Newbie at 3d so how do you start.
« on: May 12, 2005, 01:27:03 PM »
I just want to play around a bit.  I'd like to know the best way to make a one room single floor house with one window and one door.  What do I start out with for this?  Layers?  Extrusion of a what?  Do I have to reset my ucs?  Pretend I don't know squat diddly about 3d. Oh yeah I'd like to be able to do that section cut thingy with pretty good detail.

layers layers layers layers... can't have too many layers.

commands to start with
VPOINT ROTATE
VIEW TOOLBAR
VIEWPORTS TOOLBAR
VIEW (save restore)
BOX
CYLINDER
UNION
SUBTRACT
SLICE
SOLIDEDIT

Actually I have the book.  I even took the course about ten years ago.  Forgot everything.  So after I look at the book what is the best way to do 3d.  Wireframe or solid objects?

Let the debates begin. I say solid, unless of course, you just can't make it work, then add some meshes to it.

What's the nature of the 3d?

If it's architectural, get ADT or Revit.

I am just playing around and thought it would be fun to look at 3d again.  We do mostly residential so there is no real need but knowledge is always worth something.

That's true. Check out intersection and subtract. Those can be the most flustering ones. You can get some pretty interesting intersections if you really dig deep.

I would say you would outline your floor plan with a pline (make sure all lines are joined together) and extrude this outline a given height.

Simple 4 sided house.......
rectangle 36' x 24'.  offset for wall thickness (4"??? I'm no archie & it's been a looooong time).   Extrude both to 8".   Subtract the inside from the outside rect.  (hint: pick "subtract FROM", then "object to subtract"....it's kinda counter-intuitive.)  In the View toolbar pick a south-west iso view....you're now looking at the south-west corner.  change your ucs to front. draw a rectangle 3" x 7".  Move this from bottom midpoint of the rectangle to bottom mid of the front (south) wall.  Now extrude the rect -4".  Next subtract the door from the house.  That should get you started.....I got here at 6AM....I'm out-a here for the weekend!!!!!

Have a "goodie", gang.

Remember back in R12 when it was the other way around. Man that was a kicker trying to reverse the brain logic on that one.

Don't forget, 3d0rbit has lots of goodies to play with, including preset angles, like south-west iso.

I guess one man's intuitive is another's counter-intuitive.  

It always seemed straight forward to me, 6-4=2,
starting thing MINUS what you don't need EQUALS remainder.

but again,
that's just me

I don't have a problem either way. Heck, -4+6=2 as well. I don't care how they do it, but changing the order when you're used to doing it one way just screws with the brain waves to make the hands do differently, what you just learned them to do.

As I recall in R12, it was the AME (Advanced Modeling Extension) that worked with "solids" after a type (non-Acis).  AME was an aftermarket add-on, that was not fully under the control of ADESK, though marketed by them as an extension to autocad.

R13 was the first with ACIS solids, and the order there was always as it is now.... and that was over 10 years ago.

BTW, strictly speaking, -4+6=2 is addition not subtraction, you're adding 6 to the starting number.  :wink:

Sorry. You still reach 2, though, just in reverse, but your AME to acis makes sense. I'd forgotten about AME. It was just hard to make the change when it happened is all I'm trying to say.

You're trying to pick an argument and I'm done, because I'm going home. Good day sir.

Draw your floor plan. Select all the lines and give them a thickness (floor to ceiling).

VERY BASIC 3D plan.

3DO will let u scroll around.
