Fusion 360 help please.

This is the problem with chamfers and threads...

...the thread hasn't broken through the chamfer....

Useful information, I can see exactly what you are saying. I only put in the chamfer as a test to see if the "Modelling" option would reappear.

Presumably the solution is to chamfer the hole first, before applying the thread?

The thread is what you want to be modeled - the check box is in the tread or hole dialog where you created the thread in the first place.

Right, thank you for that. I take it then that I should fill the hole and cut a new thread with the modelling selected?

Just edit the hole and tick the box. It should then generate the thread

I'll have a go next session. I appreciate your input.

I am having trouble writing an .stl of the part I have drawn. When I put the file into the slicer, either all of the text is missing or just the F is missing. I have looked at various help files and nothing I have tried seems to help. Another option I tried was to combine the main body with the text (tools) but that achieved nothing either. If I use the text to cut the body, everything is as expected but not if it is proud of the surface.

Works OK for me - In the browser I right click on Body 1 and select Save As Mesh and ensure refinement is set to High and Binary output.

Some interesting modelling techniques though.

 

[Misterg]

You have overlapping bodies - perhaps this is something to do with the problem?

Body 1 is the whole thing:

There is also a body for each letter. I *suspect* this may be confusing the slicer:

Easiest way to correct this in *your* workflow is to edit the first 'Combine' command and un-tick the 'keep tools' box:

This brings everything down to one body again:

You can then delete the 2nd combine command as it doesn't do anything.

FWIW: If you're designing anything similar in the future, you may find it a lot easier and quicker to start by drawing the cross section of the base and extruding that, rather than drawing and extruding each 'leg' separately. This would also allow you to modify the cross section without having to resort to moving faces (something I avoid if I can).

Something really weird is happening on Extrude8 - it's somehow scaling the text as well by the looks of it.

Yes, not sure what's going on there!

FWIW, this is how I would have modeled that part:

I am coming from DSM which tends to colour my thinking about how to do something. The text placement in DSM is appalling so I did it in Fusion first.

Right OK, I supposed that it would delete the text otherwise.

Yes thank you. It didn't occur to be and it would have been simpler of course. I started with the cut out characters and then modified that to bring them to the surface. Maybe I should just have restarted it?

 

[ajlelectronics]

Much appreciated once again, thanks to everyone.

 

[daedalusminos]

This is how I would have done it....

 

[Misterg]

Right OK, I supposed that it would delete the text otherwise.

Yes, it would delete the *original* text, but the target body will have the text bodies added to it when you click OK, so you don't need the originals (in this case). If you keep the individual letter bodies as well as modifying the target body, each letter is two overlapping bodies which cause the operator confusion when trying to select things, and would probably confuse a slicer too.

I would suspect that was the issue then as you suggested. Thank you.

A test print has just been done and I got the layer wrong for the colour change, so here we go again!
