Projection in a sketch from another component 1

[CAD2015]

Hi,
I am working in an assembly. I want to project curves from another component in a sketch of a new part.
"I got this error message:

Projection onto the skect failed; the selected elements cannot be projected"(See the attachement)

Should I undesrstand that it is not poosible to create a sketch using projection from another assembly?

Thanks

this question was asked recently, but I can't find the thread to refer you to.

You're probably getting that message because the geometry is not published as required by your settings.

So, you have two options:

1. Publish the curves in the other part first, and then you can project them, or

2. Tools + Options + Infrastructure + Part Infrastructure and turn off the RESTRICT EXTERNAL SELECTION WITH LINK TO PUBLISHED ELEMENTS option in the General tab page.

(I recommend the first option)

Thanks a lot, Jackk!

so which method did you choose? (and thanks for the star!)

The second one.......! Also, I read other related threads and I found the "Create Datum" tool very helpful! If I click on it, I can get in the sketch I work on the curves I need from another assembly component! Unfortunately, at the moment I am still confuse about how "Create Datum" allow this procedure. Any help in this direction would be fully appreciated!

Thanks!

Somehow I knew you would choose the turn off the Publishing restriction.

Create Datum is another option.

With the Create Datum turned on, everything you create is isolated (with no history, with no links). So when you project geometry from another part, the original sketch geometry is copied first as an isolated, datum curve with no links, and this isolated curve is then projected into your sketch. The Create Datum option is another way to avoid links when working with multiple part components within an assembly.

I like using links and associating geometry, so I never use the Create Datum feature.

Wonderful, thanks again!

Jackk,
Can you describe me the main steps in using the Create Datum" feature?
I mean, in which component should I kit the "Create Datum" icon?
1)In the one that I want to bring the projections?
2)In the one that I want to get projection from?

Thanks again,

my advice: never use Create Datum!

(links are good)
