Fusing array fail

Hi Guys I have been trying to fuse a polar part array (made from draft wb) to another part so I can model a timer that looks a bit like this one http://media.rs-online.com/t_large/F5129594-01.jpg I have tried a bunch of ways, but it keeps deleting some of the array? The fist 5 copys every time. Its ...

Re: Constrain xy sketch to z sketch?

I'm not sure I understand?

How would the spreadsheet help me change the angle and adjust all the sketches without changing the position of each sketch manually?
Say I want to change the angle to 20 deg?
Or if I want to add more sketches along the same line?

Re: Constrain xy sketch to z sketch?

Not quite what I'm looking for. Seems my attachment didn't attach. I have multiple x-y sketches that all need to be attached to a movable line in the z plane. So I don't have to manually re-adjust every one each time. This version only has 3 sketches, but I would like to have finger grips which mean...

Constrain xy sketch to z sketch?

I have been working on this handle for a bit and have been making many changes to the design. Every time I do its really time consuming to get everything lined up with the 15deg angle. Is there some way I can anchor xy sketches to something in the z plane that I can change the angle on? I have been ...

Re: Odd sweep result?

I tried to print my handle and it was clear there where a few problems. A. It was too big. B. it was a very difficult print that was going to need a ton of support structure no matter which way I printed it. So I am now working on making the 2 loft/sweep parts separate and I will attach them post pr...

Re: How to match herringbone gears?

Shouldn't those gears be the same thickness?

Odd sweep result?

I am trying to make a handle for 3D printing. I tried to use the part Sweep tool It did some extra curves I didn't want. Hopefully deleting the sweep in the attached file will make it clear what I was trying to achieve. I was hoping for a gentle bulge in the middle rather than an hourglass.... I ori...

Aply thickness to shape string extrude

Not sure if this is too big an ask or if I'm just aproaching it wrong. I would like to have extruded text protruding from a surface with a set wall thickness and a hollow inside with an open top. The idea is to be able to fill the text with something once its 3d printed. I have tried the thickness t...
