I’m looking at getting a secondhand TwoTrees TS2-20W, so today I downloaded and installed the LB trial.
As a first test, I tried to import what I thought was a simple 2D DXF from Fusion 360. The curves imported, the straight lines did not. Most of the curves were made by filleting meeting straight lines, but I don’t know if that makes any difference in how the DXF is generated.
I’ve done the method of extruding the part, making a sketch of the top face and saving that as a DXF and that imports fine. I’d just like to save myself a few steps
Does it matter if a drawing is done on the Top or Front planes in F360 ?
There are some parts missing though. Could you attach your f3d file as well? You’ll probably need to append .txt to the file name (i.e. Part.f3d.txt) for the forum to accept it.
I’ve just got to pop out for a few minutes but I’ll have a look when I get back.
EDIT:
Actually, if I open it up in CorelDraw there aren’t any parts missing:
Now I’ve actually opened the sketch in Fusion (and re-read your original post properly!) I realise that this hasn’t been projected from a face (my assumption) but has been constructed from scratch. You actually mention that your original projected version worked ok but I managed to miss that - sorry!
Did you use the “Save As DXF” method from the sketch’s right-click menu…
…or did you use the “Export…” in the file menu?
EDIT:
I’ve since done some testing and found that if you export the sketch from the right-click menu LB will import it as it should (even though it might be upside-down):
You’ll see that it’s exported using the top level coordinate system so all the geometry in your sketch is in the XZ plane (which is what’s confusing LB. Using the right-click export uses a local coordinate system and exports in the XY plane.
Interestingly FreeCAD gives a similar result to LB:
I can’t remember which method I used but I’ve just gone back to the original drawing version and made two DXFs, one SaveAs and one ExportAs and the SaveAs works perfectly in LB, plus it doesn’t require F360 to use “cloud translation”, so I will do that in future.
Interesting about the co-ordinates. When I have time I’ll do two identical sketches, one on the Front plane and one on the Top and see if the Front one always fails.
As an aside, the SaveAs DFX is 5k, the ExportAs is 88k.
I was pretty sure the sketch “Save As DXF…” had worked for me in the past irrespective of the orientation of the sketch plane but I thought I’d check just to make sure. I created two sketches, one on the top face and one on the back face of one of my Fusion models. I projected the relevant faces to each sketch, saved each sketch as DXF and imported them into LB.
Mostly when I’m designing stuff in Fusion that’s going to end up in LB I create a drawing with all the views I need then export that as PDF. Exporting directly from the sketch is of course quicker if you don’t need the drawing(s) for other purposes.
