Simply change origin of 2D PCB

Hi, 

I'm drawing a pcb that has some LEDs which will face some holes on plastic enclosure.

It's ok for schematic, pcb, putting inside enclosure and edit pcb in place too.

At the last point, I need to realign everything to be able to produce reliable(for pick&place machine and pcb manufacturing), because grid options are not perfect while editing in place (maybe I'm net prof yet about it).

As a question, it would be perfect to change origin point to edit those measurements easily.

I had used about 7-8 years competitive PCB design software and there was that option too.  

Thanks for replies,

Neco

Hi, @necoinside 

 

Please forgive me if I have understood wrongly.

When moving 3D package in 3D PCB, one way is frag to move and another way is change the X/Y distance you want to move directly in the command panel, the unit also can be changed to "mil" which is always used in PCB layout design.

Or would you want to make a unified "grid setting"  experience during dragging in 3D PCB?

 

Thanks,

Yiqiu

Normally you start to draw from zero point to the plus.

Than you make changes to minus side too. If you put thing depending on exterior design(like a plastic enclosure), your electronic components may move to the strange coordinates (like 12.32658, -3.987561). This is bad for pick&place machine and also for pcb manufacturers, maybe point hundreds are acceptable. Also minus things are mixing their head too. 

As a simply solution, I can select everything and move group. But for complex designs, you have to lock some parts and move group does not move them. 

At the other hand, sometimes you need to arrange some parts according to some other part (or a fiducial point on pcb). So calculating every coordiante of every part is hard. It would be so easier if you change zero point to another coordinate (so every parts' coordinates will be changed).

 

I hope I could explain(English is not my native language, it is Turkish).

 

Best wishes,

Neco

Hi @necoinside ,

 

I hope you're doing well. In Fusion 360 electronics the origin is not moveable. You can use the mountsmd.ulp that comes with Fusion 360 (Click the Automation menu and then select the Run ULP option). The ULP uses the absolute origin as 0,0 and refers everything to that. Now you may think, that's a problem because my fiducial is what I want to be 0,0. As it turns out manufactures can shift the origin in the Pick and Place machines software to be whatever component they want. So they can set the fiducial to be 0,0 and an offset is then added to all of the components to compensate.

 

Let me know if this makes sense.

Hi @jorge_garcia2 ,

 

Thanks for the reply.

It is more for me than machine. We have our own (and sadly a bit old/also expensive) p&p machine that have those issues. Yes, it refers the coordinates of fiducial we show but it is not only about being a zero point, also about grid snapping. Fusion 360 Electronics have solutions for my problems but they are not most practical way to use nor professional for electronics designer.

"I think developer team needs to stop thinking as mechanical designer." (Just a self opinion)

So these options (changing zero origin and more easy usable snapping grid in "edit in place") would be better I mean.

I really lose energy, time and morale while designing circuit board with Fusion360. It was really practical and fast with other programs.

 

Best wishes,

Neco.

Hi, @necoinside 

 

Seems here are two problems.

 

The first problem is about coordinates, What about have a try with "Mark" command? Type in "Mark" from CLI area and then put a coordinates mark on the board, after that, new position reference would appear.

The second problem looks like about snapping grid in 3D PCB environment, we don't have unified moving experience like snap on grid to move, the only solution seems to input accurate value and unit in the command dialog, as I mentioned in the previous reply.

Maybe we could consider improve this area in the future. Sorry for inconvenient here.

 

Thanks,

Yiqiu

Thanks for help. I think for now I have to go on long way again as your mentions.

 

I've tried "Mark" but component preferences are still depend on exact zero position so I do still need paper, calculater, effort and time.

 

For the second problem, I have to say I need to move parts by eye to put in an enclosure(or over a photo). So exact coordinates are unknown and when I move it by hand, coordinates are becoming out of grid resolution. So I have to move it first, than enter coordinates(to round numbers). Actually there is (kinda) grid snapped move (by setting increment steps) but it works only with one axis move. If I handle middle square to move, it doesn't work like this.

 

Anyway, those are just my mentions that can improve designing quality of mine.

Thanks for having time.

 

Best wishes,

Neco

Hi @necoinside ,

 

One thing you might want to explore is the Canvas feature in Fusion 360. You mention placing object over a photo. You could create the 3D PCB insert the picture, move the components to match the picture and then push that back to the 2D PCB.

 

The Canvas feature is under the INSERT section of the Solid submenu. Check it out that might facilitate things since you don't have exact coordinates to start with.

 

Let me know if you have any questions.

Hi, @necoinside 

 

Per your requirement, we have developed a new feature in 3D PCB environment called "Use 2D PCB grid". By default, this option is checked when invoking the move command in 3D PCB.

Meanwhile, a small improvement also has been done, during moving of the device, hold shift key would snap the center of the device to the cross of grids when 2D PCB grid is used.

Would you please update Fusion360 to the latest version and then have a try? 

 

Thanks,

Yiqiu
