Circles imported into fusion are not closed .dxf

[abadsvt]

Hi,  I have a customer who provided me an .ai file.  In AI the circles are complete.   When i save as .dxf and import into fusion the circles are not closed.  Can't extrude them.  Any idea how to fix this or how to export properly?  I have attached a picture showing what im talking about.  They are a complete circle but not connected to create a sealed circle.  Thanks

Can you share the Illustrator file?

Edit Sketch, Check that the Show Profile option is ticked.

Window select all, and move to sketch plane if that option exists in the right click menu.

Circles don’t have boundary points, 

Imported geometry is a time soak.

Might help….

Hi,

This is an example of what I posted a couple of weeks ago. If you import a compatible file into Fusion,

in this case a dxf file, then it should be actually compatible with known behaviour. One of the simplest

things in AutoCAD is setting up polylines to join lines together. If I join the lines up in AutoCAD then save

the dxf file - why does the file lose this information when it is imported into Fusion? dxf is supposed to

be a vector file, as are svg files. Fusion is supposed to recognise and use vector files so why does it not

recognise this information. I get it if Fusion does not recognise svg files because they are not native file

formats, but AutoCAD is Fusion's big brother. There is no real excuse when all of the proprietry information

needed to make a file format completely compatible is available that it isn't used. This is especially true

when Fusion is advertised as being compatible with both svg and dxf files. Yes I can load them into Fusion,

but unless I can actually USE that geometry without major modifications and tweaking means it isn't really

compatible. In fact using svg and dxf files is really no better than having a canvas. If all you want me to use

these files for is a canvas then fine - tell me I am restricted to a canvas, don't say it is "compatible" when I

cannot really use it.

I know this does not answer your question but the devs do look at these forums and this is a prime example

of a user thinking compatible means they can do something when they obviously cannot. I had exactly the

same problem with importing a fairly complex AutoCAD dxf file a few weeks back and every time I copied out

the bits I wanted from this file, checked it that it was polylines and all joined up, saved it as a dxf then imported

it into Fusion, all that work was lost. Circles turned from nice clean vector polylines into masses of short line

segments, each of which were straight. Vectors are supposed to create formulas for the software to use to

describe a curve so that it can be re-created as a curve accurately. Fusion might do this internally but when it

comes to importing "compatible" files it seems it doesn't. All of the work I did modifying my AutoCAD files

turned into a massive re-draw in Fusion using projected points from the imported dxf files. It was about the

only useful information I could get out of the AutoCAD files except for scale information.

As a user, one of the most important reasons I want to import a dxf file is so that I DON'T have to redraw all of the

information and I CAN use the imported file to extrude and do other things like use them for a rail in a sweep

or something. So far, with and without help from the community and this forum, I have not been able to do this.

This is not a lack of knowledge thing, it is a Fusion just can't do this thing. Unfortunately you have been caught

like I have. You are almost certainly going to have to use your imported dxf as projected points and redraw it in

Fusion to make it work.

It does not look like there is a single arc or circle in the sketch you attached. Looks like all splines in the sketch so whatever program you're using to convert the ai file is either not doing a good job or the ai has no arcs in it. Can you share the ai file?

Probably best to create a new sketch and use the import as a reference and create 3 point circles in Fusion. Not going to be a good idea to extrude the spline to create bodies directly as it will create more complex geometry than simple arcs will.

When creating the new sketch in Fusion be careful to only click on the points so you don't get the splines projected into the sketch as you create the circles.
