age .pdo and .objs

[Teopado89]

Bye to all,
I'm about to get home with the 3d printer, and not miss a second, I've come forward looking for models to print on the internet.
I was looking for models to make cosplays, and I see very frequently that extensions are .pdo and .obj.

for those who did not know the .pdo are files that open only, it turns out, with pepakura and therefore not with the paid version (I asked the manufacturer) it is possible to export solid models.
then I folded over the .obj, but the only way I found to manage them is this:
import them into freecad
create a mesh in freecad
export the mesh in step and then open it with other calculation programs (cat use that is what I know best).

the problem that the cat mesh turns into a huge set of surfaces to manage, all disconnected. to make a good 3d printing I must have a solid closed.
Do you know any way that starting from a .obj file I return a solid file in .stp?
or still a way to speed up the process?

Thank you.
Matteo

Hi.
you can try importing your .obj with blender and editing it there by saving it directly as stl, obj. However, I recommend you to "resume" it first with programs like netfabb or slic3r (under the file menu you can find the option).

Hello teopado,
Can you explain to me how you are currently turning the obj into stp into freecad?
I know instep but it's paid. there is a free version but it turns you solid rather simple.
also presents the same problem. the step then is however formed by many triangles. therefore a flat surface is however formed by many triangles. .
the step exports it to you but it is not ideal.
