sketching question -- how to connect the ends of two curves together

itchytoes — Sat, 13 Aug 2016 15:04:46 GMT

Hi --

I have two spline curves in 3D space. How do I connect one of the endpoints of one curve to an endpoint of the other curve and just turn it into one point and have a smooth connection?

Thanks

Betty

Hi @itchytoes.

The process to do this is to

make the endpoints coincident
add a "smooth" constraint between the two curves.

However, after this, the two curves are still separate objects. Fusion does not have a way yet to merge them into one. This is what @cekuhnen and others have been asking for as "Rebuild Curve" or "Refit Curve". We would like to do that, definitely, but it is not yet available.

For some reason, screencast is struggling just now to upload my video. When it finishes, I'll add it here.

Can you show a screenshot?

@itchytoes What @jeff_strater wrote is spot on - however if the splines are in the same sketch it might be better to draw the shape (2 splines + blend spline) with a new spline.

the 3D sketch function in fusion is not easy to use

Hi -

Thanks for the replies. I think that in my brain, I wanted to make them coincident, but I couldn't figure out how to do that in the UI.

So, I do I make the two points coincident? I couldn't figure out what to click.

Also, how do I constrain it to be smooth at the join?

Thanks

Betty

Hi -

thanks for the reply.

I ended up doing the @jeff_strater suggestion of just making the two points coincident. I couldn't quite figure out how to make the two curves have a smooth constraint but it didn't matter. I could move the coincident point around and the line would be smooth enough for me to make a pipe.

Thanks for the reminder, @itchytoes. For some reason, Screencast refused to upload my video over the weekend. I just checked, and it is there now. There is a "smooth" constraint that will do the trick.

Dear Jeff,

Hi @itchytoes.

It was in 2016 and now we have 2018 and we aparently still do not have the option are talking about here. It seems so obvious to have it but somehow F360 developers team don't see it:/
