I’m having a beginner problem. I’ve created a series of ridges to sit on top of a dome. I’ve created the dome using revolve tool, and imported it into another project. When I try to Move /Rotate the dome the original arc remains, and wont move. Trim and Delete both kill the sphere.

Eventually I want to UNION the dome and ridges into a single object and 3d print it .

I’d love some help, thanks

I’ll try to attach screen shots here.

Why are you importing the dome? The is the dome not easily repeatable?

If you know the math (how many ridges in 360 degrees, simply revolve the arch of the dome to 360/x to get a slice of the dome to replicate with the pattern tool and add the parts together?

Sometimes it’s easier to make part of the thing and mirror it AND OR pattern it.

Struggled mightily to get the ridged hemisphere. Didn’t want to work around it while struggling with the dome too. That’s why I imported the dome.

(I have yet to get Mirror to work. but that’s another thing. )

I believe what you’re suggesting is to make a single piece of dome and a single ridge, UNION them, and then PATTERN? I’ll give it a shot.

Is there a way to cut a body out of one project and paste it into another?

Yes make a single piece then pattern.

I think there is a way to cut but no paste much to our mutual chagrin!!!

And are you exporting and importing in the actual Shapr format?

Thanks Oregonerd. I appreciate your patience.  
I’m finding this very hard to do. Because my ridges were made with the LOFT tool they are not perfect arcs on the flat (underside) face. I’m stuck making the “dome section” face.

As for the Shapr format? I’m only importing projects within Shapr.

I’m really looking for a way to get that arc remnant to obay the commands that the lovely dome manages so easily. then things would be the way I want. Would the importing make a disobedient shape???

Depends on what you are importing. Not much can be done with an STL file for example. I can only be manipulated in limited ways.

I’m kinda visualizing what you want to do: You want the ridge to lay as a feature on top of the dome? Connected like a rib?

Yes. The picture you sent is very close to what i need, but apparently to use the UNION tool the ridges can’t be made by extruding or they end up flat, like an image rather than dimensional.  
Perhaps I can chop up my ridge hemisphere and build the dome underneath it ( maybe again using LOFT) and I guess thats my next effort.  
I like the ridges to diminish as they converge rather than stay the same size throughout.

I’m a clay sculptor, and this is going to be a texture stamp for the fine structure in the suckers of an octopus.

Loft with guide curves. The more cross sections the better. I like to use planes on a curve. Remember you can duplicate move cross sections too.

Would be nice if there was a sweep with scaling.

I tried to make an arm with a plane at the end which I could rotate. I even tried to put a little rectangle on the plane, hoping that I could then copy a group of identical plane-and-rectangle groups. The plane will rotate and copy; the arm won’t, even with everything selected.  
I’ve gotta take a break. Thanks for your help. you’ve been patient.

Tried it a different way, ie create a single cell of dome and ridge ready to pattern. Same problem: that blue remnant sticking out that I can’t get rid of

Hi Chad Shumway. I’m not sure either what the A and B are. A is the tail of the all-important ridge.

Lets not get hung up on the IMPORT stuff. I only IMPORTed another Shapr3d project, and only worked on another project to have a clean work space. I can make the dome in the original project and avoid importing if necessary. Is it really unusual to merge two projects?

Does this have to do with the order of operations?

Yes exactly. Then pattern into a ribbed hemisphere.

No. Haven’t done it much. Some file types have limitations. Trying to understand your problem had me look at all possibilities. I can be dense sometimes. And sometimes Shapr has some “quirks”.
