Drawning to different 3d walls/objects ?

[petteri]

Problem im having, if trying to draw example floor to for example polysolid object, it does not start drawing on the right way and

 

Holes to different "3d" rectangle walls ( top,left bottom etc ) ,extending rectangle to upwards z-axis with multiple rectangles it wont start drawning it to up from the same platform

 

 

im always facing to this same issue, it wont start drawning from the right place i want

 

 

did anyone understant what i was meaning ?

my settings are in 3d basics

 

 

thankfull for replys ( you guys can also teach me english if im using wrong words )

So you are using the Polysolid command to create your walls. Sounds good.

 

What do you mean "it won't start drawing from the right place"? Are you having trouble placing the wall?

 

What dimensions are you using for the width of your walls and the height of your walls?

 

Can you post an image or the drawing file itself?

You probably need to adjust your UCS. When working in 3d (and in my opinion 2d) always have your UCS icon visible.

 

The reason for this is when you extrude objects to create a solid body the extrusion is done in the z-axis. So in the case of walls which are at differing angles, to place objects in relation to one wall or another you need to reorient the UCS. It will take a little practice but I'm sure you'll pick it up in no time.

One way to control your UCS, since you are using 2011, is via the Dynamic UCS which you will find a button for at the bottom of your screen located next to the Dynamic Input button. There are other methods as well.

try vpoint 1,1,1 this gives a good 3d view of your object extrude all your objects in a plan view including those to be used to CUT holes in the walls, a simple way then is to use rotate3d to rotate them about the X or Y axis and then move them using snap to the correct location on a wall. You can move them verticaly also by move pickobj 0,0,0 0,0,height then use SUBTRACT to make hole.

 

I would though tend to go more down a ucs path eg say a circle hole in a wall

eg draw outside & inside pline extrude both to new height Subtract inside from outside, then vpoint 1,1,1

ucs 3 pick origin pt say lower left corner then right pt on bottom then vertical this makes the ucs on the plane of your object UCS S SIDE1 may want it later

type plan you are now drawing on the ucs plane draw object extrude etc go back to vpoint 1,1,1 use subtract hey hole in wall.

 

Any time ucs w plan returns to normal drafting plane UCS R side1 returns to wall plane but you will need a 3d view point to see it.

for a better explain is problem has been how to move on x y z axis-directions for an example, how to start drawning from x direction to upwards on -z direction ?

 

 

UCS fix helps me with this ?

 

I have looked Tutorial lesson 1 but i cant understant it completely

 

 

yep this is bit noobish, but atleast im at right threadsection

You have to change the orientation of your UCS. First it must be turned on. Have you at least done that?

[petteri]

I have it turned on, toggle is in between dynamic input and object snap tracking, thanks ill try with these tips

Keep in mind that AutoCAD wants to Extrude in the positive "Z" direction unless you override this by inputting a negative number or, as in the case of the PressPull command, you move your cursor in the direction opposite to positive "Z".

[ReMark]

Maybe this will help.

 

To the left is the default position of your UCS icon. Notice that "Z" is point up. I've drawn a rectangle and then extruded it to show you the results in both 2D and 3D.

 

To the right the UCS position has been rotated. Notice that "Y" is pointing up. I've drawn a rectangle and extruded it to show you the results in both 2D and 3D.

 

Does this help you to understand what is happening when the UCS is rotated?

 

[petteri]

Thanks this UCS helped me alot, ( rightup corner newucs button )

 

 

Final question abit offtopic but thankfull if i get answer

 

 

How do i make floor to my polysolid object ? or any other drawings ?

 

thanks alot u guys are super

[ReMark]

A floor has a thickness too. What kind of floor? Concrete, wood, tile, other?

[petteri]

i have one project where im using 0.5mil metalplate so it will be just 0.5mil thickness

 

(tower i have made by polysolid command)

 

 

This project is drawning a churchtower, i can post picture when i have done it bit further

[ReMark]

Then that's what you extrude it to.

[petteri]

hmm tried to extrude but there is no targets to extrude

 

 

 

UCS cant take target from the bottom (bottom of the polysolid rectangle)

so i cant draw for example Rectangle on the bottom as a floor and extrude it ?

[ReMark]

Sure you can. But if you're UCS has "Z" pointing straight up then you have to input a negative value for "Z" not a positive value. I use negative values for "Z" often.

thank you very much, it worked

[ReMark]

thank you very much, it worked

 

As I had expected it to.

 

You're entirely welcomed.
