Questions & Troubleshooting / Not working in windows 10
« Last post by cajunctionAI on May 19, 2017, 05:53:21 PM »
I had mm working in windows 7 by just choosing 'basic' driver in prefs.

Here in windows 10 where I upgraded to, its no longer even running, just crashes after I say 'yes' to allow it to  take info.

I've got same drivers I had in windows 7 where it didn't crash,so whats up in10 ?

I'm temporarily using laptop, hence the question.

Think with BooleanDifference you're on the right track.
Performing BooleanDifference (A-B) creates an object where resulting surfaces' faces are grouped based on the source objects.
Do  BooleanDifference A (liver object) - B (artery object) = A1. Now do BooleanDfference A1 - C (vein object) = A2.
Now with A2 active go to SELECT and select some part of the former A object. Hit G to expand the selection to the group coming from the A surface.
Hit I to invert the selection and hit X to discard all surfaces coming from the B or C object....
This results in a single shell with open boundaries.

On your A object SELECTall (Ctrl+A)
On this selection run Edit/Offset. Set a positive offset (the thickness you want to print the mold). This flips the inside surface's normals and creates a second outer shell around (some solid/watertight but hollow object). Subtract vein and artery object now...

Questions & Troubleshooting / Re: Meshmixer 3.2.37 not running

I have loaded and imported models OK now but after a period whilst generating supports, during sampling ground plane the program stalls part way through and reports 'MM application file has stopped working' and the the program closes.
Can anyone help with this problem please? If you need further information please ask.
I have a HP dv9700 with nvidia go 7150/630M combo,  or  but for somethings it gets job done OK.
I fixed by choosing' basic driver' in prefs which I presume means gpu combo too slow for main mode or something ? Y

The title might be confusing so I'll try to explain what I want to do. I created a 3D model of the liver, its artery and its vein (portal vein). They are 3 separate objects. I am going to print the artery and the vein as a single object (I have joined them with a tube like structure so they can preserve their spatial relationship). Then I am going to cut the liver model using plane cut in 4 pieces and  print these as hollow models (%0 infill). These pieces will serve as molds for transparent silicone or ballistic gel, so I'll end up with a transparent liver model. However, just before pouring the silicone or gel, I want to insert the artery and the vein inside the molds, so that they will be included in the transparent model. The problem here is to be able to create the holes where the artery and vein penetrate the liver. I can do a boolean substraction from the liver model and it creates these holes where I want them but it also creates a very complex tubular system inside the model, as the arteries and veins inside the liver are also substracted. Is there a way to delete these tubular structures, so that I only have the liver model with just the holes on the surface? Is there a better way to create these holes instead of using boolean operations?

Questions & Troubleshooting / Re: Runs in windows 7 but all black 3d work area

I'm running Win7 64-bit with no issues.  Maybe the problem is out of date video drivers?  In the requirements for Meshmixer 3.2 it does state "NOTE: requires graphics card drivers update".  So maybe check into that on your system.

using windows 7 atm, is this the cause ?

I get no 3d anything showing up, even bunny..on load of bunny, stil all black.
Thoughts ?

Questions & Troubleshooting / Re: Export multiple objects and print setup changes

Thanks magweb, this feature was super useful for exporting to print on multi-material printers such as the Objet Connex of which we do alot. Shame it's gone as I used it teaching in a design course and it allows students to have numerous parts that output aligned and organised. I'll ask some around about writing a script to export a combined file as this is way out of my league. otherwise MM remains a fine tool for working with stls. Cheers

many thanks for your further a help. I worked through your suggestions/questions one by one and nothing made any difference, that is until I changed to Basic rendering and restarted. On importing a model MM went through 'computing' etc. but this time displayed a grid plus the model. A quick analysis, overhangs, supports and it seems to work fine.
I will obviously test it further, but note it has crashed and closed a couple of times whilst I have been typing this response.
The graphics are those built in to my laptop, Mobile Intel(R) 4 Series Express Chipset Family. I frequently check for any updated drivers.
Questions & Troubleshooting / Crash 100% of the time on 10 mil poly models
« Last post by eobet on May 12, 2017, 05:27:18 AM »
We have a number of 10+ million poly STL files which we are trying to find an application that can manage to add thickness to (offsetting into the model).

The models are of boats currently in production, scaled down to 10% to become about 700mm x 200 mm x 100 mm and we want to add 1.5mm wall thickness to this. We're not trying to apply thickness to an entire assembly, but rather we import each part separately (hull alone is still 10 million polys).

However, all of these files crash Meshmixer 100% of the time.

Are there any logs output anywhere that one could send to the developers as a bug report (and does anyone know how to reach the developers)?

We cannot share the files as they are confidential.

(We have tried both 3D Studio Max and Blender, but they add "spikes" poking through from the inside out of the models which didn't look good. Zbrush was able to add thickness, but it took a lot of work, possibly removing detail from the outside surface as well, and we only have one license for that package anyway. We also have an old Netfabb license, and it adds thickness nicely, but sadly always closes the models and ours are all exported from surface CAD data, not solids so that looks weird still.)
