designing a right angle mold

[rwithrow7XLCS]

i am designing a set of molds to form rubber around a cable and cant seem to get it to form the way the drawing requests it to be. the drawing would like the mold to form a right angle with a diagonal line like the attached picture of a mold made using conversational on an older mill. while the second picture is of what i seem to always end up with while using fusion 360. if possible could someone tell me what i am doing wrong while in modeling mode and also how i should properly machine this in cam using a parallel lace to cut out the shapes. the dimensions arent important at this time.

Here's one way to create the coupler:

ok but how would i go about designing that? i have been using the revolve function for each leg and it ends up as the second picture. also the drawing says that the first leg that makes contact with the connector should be 1.15 and the leg is supposed to be smaller so if i cant make it look like the mold from the first picture how can i make it look similar?

The forum is doing bizarre things today.  The screencast in my previous message replaced the original text.

ok i see how you made the shape but how would you go about cutting that shape from sqare stock like seen in the picture, and is there a way to do something similar while having two different diameter legs?

i answered the first part of the question myself but i still need info for the second part

Do you have a dimensioned drawing that you can attach here?

Can you File>Export and then Attach your *.f3d attempt here?

the drawing is attached in a word doc.

here is my attempt which the boss would accept but hed like it to look better if possible

The usual method of making a negative mold is to make a 3d model of the part, then use that to cut the negative shape.  For your mold, I would start by modeling the mating piece, then the part, and finally the mold adding any draft needed to release the part from the mold.

Note: The file I attached previously shows how to add the rectangular block to the mold.
