I"m trying to make a on plane relation come up so I can run a structual tube cross member between the legs of this jack stand. But not having any luck getting the relation to appear.
What am I doing wrong please ?
When working with 3d sketches you can use 3d sketch planes to make your life a lot easier.
One thing to note is that 3d sketch planes are unconstrained, so the horizontal can rotate.
When a plane is active (you see the grid) an on-plane relation is auto added.
dbl click to activate / dbl click in empty space to deactivate
It's pretty easy when you get the hang of it.
As others have mentioned though, if you dont need a 3d sketch why use one?
You need a 3D Sketch, not a 2D one.
I'm in 3D sketch.
Still no on Plane relation.
What am I doing wrong ?
Select them both (CTRL+click).
When I CTRL Click each one I don't get the on plane relation.
1) Make sure you have nothing else selected
2) Make sure that there aren't any other constraints limiting the line

Here's where I'm at. Of course I'm not sure if I'm doing this right but the examples other members gave me did give me the correct clocking of the legs of this stand. So I modify the approach.
Then, after I shut down my PC last night I found the on plane relation was getting more easier to achieve for some reason. It's not uncommon when I'm having problems trying to get certain aspect of sw to work, after a shut down or reboot it some times seem to improve the situation.
Now that this morning I'm able to bring up the on plane relation. In the first two cross members I got it to activate. But the last two the on plane will not activate.
Anyone see the problem ?
I believe I've mentioned before that it's generally better to avoid 3d sketches unless there's no good way to avoid them. One of the reasons is the difficulty you're facing here. It's orders of magnitude more difficult to control relations and just generally fully define 3d sketches than it is 2d sketches.
It looks like you're trying to place horizontal braces joining the legs. If that assumption is correct I'd suggest a different approach than the one you're attempting.
Here's the file, that is if I up loaded it correctly.
Since you are that far in your model, I would place a Plane at the 16" Level and delete those dimensions. Then I would use that plane to add a 2D sketch and then add a short line connecting the tangent edges of the tubing and make the end points and the edge a Pierce Relation. Then I would draw a line from center point to center point of those small lines...
That is one way..
In reality, my workflow would be to create a SSP and then add the weldment components..
Have you checked the new Structure System functionality in SOLIDWORKS. No more need for sketches for defining structural members!
