regarding point offset before alignment

[[Me...]]

hi can any one explain how to offset a point before alignment ... or is there any direct option called offset point

[[In...]]

You can offset a 'Plane' by using 'Plane with Offset' under 'Construction'. If you wish to use the offset plane for alignment.

Or

In "Base Alignment > Special > Offset" option is there.


But if it's "Point" i.e. only one point on a surface; i don't think you could offset it.

[[No...]]

You can, if you recall it to a second point and modify the recall formula (add offset).

Can u plz put the steps? something like "Construction > Option X > Option Y etc..

I would like to try this out 🙂

It's quite simple:

- Define a point with nominal values as usual.
- Define another point by selecting from the menu
- In the second point, select to recall a single feature and select the first point to be recalled
- Make sure the selected alignment is the same as for the first point
- All the fields of the second point are filled with formulas (yellow)
- Let's say you want to offset the point in +Z
- Right klick the nominal Z field and select formula
- In the formula editor you see the the existing formula that was put there by the recall function, something like:
getActual("Point1").z
- Add your offset at the end of the formula:
getActual("Point1").z + 1.234

Thank you, Will try it 1st thing in the morning. 😃

I have a similar issue. I am new to Calypso and I have four datum targets that need leveled. I have the original/first point then the second point recalled to single feature and the formula is set to offset point A2, A3, and A4. I run the Base/Manual alignment but when I go to run the Start/Auto alignment the machine doesn't measure A2, A3, and A4. I followed the instructions, to my understanding, but I can not figure out how to get the Auto alignment to measure those three datums. Any help/advice would be appreciated. Thanks

What feature are you using for your base alignment? Did you recall all of those points into a plane?

[[Me...]]

A1 is the original point, A2, A3, and A4 are the offsets. I recalled A1 and the offsets for A2, A3, and A4. I am suppose to recall all the points including the original A1 thru A4 plus the three offsets? Thanks

The feature is a plane - Option - Recall.

Instead of using Recall, use "recall feature points".

When I use Recall Feature Points it doesn't give me the option to recall the offset points because they are Theoretical.

Crap, that makes sense. My bad.

Can you post snippets of the features and the formula you are using?

I know what I want it to do, but I don't know the process or procedure. I have four datum targets for Datum A. I want to offset A2, A3 and A4 to A1. I created the plane with A1 and A2 offset, A3 offset, and A4 offset. But when I run the Auto Alignment it doesn't measure A2, A3, or A4 so the offset isn't being calculated. The alignment plane looks clocked instead of leveled or flat to the CAD.

Did you try using the User Guide for "Offset Plane special geometry"?

[[Me...]]

From my understanding Offset plane only works with three points. I have four datum targets I am trying to level.

Have you tried not using the offset plane in your base alignment, but just using it for the characteristic's datum structure? Or a separate alignment? I've had issues using features tied to other features for the base alignment.

Ashok Vardhana and Tristan Helton,

similar or the same as Norbert described, but with screenshots:





Repeat those steps for every point, you wish to offset.
Note that the Nominal X,Y and Z filled with formulas will only do the graphical presentation, so you could see better what you are doing. The important one is "Z - actual" one.

Dane,

The pictures you attached are not working for me, they do not display. I got it to work, but the weird thing is I didn't change my method or process. I am not sure what happened but it did finally work as intended. Live and you learn. Thanks again to everyone who responded.

Welcome to the club 🤣

By the way, some (all?) of the old pic attachments went to the bin when they updated the forum software on Nov 22nd.
