Sheet Metal: Drip Tray with complex sloped floor

[Denis_B]

Hi all,

 

I need your help please, to model up a "drip tray" like the one attached, but I need to do it in Inventor Sheet Metal so that I can obtain the flat pattern for laser cutting the material, which is 3mm Stainless Steel.

 

I have done ones that slope to one corner but this one is slightly more complicated, and nothing I try works for me!

 

The below is just an example of the shape, this is modelled form a solid block, which I just cut away the slopes & shelled it out to 3mm thickness.

It has 3 slopes on the floor, so that the tray drains to the center at the front. The front plate will be welded on after as at is not possible to fold it as one piece anyway.

 

My efforts involved creating each sloped section of the floor individually (using planes, sketches and faces), and trying to "flange" the vertical sides and then trying to join these up using the bend tool, but it just never works for me. The corners are probably just too complicates with all the different slopes and angles!

 

Any help will be greatly appreciated, and thanks in advance for any help or advice on this.

 

The bottom picture is the desired shape I am looking for as a flat pattern, I have attached a STEP file also Bottom Drip Tray 1460x650x3mm_ST.stp.stpz
