Creating the Door Handles

To create this door handle, start with a box (which will be the base of the door handle) then bevel it inwards a bit and then add a cylinder the centre of the base. The create a box, and give it 4 segments going across the width of the box and move those segments up a small but to create a small curve then add a chamfer modifier to round off the edges a little bit then add a turbosmooth and place it on the cylinder to create the door handle as seen in the image below.

The image below is the door handle I made for my bifolding and sliding doors. to create this I started off with a box and added segments and used those vertices to give it the rounded shape and chamfered the edges as well as use turbosmooth. The base and the actual handle were made from 2 separate objects. The two images on the right were my reference images for this door handle.
