Scripting / API Help / OSX version of API
« on: December 18, 2014, 10:04:38 PM »
just added. The included pre-build mmapi.so was compiled on 10.10.1, with XCode 6. I have no idea if it will work on older versions of OSX...

No worries - it's not documented! =\

(thanks for your patience!!)

can you send in an example? email to ryan. schmidt @ autodesk . com

Start the Align Tool and left-click on the planar area

Using AABox mode of the Align Tool will place your object on the ground, at the origin.

Using the Layout tool will also put your objects on the ground.

if you want to create a flat bottom, use the Plane Cut tool, then do an Align afterwards.

If you are exporting to software that expects Z-up, open the Preferences dialog, to the File tab, and click the toggle at the top.
(or go into the Print view and export an STL from there)

Bug Reports / Re: MM 2.7 crashes on loading a file (W 8.1)

Thanks for mentioning that re-connecting the network cable while the app is running causes the crash. That is very helpful!!

OK, I cannot reproduce this at all. If you have time, it would be great if you could send in a test case to ryan . schmidt @ autodesk . com, with step-by-step instructions to reproduce the problem. If you can do that, it is nearly certain that I can fix the problem...

Can you try this on 10.7?

are you sure your file contains two halves?

Anyway, you'll have to post the file for us to be able to debug...

The green arrow is basically the "worst case" direction to push on the model, to break it at the weak-point near where you clicked.

(there is a lot of interpolation & re-scaling going on under-the-hood, so this is just an indicator...)

what you are seeing is discontinuities in the geodesic distance field we use inside this tool. This artifact tends to only appear once you have sufficient mesh resolution to capture it, that is why it doesn't happen at lower resolutions. The mesh is not broken, ie there are no holes/etc, it is just very rough. Inspector will not identify that kind of thing.

One way to avoid this artifact is to use RotInvCoord mode, instead of COILS mode (the first drop-box in the parameters). However, RotInvCoord mode can have other artifacts...you would just have to experiment.

Since you are basically just transferring faces, another way to go would be to position the face part in 3D space (ie don't make it a drag-drop part), then delete the underlying area of the head model, and use the Join tool to stitch the boundaries. This will avoid any deformation of the face.

For the colors, this is a bug but one we have not fixed yet. To repair this artifact you could use the "SmoothColor" mode of the Surface Brush tool, which basically does a local color blur/blend. Disable the Refinement checkbox, and then scrub over the white area to blend in the neighbour colors.

Scripting / API Help / documentation for mm module
« on: December 10, 2014, 02:02:35 PM »
I have just added an initial HTML documentation drop, in /distrib/documentation/python_html

This is generated by Sphinx, all the manual source is in /python/doc, if you want to contribute

This manual includes all the tool name/parameter strings, I wrote some parsers (in the /doc/generated_text/ folder) to extract this from the StoredCommands.h header.

Scripting / API Help / Re: orientation
« on: December 09, 2014, 09:28:35 PM »
sorry...I'm not sure what you mean. An imported mesh? To which axis?

To rotate an object by 90 degrees around the X axis, you would do something like:

mm.begin_tool(remote, "transform")
rot_matrix = mm.make_rotX_matrix(3.14159/2)
mm.set_toolparam(remote, "rotation", rot_matrix)
mm.accept_tool(remote)

So, if you want some other alignment, you can rotate around other axes...there are more complex transform examples in https://github.com/meshmixer/mm-api/blob/master/python/examples/demo_08_transform_obj.py
