Awefully messy workplane views to align subassemblies. Any solutions?

Hi.
Like I attach, I use workplanes to adjust positions of my subassemblies.
As you see, pneumatic finger unit has two oposing fingers only, unless I create a dummy work which is cylindrical, there is no way to align each other.
Then there are so many workplanes scattered around then my view become just a mess.

How are you usually working when you want to align subassemblies?
Is there any better way than using workplanes?
Thank you in advance.

You should very rarely need to use workplanes for positioning. The Mate Align, Dynamic Position, Pt Dir PT and Match Pts should provide all the necessary functionality you need. If you have access to Advanced Assembly, there are some great tools there, if you want persistance in positional relationships.

Can you be more specific with your problem, as you were with the align of two axis?

Re: Awefully messy workplane views to align subassemblies. Any solutions?

Thank you Paul for your reply.
I am at home, and I cannot access to the software now, so I upload simpler model using PE. Please refer.

I could use face of the finger parts, but the cylindrical part is the product which I want to transfer. It will be grabbed by the fingers at middle. So the finger face is offset by half the thickness and the products should be in the midpoint of the fingers. I could only imagine to use workplanes rather than part's face in this case.

Please do advise for the better solution than annoying workplanes. If I could disallow presentation each subassembly's workplanes indivisually, that is one way. But OSM allows me either no workplanes or all workplanes.

P.S.
The both subassy are created in the same workspace today, so they are parallel, the actual model is not. They are at angle.

Thank you for your attentions.

That's not correct. Any workplane can be shown or hidden individually, for example by clicking on the toggles in the structure browser.

Claus, you are right.
But I found other issue with configuration, so I use configuration as little as possible, then every time I need to turn on and off each workplanes indivisually but it's too tedious to do. Instead I used view setting to tune them off.
The problem with configuration is unless you place parts deactivated all the parts position will be back to loaded place.

Back to the original issue, I should have put the products to the mid position for pneumatic hand chucks, so that I do not have to use workplanes to align subassemblies?

Hmmm.... I didn't mention configurations, really - the drawlist functionality in the structure browser is a mostly independent concept.

On the other part of the question, I may look into this in a couple of days (don't hold your breath), but right now it's the weekend 8-)

Does it indicate the view setting for Workplanes can be preserved for the next startup with out the help of configuration?
If so, I was misunderstanding...

It sure is.Please take your time.

But my concern is, again, if this application require workplanes to help locating subassemblies or should I make dummy work so that they can be aligned without a help of workplanes?

Sorry for my contradicting response. We're on our weekend.

No - but then, workplanes tend to be temporary helper objects, rather than permanent parts of the model, so storing their visibility status in the current session is usually even less desirable than for parts. (I'm not saying you'd never want to store the on/off state, just that it's not the mainstream case.)

I cannot comment on this particular alignment case, but I'm sure others can chime in and help you with that.

I added cube shape to my product so I can use faces for positioning purposes.
I believe your comment on the workplane use, which leads to the conclusion that there should be some reference part with wich I can align, mate, align axis....
Thank you for your comment.

Re: Awefully messy workplane views to align subassemblies. Any solutions?

Toshi,
So, this may be one of those situations where some extra geometry is necessary. I guess I will eat my words now .

This extra geometry can be geometry on a workplane, an extra 3D model, 3D wires, imprinted edges and added verticies. You might try 3D wires, it can be less "messy" than WP's. Wires have to belong to a seperate "wire" part.

Thank you, Paul.
How can I make it?
Would you upload any example of it?
Thank you again.

Re: Awefully messy workplane views to align subassemblies. Any solutions?

Here are some simple examples. In the first example I added geometry to both parts using "Imprint Edges" functinality in the Machining menu. I added "Silhouett" edges to the cylinder, and also added an edge (Line) to each of the gripper faces. Edges are highlighted in yellow. I then used Position Pt Dir Pt, to position. move Pt 1 is the center of one of the silhoutte edges, fix pt 1 is the top end of one of the added edges on the gripper face. - and so on. (if you use imprinted geometry, the geometry will be removed if you ever "Merge" the body.

In the next example I added a wire (red) so that I could find the center of the gripper, then used Match 3 Pts to position the cylinder. move pt 1 is center of lower cylinder edge, fix pt 1 is center of added wire. move pt 2 and 3 are just points somewhere on the lower cylinder edge - don't need to be too accurate with those pts.

Depending oh how you really want to position the part you may need other geometry, these are just two examples. Hope it helps.

Re: Awefully messy workplane views to align subassemblies. Any solutions?

Thank you Paul for taking your time.
I'd appreciate for your works.
I managed to inprint line to the side of the cylindrical face of my parts. Yet, I need to use it for aligning with other parts.
I have not figured out how I could sort them out today.
I will come back later to find out how to clean up my mess.

Thank you again.

Paul, I somehow could make two cylinder aligned and oriented with line printed on face.
Thank you.

Re: Awefully messy workplane views to align subassemblies. Any solutions?

Looks good Toshi. In your case above, Mate Align - Align Axis and Mate Face would give same results. But it is good practice for imprinted edges. You are on the right track.
