Thank you gentlemen:
I am still having difficulty understanding your technique Henry, so I will try to address them:
Here's my latest stab at it, Aram. I extruded a Spline profile of the domed portion; Which portion Henry- the X or Y profile? I am guessing the X or shorter side.converted the resulting sheet object to a Solid; filleted the edges; shelled, Aha! Filleting has been my problem from start. I can't seem to fillet a solid object with curves- only when straight lines are involved. omitting the flat face. Made a 3D Box for the flange; filleted the four vertical edges; shelled, omitting the two flat faces. Added the two objects; filleted the joint; chamfered the upper flat face of the flange to give it a slight slope; filleted the outer edge. For the groove on the bottom, I Swept a Polyline profile along a Polyline path and subtracted from the main object. The swept polyline- need more info on how that was done.Protrusions on the top are individual extrusions, emplaced manually on one quadrant of the main object and then mirror-copied; added to the main object and the edges filleted. Hmm.. okay.. most of this I think I got, but need some help here..
I also tried doing a loft from two different profiles, which sort of seemed to work, but the overall curve wasn't quite right for the top half of the door.. Henry can you post pictorial details on how you did this?
Also see the attached and tell me if it possible to bevel the sides. Tcad seems to want to do, it, but it doesn't fly after selecting all the edit points.
