In 3D mode with ViaCad 16 Pro.

No constraints enabled

Normal work plane (front, top, or side)

Polyline tool enabled

It's not possible to draw more than two segments by directly entering the coordinates.

This works perfectly in 2D mode.

Is there a specific technique for this?
Thank you for your answers and tips.

Hi Martinraujl,

I work with Windows Sharkcad 14, build 1625 and no problems with it.
Perhaps you have to look at the preferences/user interface and select or unselect "use workplane coordinates in data entry"

Maybe this helps?

Regard, Theo

If you've got the list of coordinates, it can be drawn as a 3D polyline by .spl file import, very simple text format. Head the list with POLYLINE, then one coordinate, tab delimited (tab between values, not commas or other punctuations), per line and give the text file .spl as the file attachment, then File|Import|spline and choose your text list. Maybe a workaround to whatever issue you're experiencing, a powerful tool in its own right.

Good idea. You apparently get the points by displaying them with selecting and Ctrl+D. AND then you can draw the polyline and discard the spline curve. As far as I’ve tested, this doesn’t work with Edit > Change Object Type.

If POLYLINE is declared on the first line of the .spl file, that's the object you import, not a spline. You get a spline if you haven't put the declaration in the first line. Other entity/object types are also declared at the first line, THROUGHSPLINE, VECTORSPLINE, LAWSPLINE and LAWSURFACE.
