the heigth to show the upright/tire.  Now put the lower upright mount on the intersection of the arm radius, and the heigth.  Then I draw a circle on the same point that's radius is the same as the upright mount separation.  (Draw a circle with the center the center of the bottom upright and select the center of the top mount as the size of the circle.)  Now the intersection of this circle and the circle representing the top arm are where it needs to be rotated to.  Now you can rotate easily using the reference to the exact point.

I can see you already know how to get it done.  Just sharing my method.  ;)

Circles are a man's best friend when it comes to locating stuff.  I got me a track ball cuz my arms where getting tired.
