unsynced sketch and model grids

[jbarchuk]

I'm a super-newbie as regards F360 but have very intense previous experience with PCB CAD, for instane doing 3-views of sheet metal enclosures and such, so I do know how to drive a new vehicle around the block and figure out how things like the lights and wipers work. Aside from pure practice pieces following some demo vids this is the first part I'm working on that's intended for use in a real product. If it were a simpler part this problem wouldn't bother me but it's intended to be mounted on another part plus other related parts and all must be oriented properly and acurately.

I've added 4 pics below to visualise the issue. RATS llimit 3 so I made it 4 and compiled them into 1. I could have added 2 more frames but the issue should be obvious with these. RATS the preiview doesn't show the image os if it messes up I hope there's an Edir feature. Oh well.

The first frame is a sketch that shows vertical and square to the origin.

The second frame is the revolve.

The third frame is after orienting with HOme, Top, and the zooming in a bit. Notice that up to this point the grid in the background stays square relatie to the screen.

The intent is to add a square hole in the top of the part. I select Create and Box. When I select the top object it goes to translucent. However the -Sketch- grid is skewed. When I create the Box that shape is oriented to that greid. When I hit OK tha box stays skewed, and is skewed in orientation to the Model background that appears.

I went through about a dozen rounds of undo--undo-... back to differnt levels to try to find a different workflow path that doesn't skew the Sketch grid and the square hole. Each time the results are exactly the same, and joy <-- zero. I can't even find any option that offers to rotate the Sketch grid relative to the Model grid. I do see an Align function but I couldn't find a way to make that work. Either way, I'm -sure- I never used anything with Align or any other kinds of rotates or revolves.

Any clues? TYIA.

Oh BTW by -selecting- the object in order to add the box changes the surface color to an -opaque- blue, but I got past that to see the grid behind it by changing the material to Glass.

Hi Jbarchuk,

Thank you to choose Fusion 360 as the design tool in your work. 

For the issue you met, we tried to reproduce in our side. Unfortunately, we cannot reproduce it any more with the steps you listed. Did you meet it every time with this workflow? Or just with this file (I realized you have tried dozens of times to create the square hole, but got skewed finally)? If you can reproduce it all the time, that we may lose some special details when trying to find the way. If it’s file related, can you share with us your design file?

If it’s possible, please share this design file to me at jinhai.zhu@autodesk.com for further investing.

Thanks very much,

Gavin

Well, -I- didn't exactly choose it. 🙂 I'm involved in another project, and some people over there are into F360 so I'll go along. It's weird and non-intuitive, but very powerful so probably OK.

> Did you meet it every time with this workflow?

Not the first time, but somewhere down the line. There were mmm... I'd guess about half a dozen instances where I had to go back to the Sketch portion using undo-undo..., edit it, and continue further. At a point I was happy with things I went back to the sketch, saved it as a file, added diferent versions number along the way, and continued further. The file mentioned below has a 03 in it because that was how many versions I saved.

AHHH HA! I just had an enlightening moment while writing thta paragraph. Of the 3 versions I saved, I just loaded version 02, went through the select, revolve, and Model - Box steps, and the grid misalignment did *NOT* appear!!! This is a *CLUE*! This means that 'something' happened to the file between versions 02 and 03.

> Or just with this file (I realized you have tried dozens of times to create the square hole, but got skewed finally)?

Actually not dozens (plural) of times but there were a few possibilities definite under a dozen. For instance I could select the axis and planes in a different order, or after doing the Revolve I could do the viewing steps to get -to- the Top view in different ways. When -all- of them -always- produces exactly the same effects I decided I had to go back to the Sketch level of workflow to find out what was wrong with the file at -that- time.

> If you can reproduce it all the time, that we may lose some special details when trying to find the way. If it’s file related, can you share with us your design file?

Soooo what I have done is upoaded -both- the 02 and 03 versions. With that you may have some analysis software that can find some corruption detail in the binary file format that could cause the error.

V02 is at http://a360.co/1vhi5Wp

V03 is at http://a360.co/1zYncA0

BTW those are *MY* version numbers in the *FILENAMES*. I notice that the software is adding V numbers at varions times, I -think- when I am doing 'save as' rather than just 'save.' I haven't gotten far enough into the docs to see what's going on there but I tend to ignore them because I find it EXCESSIVELY annoying that the software muck aroung with *MY* filenames. 😞 :(.

DON'T CHANGE MY FILENAMES! I'M A BIG BOY AND KNOW HOW TO KEEP TRACK OFTHINGS! THE SYSTEM USES 'name V1 V(x)' S P A C E S WHICH IS *EXTREMELY* *NIX-UNFRIENDLY!!! YES I'M YELLING!!! DON'T SCREW AROUND WITH **MY** **FILENAMES**!!!! I'll look in the docs but if I can't shut that silly thing off it's gonna take me a million years to learn how to deal with it.

BTW please don't take all that YELLING personally. 🙂 I should have been clearer that. I'm not yelling at -you- Gavin I'm yelling at *Autodesk* and the ummm... 'user interface designers' who thought it'd be an RCI (Realy Clever Idea) to step on my data without telling me. 🙂

Thanks Jbarchuk,

Your information is much clear and useful, also thank you sharing the V02 and V03 to us for investigating. Have sent this issue to our Dev to analyze.

For the file name saving in backend, it's really the design in Fusion 360. Also include our product designer to consider your option.

Regards,

Gavin
