Im kind of new to 3d printing.

I use 123D design for my designs. I’m facing a problem when i import an STL file in 123D design and convert the mesh to a Solid. When i do that, it says The number of facets are more and it might reduce the performance of the computer and when clicked ok the cursor keeps spinning for a while and then says couldn’t convert.

Can someone please guide me how to edit an STL.

Currently I’m trying to edit this thing(http://www.thingiverse.com/thing:922740)

Best Regards

there are several ways to do that.

Meshmixer is a free tool from Autodesk

Instep, limited free version to 3000 faces.

Did you actually noticed that the .stepfiles are also available to download?

In general, STL files are generally not meant to be edited any further and it’s difficult to treat them as anything but a mesh. Try importing the STEP file instead.

Hi Karlzhao314, StudioKubuz,

You are absolutely right. i was able to modify the step file in 123d Design.

But, in a case when i don’t have step file , how do i convert them to step file or a solid so i can edit it.

kindly give me a step by step procedure in any of the softwares you mentioned! i have not used any of it except 123d Design.

Best Regards
