software volume management solid models

[DottorMouse]

Dear colleagues,
I've been giving satisfaction to 3d printing with a hephestos itch and since a while I have been wondering a question:
Will there be software to manage the volume of solid cad that I use for printing?
I try to explain myself: If I have to couple pieces I have the problem that prints are slightly "flat" of 1/2-tenths of mm, then I propose my models with proper game for coupling taking into account this. In some cases, on simple pieces, I could use the scale command directly from the host repetier. "but will there be software that will allow me to scale the volume proportionally?" obviously not the command scale that have the various cads because, for example, if I regret a model they "string" the pins but also tighten the holes.
do you know if there is such a software? i.e. a software that allows me to scale a solid proportionally by stringing the "males" and "enlarge" the females? in practice that I decrease / increase the volume. it can be that the moldists use something like that for the speech of the retreats.
I'm sorry about the french, bye.

I have seen that meshmixer has some function that seems to be able to do what I want, but I have not yet had the time to cuff us. is there someone who is already practical of this software?

Maybe I found the solution! the simplified3d printing software has the "dimensional adjustments" setting that does exactly what I was looking for, i.e. reproportionate the dimensions on the x axes and y. inserting a positive value increases the volume and negative vice versa! At this point I wonder: but is it not that this setting is also in care and slic3r and I have never seen it? :smile:

exactly as you say, all the software you cited have the command "scale"
:biggrin:

And no, I'm sorry, it's not the same. the scale command besides the slicing programs have also all cad. the "dimensional adjustments" does a different thing, with a negative value decreases the section, i.e. reduce the external dimensions and increase the internal dimensions and with a positive value vice versa. It's just what it takes in the common case that the printed pieces are a little "flat". acting only on the x-y plane I assume that it practically does an offset of the internal/external profiles. So if geometry is a little complex with tilted machining I don't know what results you can have, but it's already something. :smile:
