It kind of looks like you were working on modeling the solid parts as a 1/6 part to replicate around, instead of maybe focusing more on just modeling the holes and then cutting with them?

In some more complex cases that can be good to model the solid pieces as a 1/6 part, but if it is possible to have a single larger piece that then gets cut up that tends to be quicker.

Thank you so much Michael !!..I did almost it!! after million tries .. ok now I know that is a best approach... I did a mistake.. I did the boolean dif.. with some curved line from the first crazy revolve.. sometimes it didnt work..I dunno if boolean dif with curved lines is a problem..
I had a big problem with secondary nested layer of spokes.. I will try this way.. I did with cuted spokes of the first, and I found out very hard to do a boolean.. and for the end.. very hard to do the fillets.
I will try it way with a secondary layer of spokes from the first and then the fillets.. I will come back later with success or fail =).

Oh ! you are so fast.. i did my post and not saw the last 1.. I will try now.. There is no price your help.. with it noob wheel i am learning a lot!!

Hi Tharso, yeah you cannot normally do a boolean difference with a curve that is going around in 3D space, it must be planar.

So you usually want to try and work with drawing 2D curves more often. They will become 3D in the end when they get automatically extruded and projected, but it is a lot easier to let the booleans and intersections produce the 3D curves rather than trying to draw fully 3D ones yourself, when possible.

So if you shape has some well defined profiles of it, try to work more on drawing 2D profile curves to describe them, and then build shapes from some of them, and use others to cut with.


For the secondary layer of spokes, try to imagine what they would look like if they were existing all by themselves, they would look something similar to the first layer, just with a different pattern, like the holes will be different shaped and be rotated a half step or something from the original one.

Model them like that first, as if they were a shape all by themselves, and then you can work on combining them in with the other part.


If you run into difficulties, try to post your current model that you're working on - 3DM format is actually the best format to save it in while you are in the middle of working on it, only use .STP format if you need to export to a different CAD system.

I did 1/4 solid part.. but no success when I tried Boolean ... I did only without the secondary part joined with boolean .. when all merged with no fillets I could not do the booleans..

sry my english

Perfect, I will try now.

ok sry..next time I go to Moi before send the file... I save my work in 3dm always.. but MoI to viacad and vice versa the best for me is step..thats why I sent step file.. I discovered viacad in one post that u did.. and I use it for some bruteforce booleans and fillets.. it help noobs do thinks when cant get the right way I think.

Thanks,

Tharso

Hi Tharso, no problem - I just wasn't sure if you were saving it in .stp for your regular work while inside of MoI.
