I am in 2001, so WF Shell may have more features. You cannot shell certain a certain area. There are no options for stopping the proliferation of the shell such as a stop plane or remove surfaces or only apply to chosen surfaces. I wish such options existed. Looks like your only option is to cut away the material.
Select the parting surface or plane as draft hinge and then right click and click on "split by split option". With this you have option to draft independently both sides of draft hinge. So you don't draft the other side.
The Shell feature can be a pain. I see it Shelling out under the protusion to the right. You may just want to Cut the surface since there are few features to deal with. Dim the cut to the outside walls to easly control your wall thickness. Hope this helps.
I don't know how long you have been working with Pro but Iwill give you a bit of unsolicited advice from a long, long time Pro user. Avoid using the Shell command unless someone has a gun to your head. The good part is...it's fast and it's easy. The bad part is...it's fast and it's easy. If I were on a witness stand andan attorney asked me what was the most evil command in the Pro/E world, I would answer The Shell. In fifteen years I have had more trouble rerouting, redefining and dealing with shells buried at feature 5, 6 or 7 of 1000 than ANY OTHER FEATURE hands down. Imaginethe difficulty you are having with your model multiplied by an order of magnitude or greater.The Shell istruly evil, my friend. I have rarely in my experience, I can count on one hand, ever agreed with the Shell in it usage in a part. It is a very specific command with specific uses,not a general one as many think it is. Users utilize it way too often and too casually.
Unfortunitly, I need to use it with my plastic designs. I have learned to use the investigate tool to figure why it won't shell. Lot of problems come from rounds, I try to leave them after I shell,or cuts made on the opposite side from the surface you are shelling. For example, if you make a block cut a pocket out you need to make sure there is room for the 2 wall thickness ( pocket wall and outer wall) to be created by the shell. Once you get a feel for it's limitationsis not too bad.
No flames here dl, I just had to hammer thru the shell to get to the nut
Is this the type of shell you want? (see image) If so, shell, like you want to -removing the tops of both volumes, then add a protrusion back under the center wall using edges of the wall that had been cut away. This way you have no dimensions to worry about (the shell drives all walls.) Let me know what you think.
View attachment 517The shell allows you to set multiple offsets. So each wall can have a different thickness. IF you want to you can set the shell distance to match the width of the protrusion on the right, leaving what you want.
NOTICE THE BIG IF...
This may have unwanted consequences later....but in a pinch.....
well that is the sort of part i am making but it has 3 more posts on the right side.that was my first move to get around thisso i just selected the surface and changed the thickness but pro/e didnt like thatbecause there are some more features on the right
i think the shell command has to evolve so you can actually use it inengineering modelling, i think everybody know that even the simpliest thing has a lot of features whenis to be injection moulded
