Projecting Sketch Onto Surface Issue!

[Anonymous]

Hi There.

I'm having an issue trying to project a pattern of ellipse shaped lines onto the top surface of a body.

I've offset a plane from the body and made a sketch on this plane, where on I've made the pattern.

After this, made a new sketch and gone to "sketch" - "project/include" - "project to surface".

Then selected all the surfaces I want to make the projection onto and the whole pattern as the "curves".

Also I've ticked the "along vector".

Now, some of the ellipses are projected just fine to the surface whilst others are incomplete and have some missing lines.

What am I doing wrong here?

I hope someone is able to help me with this.

I have looked at other threads to come to a solution, but none of it has solved my issue with this.

f3d file attached!

Kind Regards, Jeppe Andersen

Hi @Anonymous,

May I ask, what do you want to do with the projected patterns?

Cheers / Ben.

Hi Ben.
I'd just like the pattern to kind of "blend in" with the top surface of the body, so that I from there could make a toolpath for instance..
Any thoughts?

Kind regards, Jeppe

Hi @Anonymous

The problem seems to lie in the surface you are trying to project onto. In Patch mode I have used the patch tool to create 4 new bodies which represent the surface in a much "neater" fashion.

The projection then works. I think the warning message that still arises is from the fact that some of the ellipses fall outside of the face.

Excuse the somewhat lengthy screen-cast attached which details the above procedure.

Hope this is of assistance.

Regards

John

Hi Jeppe,

I'm more interested to know about the end game? Are you going to use the Sweep tool somehow? what the Model will look like?

I'm asking because, it is not recommended to pattern sketches. It is much better for performance to pattern a Feature instead.

Did you get this idea from @curtis.chan  youtube vid this one https://www.youtube.com/watch?v=VmJdHOxDLCQ

A surfaces like what the F has is A bit tricky at the moment what @Anonymous shows works, if it works run with it.

but playing around with it some can not hurt ever, things like this will get better over time.

Hi johnKLUQK. Thanks very much for taking your time to do this! This was exactly the outcome I wanted. Thumbs up!

Hi Ben.
I appreciate your comment about making a feature and then a pattern from there! In this case though, I haven't been able to make it work. But will give it another go. But yes, I was looking to do a sweep after the projection to try and make the part look a bit like the video that "daniel_lyall" has shown below. Thought it'd be some good practice anyway.
johnKLUQK seems to have come up with a pretty good solution in the end 🙂
