Problem with UCS

[Rog]

I started a drawing in world view in 3D which puts the 'z' axis pointing up the screen but when I change to 'Front' view and then back again 'z' is pointing in and out of the screen though the perspective of the drawing does revert to the original 3D perspective. How do I get the UCS back to the world view without starting the drawing over again? I'm using Autocad 2004. Thanks

Oops I seem to have another problem. I've drawn a solid box into a roof with the intention of cutting out the box to leave a slope in the roof. But selecting 'subtract' then selecting the roof and then the box and either right clicking or hitting Rtn only reverts to the original drawing with the box still in place. Can you help? Thanks

Not quite understanding.... can you be more specific?

Ok, I've drawn a rectangular box and then two wedges which I positioned to form the sloping roof on top of the box. I then made the wedges solid. But so as to put a slope at the rear of the roof I made a solid box with the bottom right corner of it aligned with the top left corner of the rectangle then I used 'Rotate' to angle it into the roof. Then attempted to subtract the box from the roof leaving a slope. But the box wont disappear. Phew.. This pic says more than I can. Thanks for your help.

Ah. 1st off you are doing this all wrong, not that it's a bad thing. Trust me, I've been in the same exact boat as you years ago

 

Instead of using the SUBTRACT method, just simply EXTRUDE the top of the box and use a Taper Angle of your choice, but an angle of 45 would be most appropriate. Try that and see how it goes.

 

Just a hint... Try not to use SUBTRACT unless you ABSOLUTELY have to. There are plenty of tools in the Solids Editing toolbar to get things done without constantly creating boxes and subtracting them. It takes awhile to get used to but when you do it'll be all good.

Thanks for the help StykFacE. I appreciate it. I've no doubt you are right in your approach but I was actually following a written tutorial from a book. I'm entering the instructions exacty as described but the box doesnt disappear. I can only think either my software has a bug or the book is wrong though a previous subtract example did work. Cheers StykFacE.

I agree with StykFac

 

It is not wrong. It is a longer way of doing it. Again, that is not a bad thing. that's how to learn. I would also use the extrude command but it is also important that you know how subtract works.

 

Wish I could be more help but for some reason I cant view the pic.

Thanks Rookie I'd like to know why I cant subtract in this example. It's odd you cant see the pic here it is again does this work:

 

[rookie37]

I still can't see the pic

 

I'm at work and my internet settings are probably blocking it.

 

I would play with subtract, add, and union by drawing something else first.
