Parametric modeling- clam shell containers

[Anonymous]

I'm wanting to model something like the item below. However I'm hoping to do more than just one of them, each to have the ability to hold a certain amount.. ie 16oz / 24oz. If it were just one or two I'd model them straight up, but if I want to do more than 3 different sizes I don't want to have to do that. I assume parametric modeling is the answer here. Trouble is, when I've tried creating parameters they tend to go 'wonky' after more design features are added. I'm looking for a little guidance here. Be it in the form of a f360 file that has similar parametric that I can attempt to replicate, etc..

Thanks for your time and any help you may be able to give.

Hi,

please share your basic design.

See .f3d attached... thanks!

1. Sketches need to be fully constrained and dimensioned for a parametric design to work reliably. In the browser, a fully constrained sketch will get a red lock symbol added to the sketch symbol. Depending on the environment e.g. Infinity Pool all sketch elements will turn black.

2. If a fillet can be easily applied o the edge of a solid or surface model it should not be part of a sketch. This applies to all of the fillets in your design.

3. There is no reason to use an offset in the sketch for this particular model. Revolve as a surface and then thicken, or revolve as a full solid and then shell.

Point #2 and 3 will simplify the sketch so drastically, that fully constraining and dimensioning it (point #1) will in fact be a lot less work and it also creates faster and more reliable models

Thank you! I will give it a shot and report back. That makes a lot of sense.

I was able to succesfully constrain the entire assembly to each other to achieve what I wanted. Thanks!
