How to merge parts so that the outlines disappear

amanda_chan073

I am new to Onshape and I am making a torch body for my school assignment, however I can't really figure out how I will make my torch body, which looks like this.
But I've decided to make different parts for the torch body and then merge it together, and also make the bump at the bottom separately. However I'm not sure if it will work and I've started the very first bit but don't know how to merge the parts together so the outlines of the parts put together is not visible.

Please help as this is very urgent....Thank you.

There are a number of approaches... you can make profiles along the way and loft or you can loft from your circular front to a point and then user guide curves to control the shape..  Here is a quick example of an approach.  Modifications might be necessary to make ti hollow like making it go to a small circle instead of a point..

If you mean the vertical edge in the middle of your picture, you can't remove it in the Onshape view.  The CAD needs to know where different surfaces start and end, so those lines will always be rendered.

What you can do to make sure they don't appear in your final print/render/etc is to fillet any edges so that they're smooth transitions, like so:


In this case though, I'd look into lofting the body of your torch, as in this example:

Basically define cross sections at two or more locations, along with guide curves to define how the loft looks between those profiles.  You can also, if you've done a paper sketch you like, import a picture of that paper sketch into an Onshape sketch to help trace the shape with splines.
