alingment of parts on centerlines

N/A

I am trying to use these imported DXF files to lay out a worm gear and worm, I looked
at the help file to try an figure how to get them lined up on centerline with no
luck. There should be .500 between axis of the two gears but I keep coming up with
5.7?? something. I would like to produce a nice drawing with two/three views showing
the shaft bores in the surrounding frame but seem to be unable to figure it out.

Thanks in advance,
Kristin

Kristin,
You can easily move the geometry of the gear aroung by fence selecting it
and dragging it. You can also do precision move using the Move command. The
Move command will ask for a from point and a to point.
I have made modifications to your file. The file was saved in 2D Drafting
V20.
You state that the distance between the centers of the gears should be .500.
Based on your current design. I believe the distance between the gears
should be .5625. This is the distance from the center of the gear to the
center of the pitch diameter of the outer teeth on the gear. This pitch
diameter should match and have the same center as the pitch diameter of the
worm. In the geometry to the left, I separated the geometry of the two gears
by fence selecting the gear geometry and moving it away from the worm. I
have placed a dimension that shows the distance from the center of the gear
to the center of the pitch diameter of the teeth of the gear. This distance
is .5625.
You can now move the gear into the correct position with respect to the
worm. Fence select the geometry of the gear. Click on the Move command. It
prompts for a from point. Highlight, but do not click on the pitch arc on
the teeth of the gear. Then move to the center of the pitch arc. You will
see the center indicator. Click on the center. The gear geometry will
connect to the cursor and you are now dragging it around. Click on the mid
point of the horizontal centerline of the worm. The gear will be moved
there. The pitch diameters will be aligned.
If you want the pitch diameter of the gear teeth to be .0625 below the
center of the worm, simply place a point .0625 below the mid point of the
horizontal center line of the worm. Locate the point placed as the to point
for the Move command.
Hope this helps.

Rick B.

Thanks Rick,
I went back and looked at the specs on the gear and now see it is .5625, I thought
the PD was .5 so I can see the error in my ways. I am going to print out your directions
and give it a shot they seem very clear.
While I am at it, are there any stock templates for mechanical components like fasteners
and the like either hidden somewhere in the installed program folders or downloadable
on the website? As far as starting a new drawing what is the difference between
the two options is it just a blank page or a page with a border and title block?

You can tell I just got this downloaded and only have about an hour's time on it
so far.

Kristin,
There is a large library of standard components for electrical, piping, etc.
delivered in the program folder. I believe you are asking about bolts, pins,
etc. We do not have these in the 2D library at this time. However, with the
purchased version of Solid Edge there is a full 3D library of fasteners.
Please work through the tutorials. It will help you understand the power of
associativity. If you are not familiar with a fully associative system, you
need to step back and look at modeling from another perspective than what
you may be used to. You do not have to use precision keyins at the time the
geometry is placed. You draw the basic shape and then use dimensionsand
constraints to push the geometry around.
One key to being successful is to turn on Maintain Relationships and
Relationship Handles. These enable associativity and are explained in the
tutorials.
Have fun.
If you have any questions, please post them to the news group.
