Help with simple calculator modelling

[nweston]

Hi I'm relatively new to creo and i've just started doing my solo first project, which involves modelling a calculator. I'm curently attempting to model the back casing http://imgur.com/fvkQ8ul&fWTVPjV#0 http://imgur.com/fvkQ8ul&fWTVPjV#1 as a seperate part and this is what I've got so far. http://imgur.com/VLIberf

My query is regarding how you would go about modelling the slight extrustion that blends into the battery casing. It gets larger vertically as well as widening horizontally. Also the curved bottom end to the extrusion coresponds to the existing curves on the main part, is there an easy way to make it do that?

Any criticisms on what I've done so far is also welcome, I'm just kind of winging it.

Hello Nathan and welcome to the forum.

This is a relatively simple part. I would probably do profile sweeps from the side and trimming sweeps from the backside. Treat is as two separate processes... 1st the primary curved section: sweep the profile and trim the shape from the back; 2nd sweep the profile of the "rim" or "lip" and trim it as well. 3rd... finish it up with some stylish rounds (C2 rounds are often used in these applications).

you can post the images here in the forum although you might scale them a bit

And don't forget to consider drafting the surfaces...

Sorry if this seems dense but could you possibly explain or give me an example of what you mean by doing profile sweeps? I've been looking around and most of the videos I find are videos of people using the sweep tool to make cylindrical pipes/ridges.

My mistake, Nathan. I was using the "profile sweep" as a generic term. I meant to use an extrude feature.

I love when people look at plastic parts as "simple"

Attached is a Creo 2.0 model of a similar design you are asking for. Of course, parts like this get extemely involved. Every feature has a small deviation depending on how it is created. When working with plastics that require draft angles, you quickly move from 3D to "12D".

Have a look at the file if you can and you should get an idea of how I arrived at this.
