working with your mesh models without decreasing detail !

[Anonymous]

Last time I looked at bring in mesh models that where high detail , I only found info on droping the polly count to match what fusion can handel . But if you use another program to split the mesh into pices and then load to fusion you can use mesh to brep with out loss of detail.

That's a great idea Tony.  A while back I tested the slicing function of Meshmixer (I don't believe it has anything to do with 3d printer slicing), which made clean edged slices of a mesh model, and then after importing and converting to Brep used Fusion's Move point to point function to get perfect alignment again. 

Another person was able in other software to export the meshes of various smaller objects individually, which is another option I guess if possible.  He noticed though when I think getting past say 50,000 or 100,000 sum total faces, very diminished performance, so something to keep in mind. 

It's definitely more work to import a very detailed mesh in pieces, but is definitely interesting what the few people who have tried it are capable of doing with Fusion and its CAM.

I noticed though with Meshmixer, setting the total faces to 10,000, was able to achieve maintaining impressive detail, with apparently a very good optimization algorithm, so good to see first what Meshmixer and 10,000 faces gives you in terms of detail.

Ok all you need to do as Boolean split the model and save the file not each pice to a file . When importanted the parts are ware they should be . Then use the mesh to b-rep , I am not sure the max block you can select but if the block is under the max poly count it will work . It is not purfect but usable . I am out so I can post pics but I will !

ok so here are some pics

Hmm, so are you talking about using Meshmixer to "Boolean split the model and save the file"?  I don't see any function in Meshmixer specifically called Boolean split though. 

Looks like amazing pictures.  Is that Fusion 360 that the CAM simulation is in?  I can't see real well in the picture, but from what I can see looks amazing.  What material is that BTW?  Imitation ivory or something? 😉

Hi Jesse 

I have seen posts saying you can use meshmixer and a few other programs to split a mesh , I used rhino . I don't know what you feel conformable using , there was a post about netfabb but I can't get there webpage to load . I had found rhino worked so I stopped looking for software geared to the 3d printing world . I think you want a 1/4 " square

ps model was simed in cam and rendered . the stock is one of the new genstone I didn't combind the bodies so the texture is blocked to the body and not the whole model . 

yes It is hard to see . I will try and get a better pic . I am playing with a image to surface script  and waiting for that to get done so this may take a bit . 

this may help

OK, cool.

the texture is jade (white- green)

Very cool, I originally thought that picture was a physically machined piece!  So is this and the CAM simulation in Fusion 360?

This is the top of it !

Wow, that looks superb!! 

Can I ask what size your finishing end mill is?  What kind of wood is that?  And what CAM operation did you choose to give such nice finish?

Thanks again for sharing your impressive work!  Go Fusion users!

i used a parrell pas and a 1/8 endmill . the wood is local maple (new england)

thank you

Tony, if you get a chance I have a few more questions for you 🙂  First, I was wondering if you can share where you get 3d relief meshes like the one you used here?  Also, regarding the image to surface script you mentioned, is that available (free or paid) to use?

Thanks,

Jesse

@Anonymous it`s here bro https://github.com/hanskellner/Fusion360Image2Surface

it`s like all the other addon`s hiding in github or the api section of this forum there is quite a few there, that are quite usefull I keep asking for them to sort it out but they dont

Hi Jesse I got that model from http://www.3dmodelclub.com/cmsj15/ and it is payed . I got that model into fusion , cut the bottom out and milled in a descent time . but scaling it and moving it to a different file is a pain . I went to brake the link and 8 hr later it is only 61% done so that work flow will have to change . so that is a taste of what you will run into with a model like that . it is a good test of what either cad or cam software can do . feel free to ask more questions .

That looks like a great source to get 3d reliefs.  I was curious if you happened to know roughly what the total number, all together, of faces, or polygons as you say, were for the mesh you converted to Breps?  That way wen I try something like this, I might try to reduce that number some so something like scaling, or even modification, does not take too too long. 

Thanks again,

Jesse

I can pm that info later , the point of the test was to take a model that is and has been a pain in my back side to work with . To get fusion to convert it to a machine able model . I will be stripping it to get it smaller in size . An igs file is over 1.3 gb yes gigabytes! No typeo that says something about why stuff like this is in a mesh format not a solid .
