Subtraction problem

[Berzerker]

Ok at 2D but I consider myself a rookie even though I've played around with AutoCad since the 90's. I try to dabble in 3D every now and then to learn.

I wanted to bevel the edges of a cover for 3D printing and when the last piece of the shape I want to subtract from the object is placed and I hit enter, the whole thing disappears. I go back making sure to pay attention as to what I want subtracted from what. All the other pieces subtracted just fine ... it's just the last piece.

I've been told to get fusion but I'm not a student and no I won't spend that kind of money for something I do as a hobby.

I am not sure what you're asking, are you trying to chamfer the edges or fillet?

 

Can you post the .dwg?

[Berzerker]

I use the fillet command. it's all I know how to use. In the left lower corner, you can see where I made the shape to subtract from the cover.  I've tried to union them together and then subtract and I've tried it as separate pieces. In the first picture the shape I want subtracted is sitting off the part to show it is a separate object and isn't in place.

When I place it in place and hit enter cover and all that was selected disappears.

More so on the union and subtraction side of things is my problem.

[Berzerker]

Select object to subtract from: I select the cover

Select objects to subtract: I select the shape

I hit enter: everything disappears, cover and all

Do you want to chamfer the edge or fillet the edge?  Chamfer = beveled.  Fillet = rounded.

[Berzerker]

Fillet

But maybe I'm missing something here? I made a shape of a rounded fillet and want to subtract the shape from the square corner of the cover to make it rounded.

shape to be subtracted looks like this.

Corner shape

[Berzerker]

Here is the corner shape copied and put where I want to subtract. It's just the last corner. As you see all the other edges are rounded ... no problem. I only like about five corners left and I can print.

[Berzerker]

I think I found my problem. Undoubtedly, I was off just a few ten thousand and somehow, it's now confused. Pay attention to thethree-line fillet and the five line fillet.

You should have been able to FILLET the edge without creating any shapes.

[Berzerker]

I never had someone to teach me AutoCad. I taught myself. Yes, I'm probably doing things the hard way or the wrong way ... you pick but it's all I know. Most tutorials I've seen show the union and subtract ways of shaping solids. I'll look into chamfer and fillet more. Until then I can just union the corners back on (I've already saved and exited the program so I can't undo.

2007 doesn't have a filletedge command , only chamfer and fillet.

And that's why God created the Internet and search engines.  "In AutoCAD 2007, the Fillet command can be used in 3D to create rounded edges on 3D solids. To use it, you need to select the "Fillet Edge" option from the Solid Editing panel. You will then select the edges of the solid you want to fillet and specify the radius. Ensure that the objects you are filleting are at the same elevation."

If you would just post the drawing, you could be directed how to do it.

 

Fillet works on 3D just fine. This is AutoCAD 2000i.

 

Command: f
FILLET
Current settings: Mode = TRIM, Radius = 0.5000
Select first object or [Polyline/Radius/Trim]:
Enter fillet radius <0.5000>:

Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]:
Select an edge or [Chain/Radius]: c

Select an edge chain or [Edge/Radius]:

12 edge(s) selected for fillet.

And God gave me eyes to go look after I read about them on the internet. and deduce 2007 doesn't have filletedge.

Sorry SLW210, that was a little short on you. But I already checked. The internet is the one that has videos of only union and subtract online with 2007.

I have moved your thread to the AutoCAD 3D Modelling & Rendering Forum where it belongs, please post in the correct forum.

 

Did you try the Fillet command? 

 

I'm never said one thing about FilletEdge, I also asked for a .dwg.
