segmented curves (by Byron Dawson)
I have recently be using the program with a 3d printer. I have found that the curves are actually segmented lines, which I thought was just screen rendering (no problem) but turn out to translate all the way down to a printed object. Is it possible to get this rendered as an actual curve?

You are likely using the STL format, which is the de-facto standard format for exchange of parts for 3d printing. The only geometric primitive this format can represent is a triangle.

Assuming your 3d printer software can only use the STL format, which is almost certainly true, the only recourse you have is increasing the resolution with which your model is triangulated. Go to Configuration → Chord tolerance and set it lower; then re-export. You can enable the display of triangle mesh using the text window toolbar to preview the result.

There is a link named "configuration" in the text window (the window with the title "SolveSpace - Browser"). If it is not displayed for you, try View → Show Text Window in the menu.

Thats got it.

Quick question, do you plan to continue developing this program?

I only mention it because I think you have a pretty good product here. It beats any other free program hands down and I think it takes one from beginner on up quite well. Id be willing to pay for a copy.

One thing, and it must be obvious, just not to me. If one is able to select a plane with a mouse click, why cant one select a workplane that way? Ran into a few situations where that would have been very handy.

Tnanks for the help.

What do you consider to be a "plane" vs. "workplane"? I've generally used the words interchangeably. SolveSpace has a workplane entity, but it's selectable in the usual way by left-clicking.

OK,when I mouse over a "plane" it turns yellow, I can select it and it turns red as expected. But having selected it I can not use it to as a new "workplane". It gives me a bad selection type error.

oh by mouse over a plane, I mean on an existing object that happens to have a plane as part of it, eg a cube

the cube doesn't have a plane it has a face which has enough components to define a plane.

The current implementation allows for planes to be defined by absolute primitives. I think flat faces to define a plain is for of a complication and special casing than we need to focus on.

Just my opinion, but then again I haven't been active in adding features.

thank you for the definitions, will there be any more forthcoming?

@yugami, I had a "workplane on face" feature, but it was an annoying source of bugs due to inflexibility of current savefile format, so I have reverted it for the time being. It will come back some day.
