3DPOLY import in FUSION

[salvatoremecca]

Dear Community,

I have a 3dpoly with thousand of vertices (it is a conversion from a GPX file) and I would like o import it in FUSION in order to manage it (make some extrusion).

I've tried to import as DXF but I cannot, for my understanding I can import a dxf in a plane, How can I import a 3d line with Z coordinates and work on it?

Attached you can find the top view and front view of 3dpoly I want to manage.

Thanks in advance

Hi,

Unless the new fusion updates have solved the ongoing problem it is highly unlikely you will be able to import a

3Dpoly successfully. Especially one that has been translated from third party software.

AutoCAD DXF files when imported into fusion often import as a mass of short line segments instead of smooth curves

and lines. This makes it almost impossible with a complex shape to create a single line without massive hand editing.

There may be another way to do this but importing as a DXF is probably not the way. SVG files, that are also supposed

to be vector graphics files, have recently been updated in fusion. SVG files would often behave like DXF files when

imported (import as a mass of line segments), so it may be worth a shot at using this method. I would however NOT

try converting with a third party first. Either do it natively or a conversion will almost certainly break somewhere.

Cheers

Dear Andrew,

thanks for your interest and answer, how can I import svg with the height indication (z axis)?

Let assume I can simplify the 3d poliline , or consider a trace in svg, how can I import in Fusion?

SVG is a vectorial trace that do not have the indication of Z axis...

Instead of importing from a different format is possible do draw directly a 3d poliline in Fusion?

I can draw sketches in one plane, but how can I draw a 3d line for example from point with coordinate (0,0,0) to (1,1,1)?

I share the process to convert GPX file to 3d poliline, maybe can help someone:

GPX is an XML file readable with a normal text viewer.

Importing the GPX file in excel is possible to manage latitute, longitude and elevation coordinate.

If you arrange all data in the style:

lat1,long1,elev1

lat2,long2,elev2

etc

select all the cells and copy

going to cad program imput 3DPOLY and paste all values copied by excel.

Close the poliline at the end of the process.

In this way you can draw a thousand of vertex simply by copy & paste

Thanks again

there could be more than one issue.

first possible problem, your import scheme may not be supported.  Check if the process is even supported by first trying to import a very simple file.  one with just a handful of segments.

the second possible problem is the number of segments.  fusion doesn't do well with sketches that have thousands of segments, as it chokes up the sketch solver.

You can import 3d info in a DXF using InsertDXF. The problem is Fusion can not handle sketches with thousands of lines\curves, doesn't matter if it's 2d or 3d, Fusion's sketch solver just can't handle lots of info.

Attached is a 3d DXF that imports no problem.

Another problem could be if the info is a long way from the origin.
