Beta / Re: beta 3.2.487
« on: September 22, 2017, 11:11:44 AM »
For macOS users:

Note:
As on WIN the keys to contract/expand selection are SHIFT+"," and SHIFT+"." now. (NOT as in former versions "<" and ">")

If there are issues doing the Booleans:

Sorry I did not mention that you need to rise Density in Remesh on the different parts to get a denser meshes.

Questions & Troubleshooting / Re: Creating Slices in Meshmixer 3.2?
« on: September 20, 2017, 05:26:56 AM »
Sorry, MakeSlices is broken and disabled since 3.1.... (since beta 3.1.106).

The only alternative is PlaneCut with CutType Slice(KeepBoth) and enabling snapping in the widget.

Questions & Troubleshooting / Re: Align the support's orientation

There was an implemented 3D printing preset "DMLS Tool Steel Preset" in the Overhangs Tool of MM's beta 3.1.88 (http://meshmixerforum.com/index.php?topic=2928.0) which did more perpendicular supports aligned in rows. Unfortunately this beta isn't available any more and this preset was dropped in later versions.

I understand your need to get supports robust against the traction of a DLP printer. Are you aware that you can add supports to the auto-generated supports manually as soon as you generated supports? - Even supports for supports.... This way you can make the structure much more stable.

Sorry, forgot this....but you'll get nice images now ;)

Your STL comes with a slight error which makes it hard to get nice results. At its edges top/side and top/bottom are tiny faces with normals disturbing a smooth surface(image 1.1). For they are small you can get rid of them selecting all and running Edit/Reduce. A slight reduction is enough (image 1.2).
EDIT/GenerateFaceGroups will now create a single group on the side and the bottom. To join the groups at the top select the side plus the bottom group and in vert this selection. Run Modify/CreateFaceGroup to join this selection to a single group.
Select the side group (> 1.3) and run Edit/Extract with an Offset of 2mm (> 1.4). Separate this offset shell via Edit/Separate (> 2.1: red).
Select the top group  and run Edit/Extract with an Offset of 2mm too. Separate this offset shell via Edit/Separate (> 2.1: yellow).

Now SelectAll of the yellow top object and run Edit/Extrude at minus 3 mm (it's offset is 2mm > gives 1 mm intersection) in Direction "Normal (>2.2).
Run EDIT/GenerateFaceGroups to get a group at the extrusion's side. Select this group and using Edit/Transform scale it up along X and Y dragging the square handles (> 2.3)

Duplicate the yellow and blue objects. Run BooleanIntersection on one pair and with the blue being activated at first BooleanDifference on the second pair.

Now SelectAll of the red side shell and run EditExtrude at minus 4 (its offset is 2mm > gives 2mm intersection) in Direction "Normal" (> 2.4).
Run EDIT/GenerateFaceGroups to get a group at the extrusion's sides again. Select the lower side's group and transform or extrude (> 3.1).

Duplicate the rest of the blue and the red object. Run BooleanIntersection on one pair and with the blue being activated at first BooleanDifference on the second pair.

Questions & Troubleshooting / Re: Using an IMac

In menu:Help you'll find a pdf "KeyboardShortcuts" listing the keys you've to press while dragging the mouse (with pressed LMB or RMB - depends on the set Navigation Mode)

Setting up a printer is a bit complicated in MM 3.2. You'll need to manually copy and edit a template file ("custom_printers.xml") you'll find in Documents/Meshmixer/printers.... (setting a printer via MM's preferences does not work in this version)
Or you'll try the current beta 3.2.487 where you can set up a printer via MM's Preferences dialog as shown here:
http://www.mmmanual.com/printing/
You may get this beta here:http://download.autodesk.com/us/support/report_a_bug.html?SelProduct=Meshmixer

Yep, got it.
Gonna look into it this evening...

If this refers to MM Beta 3.2.487:

Please report issues using Feedback/ReportABug in MM's menu bar.
This links you to an online form to provide the needed informations....

Are you on MM 3.2? On WIN or MAC ?

Did you try to disable Analytics and CheckForUpdates in menu: AboutMeshmixer ?

Questions & Troubleshooting / Re: Smoothing/tangent mesh
« on: September 12, 2017, 07:15:53 AM »
If you switch on wireframe rendering (hotkey "w") you'll see that owns a minimal density.

You'll need to subdivide it to get more vertices to move them in the Smooth tool.

SELECT: SelectAll > Edit/Remesh at LinearSubdivision  - mode. Pull the density to max and accept.
You'll need to run that subdivision several times to get a nice Smooth result.

Sure,

load it to some file server and send me the link via PM

If you did several scans of one body and you load them to one scene: Most likely they do not fit to each other.
So the first step is to get them to fit, "aligning" them. Meshmixer doesn't have any tool to do a mesh comparing alignment automatically. Here you need to Transform http://www.mmmanual.com/transform/ the parts manually (If you're looking for some freeware you might use Meshlab and its "A" = "Align" - tool which does points-pair registration).
After you managed to place the partial scans right you might Combine all partial scans to one object and run EDIT/MakeSolid in MM http://www.mmmanual.com/make-solid/.
If you miss details in this MakeSolid result use your combined scanning result as a target and SCULPT/AttractBrush to suck the Solid to the source.

Could be done in MM but might be easier if you do it in your CAD app where you built that insole.

In MM you need to define Face Groups of the surfaces for part 1 and 2. You might do this (what's best depends on your mesh's triangle structure) via EDIT/GenerateFaceGroups (see:http://www.mmmanual.com/generate-face-groups/) or manually via a selection in SELECT/Modify/CreateFaceGroup.

Now, if there's a consistent FaceGroup for the footprint (part 2) you can use EDIT/GenerateComplex. DoubleClicking this part2-surface will create an complex inlay of this surface. You can define its depth clicking on the inlay's seam and setting the desired depth (2mm) in the tool's flyout "OffsetDistance"... (see: http://www.mmmanual.com/complex-tools/)

Don't think the Complex tool will work for your part 1. So you'll have to go the Boolean way. To get the right result needs extractions/extrusions of the outer almost "vertical" surfaces to construct a subtrahend object.......
(could you post the file or send me a link?... might be much easier to explain....)
