3d Help!?!?

[ReMark]

I really don't understand what the problem is but let's give it one more try shall we?

 

Start over and follow the steps/instructions exactly as indicated.

 

1) Using the rectangle command create a large box.

2) Using the offset command create a smaller box inside the larger box.

3) Start the region command. AutoCAD will prompt you to "Select objects". Select both boxes. Press the Enter key. AutoCAD will respond "2 loops extracted" and "2 Regions created.

4) Use the Solids Editing command called Subtract.

5) AutoCAD will prompt you to "Select solids, surfaces, and regions to subtract from .."

Pick the outermost box.

6) Press the Enter key.

7) AutoCAD will prompt you to "Select solids, surfaces, and regions to subtract .." Pick the inner most box.

 

At this point both boxes should be treated as ONE entity as far as AutoCAD is concerned.

 

Visually you'll see no difference. Just two flat boxes.

 

Use the List command and when prompted pick anywhere on either of the two boxes. The text window contents should confirm the fact that we do indeed have a Region. If it doesn't you did something WRONG. Start over again! If it does confirm it then move to the next step.

9) Use the Extrude command and specify any height you want.

 

I normally switch to my 3D modeling workspace and use a SE Isometric view so I can see the results immediately.

 

Now you try.

I trust you will have been successful following the above instructions. Unfortunately I must take my leave now. I will check this thread tomorrow morning upon arriving at work. I'm expecting you to say you achieved positive results. Do not disappoint me. Good luck and, for me anyway, good night.

lol i believe i have succeeded......i did the exact same as last time but it worked??? i will post it up for you to check

 

ALSO.....what process do i now do to create a window door etc that i can successfully assign materials too??

 

thanks once again

trial box.dwgFetching info...

It's important to note that in ReMark's steps, the drawing will be entirely in 2d, until step #9..

 

(He says "box" a lot in those instructions, but is referring to a 2d rectangle drawn with the Rectangle command, not to be confused with the 3d Box command)

 

A box is a solid 3d object.. if you created your building with that, or only extruded the outer rectangle (or closed pline), you'd have a solid mass inside the outside shape.

 

The region, and subtract commands were used while the rectangle was still a 2d shape.. this changed the rectangle to a "hollow" rectangle.. Through the subtract command, the inside rectangle was used to cut a shape out of the outer rectangle.

 

That way when you extrude the shape, you are only extruding "walls" of the desired thickness.

[MikeScott]

Hey.. if you attach the drawing in 2006 version ("save as") I'll walk you through some more if you want.

[MikeScott]

1- Put your view mode into 3d wireframe, and get to a 3d view (like SW or something, but it's important that your UCS stays the same.).

 

2- Draw a rectangle that will be your window opening. Make sure it overlaps the wall thickness of that box you made with ReMark, and make it as wide as you want the window opening to be.

 

3- Next extrude that rectangle the overall height of the window opening (don't region it this time).

 

4- Then move it upwards whatever distance from the floor that you want the windowsill to be at. ( you can use the move command, and enter "0,0,0" as the start point and "0,0,whatever as the height you want the sill to be".. or use the elev command, or change the elevation in the properties window for the box)

 

(You gotta be SURE about your position at this point.. once you "subtract" the box from the wall, the box will disappear, and relocating/moving the hole isn't something I can easily instruct you on. If you want a series of window openings, I suggest you save a copy of the box off to one side so you can reuse it.)

 

5- Subtract it from the overlapping wall, and you'll have a window opening.

 

Worry about the glass and frame with ReMark when he get's back, since I don't have 2010 and there's new features that might make that a lot easier to do.

 

But now YOU tell ME how you're going to do the doorway.

Semantics again Mike? Yes, the references to outer box and inner box probably should have said outer rectangle and inner rectangle. Hey, I got up at 3 a.m. cut me some slack!

 

pbooth11: I'm thrilled to hear you finally got the Region command to work. It is however but one way to accomplish the task of constructing a wall. There's probably three other ways to do it.

 

When it comes to creating openings for windows I like to reorient my UCS such that X is to the right, Y is pointing towards the top of the screen and Z is coming out towards me. I draw the outline for the opening using a polyline then I either extrude using a negative value (then subtract this solid from the wall) or I use press/pull to punch through the wall. Again, there are many ways to accomplish the same task. It all depends on your approach to the problem and what you have been taught or learned along the way.

 

As far as assigning materials goes I think you need to first take care of properly constructing your building. I hope you have given some thought to what Mike and I have said about assigning materials to a layer rather than to individual objects.

Naw.. I was bored and thought I'd give him some "whys" in case he was skipping steps or doing stuff a slightly different way.. but he had it before I hit "post," (I went and ate dinner before posting) so yours was fine without mine.

[pbooth11]

thanks you 2 for advice.......i will try to create a window using your processes and will post up the reults later this afternoon

 

once again thanks
