Hi, i am trying to use the solid map feature to create a 3d mesh but there is an error that keeps showing up 'non-mappable(2):along-faces form 3 loops. need 9'. I have googled but have not found answers to my issue. I dont know what else to do appreciate any help.

I will attach my .hm file

Thank you

    hi,

     

    not sure if you are familiar to HM hex meshing.

    I suggest you to take a look at this video as a reference.

     

    You basically need to slice your solid in small mappable regions to get a full hex mesh.

    You need to activate the 'mappable' visualization, and slide your solid until you get all the solids green or yellow..

    Hey again i have watched that video and other one similar and one thing that i cant understand is where to split my piece (the ones in the videos are always obvious) and when i do slice my piece in some place and proceed to create a 2d mesh when i try to create the solid map i get the same error with different numbers, even when i work on tiny segments of the part, idk if that helps or not but i tried bigger and smaller segments and i get the same error. ex: 'non-mappable(2):along-faces form 0 loops. need 1' or 'non-mappable(2):along-faces form 1 loops. need 2'. I dont know where these values come from... On the videos its always nice parts /:

    Thank you

    @Janeiro: for your model, you can begin with 2D mesh (see my picture) and then build 3D mesh by 'drag'. It's so simple!

    Hey I tried to drag but what i got was not a mesh of the whole solid :/

    How do I mesh the whole solid with the 2d mesh i original have created? (i know theres a way cause others have done it)

    Am using drag the wrong way?

    Thanks

    Have a look at 2D mesh within '^Surf_1'  & '^Surf_2' and you will understand:
