Placement of CAD Components

[[To...]]

Would someone be able to explain how to move a CAD component to a specific location on another CAD component?  In this example, I want to move a threaded post to a tapped hole on a plate.  The knowledge base does not have an clear example of this type of movement.

Tom,

 

 I think this feature could be vastly improved in Calypso.

I almost always do a manual calculated coordinate move for final CAD positioning. I sometimes use use the sliders to 'get it close'.

To do it as I do, simply create a circle on each one, record X+Y values o both, go to Modify CAD Entities, select one to move, move amount needed in positioning window. Same for Z height.

I use similar TRU-POS lugs in our programs as well.

 

Perhaps try the 'center' feature above ?

I had no luck with this - so i end up with retrieving features to get how much i have to move it in "Transformation" tab.

Or by using SolidWorks and assembly to get correct model 🙂

Tom. I don't have access to Calypso right now, but I did this about a month ago. If my memory serves me right, you open Modify CAD Model > Positioning > Check "Target Only" and "Point". Then highlight one model at a time. Click the Position button and click a point on the desired surface. Then click a second point on the mating surface. Play around with that sequence. I'm pretty sure that's it.

I should have stated that my efforts using the Center option did not work for me

  Close but no cigar.

Please describe step by step process of something that works.

1. Import into Solidworks

2. Mate faceA to face B

3. Import back into Calypso

In all seriousness, all the CMM software that I'm familiar with doesn't do CAD translating well. Mitutoyo even has something called "fixture builder" and it is quite terrible. I'm sure you're asking here because you have no other options, but actual CAD software does this so easily.

I always do it the way Chris described. everything else is not precise enough or simply doesn't work.

For the above Create a cricle feature on the post and one in the target hole, then measure X and Y distance (it's best to set the decimal places to max prior to this, in order to get maximum precision).

Similarly, make a plane feature on the post and one on the plate and measure Z distance.

The positioning dialog you showed above is only needed if you want to move a whole CAD part or assembly relative to the simulated CMM. If you just want to position two CAD models to each other, it's better to use the Transformation tab. So open that and select the part to move (the post). I found that in newer Calypso releases the mouse selection sometimes doesn't work correctly. In that case go to hierarchy first and select it from the list.

Now enter the X/Y/Z values measured earlier into the corresponding fields with correct sign and click ok.

Easy peasy. I create assemblies within Calypso all the time.

To set the Pin to the same plane as the Suface plate.

Probe a point on the bottom of the pin.

Probe a point on the top of the surface plate.

Create Symmetry point to get the Distance (Or just do the math in the Z axis).

Go to CAD drop down menu

-----Modify CAD Entities

---------Hierarchy

-----------Select the model part you want to move (The Pin).

-------------Select Positioning

---------------Enter the "Distance" in the Z axis dialog box. (Think of the Pin moving, if you want the Pin to move down, enter a Z negative value).

Repeat the above for locating on XY axis centerline to a chosen location.

If you are working in a compound XYZ, create and alignment to aid movement of the model you select. (Except now working with circles).

In the attached image I have added Gage Pins to specific locations, as assembled.

Ok, so it sounds like it can't be done with the current set of "snapping" tools in the positioning window.

Thanks to all for the "work arounds".
