3MF files, origin, and arrange all models

[jhalewood 0]

Hello,

 

I sometimes create fusion 360 models for a complete project with parts where they need to be relative to others; i.e. a single body/component origin in fusion 360 can be anywhere.

 

When I 3D print from fusion, using 3MF, the part goes across to Cura which respects that origin, and it ends up well outside the build volume.

 

If I then attempt to 'arrange all models' all it does is arrange X & Y, but ignores Z if Z is outside the build volume (if Z is inside the build volume now, it'll drop to build plate, but not if it's still outside the volume after arranging X & Y).

 

Not arranging Z if it's outside the build volume after first arranging X & Y seems like a bug, but another useful option might be to have a preference setting in Cura to optionally ignore 3MF location settings when importing. Some people may want that, and that's fine, but I never care about original part location on import. I always want to 'arrange all models'.

Fusion 3D exports files with objects' transform origins in different co-ordinates to what Cura uses, which is why things appear in the wrong location upon loading the file.

 

There is an easy way to drop all models to the build plate though: once you've opened the 3mf file, press Ctrl+A to select all the objects, then click the move button in the sidebar and set Z to 0 (and then turn on drop down model if it isn't already on might be a good idea) and it will affect all of them.

Hello. 

 

On the flip side of things, 

 

 In 5.4 when I import multiple parts exported from F360 in 3mf format, The models will be position correctly as per in F360. 

But in later versions, importing the models in 3mf just centers them all. I need to print a multi part model as one.

 

I cant find, but is it a function that can be turned back on?
