Problems

Hello nice to meet you all!First thead and post here about autocad 2009!!

I would like some uidance regarding some problems that i am facing right now and dont know exactly how to resolve them!

Well,the first one is that the UI is completely white not the uttons and sop,just the ''paper'' where one draws the lines and the second problem is that when i zoom in or out the mouse has his movements inverted ,meaning that when i move to go up the screen goes down and when i want to go down the screen moves up.....(kind of LOL situasion actually)

Forgive me if my language is a bit of but for some time now i dont use english so i am a little rusty!

Thanks in advance!

Welcome to the CADTutor forum Jio098.

If you would like the background of where you draw your objects to be a different color change it via Tools > Options > Display > Colors.

Context: 2D model space

Interface element: Uniform background

Color: White (change this to black)

An Options button is provided under the Menu Browser (big red "A") in AutoCAD 2009.

Thanks a lot,god my eyes were killing me with all that white over there!!

Thanks again!

You're welcomed.

What type of mouse are you using?

Reversing direction of your mouse zoom wheel...

im using a logitech mouse!

See my post previous to this one.

Saw it ,thank you!!!!!

And another question,to make a 3D from a 2D design ,what difference does it make if it is composed from many lines or costruction lines,?

Take straight out of the help file:

Lines (and Rays) (Concept)Lines that extend to infinity in one or both directions, known as rays and construction lines, respectively, can be used as references for creating other objects.

For example, you can use construction lines to find the center of a triangle, prepare multiple views of the same item, or create temporary intersections to use for object snaps.

Infinite lines do not change the total area of the drawing. Therefore, their infinite dimensions have no effect on zooming or viewpoints, and they are ignored by commands that display the drawing extents. You can move, rotate, and copy infinite lines just as you can move, rotate, and copy other objects. You may want to create infinite lines on a construction line layer that can be frozen or turned off before plotting.

so if i get this right to construct a 3D design it must have a closed dimension to read and construct,right?

Sorry Jio but your question is not evidently clear to me. But if I do understand it correctly though I would have to say no would be the answer.

It speeds things up going from 2D to 3D if you use closed polylines wherever possible. When you extrude a closed polyline you'll get a solid. I think that is what you are trying to achieve here right?

You can also extrude regions as well. Are you familiar with them?

Ahh there you go ReMark your explanation cleared that up for me. I retract my previous answer and reinstate it as a yes.

Thanks a lot,yes actually that explanation that Remark gave cleared the meaning errors of my question!

Thanks a lot guys!

What are regions really?

Something i've wondered, ReMark, or anyone i suppose, is there a difference if you make a polyline and extrude to make a 3d solid, or if you do the same to a region? Is the end result the same?

i've seen some places where it suggests tracing your lines/arcs with a polyline, and then extruding or sweeping, and i've wondered what the benefit of doing that versus using the regular lines and making a region. I don't know if that which i just said made sense. if it didn't, the first question i asked is all i really wanted to know. . .

To my eye the end results appear to be the same. You raise an interesting question though. I'll have to do some poking around.

I have a question about the measures in autocad,for example in i want to design a house what metric system do i have to use???

I experimented a little bit but it was quite confusing...

type in UNITS and then set your units to meters

Hello again! I wanted to ask how can i make parallel lines if the lines are inclinated?

there are a number of ways, here's a few ways...

Copy

Offset

use Parallel osnap
