I am training to learn Rhino by myself for an engineering company. I am having trouble when making a boat lid 3D. I can create the lid dimensions and extrude. On the bottom of the lids , there is a .25" Radius that is offset .26" from the outer sides of the lid.
I have attached a picture, and what I am describing is like the lid above the boat fish keep tank.
What is the best way to create this kind of depth inside, and should it be done using a solid exterior first, or two surfaces and joined together by a .25 radius?
However it needs to be done, please try to explain how to do this.
I would greatly appreciate your help.
Hello - I’m not sure I’ve got the right part but I think typically you’d make the larger box shape and the inset one and use a Boolean operation to combine the two, possibly followed bu FilletEdge. But, without a Rhino file, it’s hard to help. I’d take a look at these training materials, btw:
There are lots of ways you could do it the ideal “best” way would need more detailed information. Remember that lid is going to have a draft angle on it…also those parts aren’t usually injection-molded, it’ll be rotomolded or vacuum-formed, so only one of the sides of the lid actually “matters,” the other is just for rendering…unless I guess the whole lid is one rotomolded part. You should really look at as Pascal says the basic training materials.
don’t forget we have level 1 and level 2 classes via video on demand here:
Thanks for the response Pascal and Jim. It’s great to know there are folks here willing to help with knowledge about Rhino. I have been through Lynda Training and also most of the McNeel user guide. I will check out the tutorials. The company uses injection molding I believe.
I have attached a photo of the lid so it is easier to see what I am trying to describe. It feels like most everything I do in Rhino takes me forever. Maybe its because I’ve only been training about a month…
Hello - see if this clip helps at all - I just made up the dimensions etc, but you’ll get an idea perhaps.
Thank you very much for your help! This helped me out a lot. I will be back I am sure, have a lot to learn. Cheers!
