Why do my DIVIDE blocks appear somewhere else?

[marlon]

I've drawn a little 3D object. I switch to Plan view and draw a straight line. I want to divide that line into 3 segments, so I draw a small circle and use the BLOCK command to define a block using that circle.

 

Then I use the DIVIDE command to divide the line. After executing the command it's supposed to look like a line with 2 circles along its path, making 3 equal segments. The problem is the circles appear somewhere else - i think it's perpendicular to the XY plane.

 

When I create a new template (clicking File -> New) and do the same thing, there's no problem.

 

Please help. Thanks!!!

make sure you specify the basepoint of the block(0,0,0) at the centerpoint of the circle

Here's a link to a similar thread, same solution

I've changed the UCS using 3point several times already, does it have anything to do with my problem?

 

(I'm using autocad 2000 and 2002 on two computers)

 

On the Block Definition dialog box I click on Select Objects then click on the circle, then I click Pick Point and I click on the exact center of the circle.

 

The problem can be seen right away because on the Preview Icon frame in the Block Definition, instead of a circle icon, there's a straight line (side view of the circle?)

 

The similar thread you gave me may be a little complicated for me as I am just a beginner. But I'll take a look at it again later.

 

Also, on a new template, by doing the same procedure like the one above I get correct results. I tried selecting objects (via Select Objects) without selecting a base point and it resulted in the blocks appearing somewhere around the line. If anyone could explain to me why this is, maybe I can sort the problem myself.

 

Many thanks!

When you make the block, in the Block Definition Dialog Box, Under BASE POINT, check SPECIFY ON SCREEN. then select the circle center point as your base point.

I'm using an older version of autocad so there's no SPECIFY ON SCREEN, but I assure you I selected the circle center point as the base point.

 

I've drawn a 3D rectangle. 20x40 units and 300 units in length. On the two ends (the 20x40 sides) I can divide just fine.

 

 

 

Not so with the other two sides.

Notice the two circles on the left which SHOULD be aligned with the line.

 

See this Block Definition:

Notice the Preview icon of a line instead of a circle.

 

Sorry if I'm kinda slow.

Dont apologize

one question, did you make the circle in the block editor itself or you draw it on model space then block it? I suspect that the geometry icon is viewing the block from a top view of the circle.

I drew it on model space then BLOCKed it. Isn't that the correct way to do it? I've been trying to figure this out for days without success. Why can't I execute the DIVIDE command correctly even if I've already moved/changed the UCS to the appropriate side?

The problem may lie on the UCS.

In making blocks, to have their base points established correctly,reset UCS to UCS WORLD, Base point at UCS WORLD's 0,0,0 then block the objects.

[marlon]

Both the object to be divided and the block, in my case the line and the circle respectively, should be drawn on UCS world. I'm not sure about the 0,0,0 though, but it worked for me. The blocks of circles would appear like lines but it's ok because I use the centerpoint osnap. Or I could use small lines as blocks. Thanks a lot!

[nocturne00]

Hey glad it worked for you, but it looks like you solved most of the problem by yourself.

ucs world's 0,0,0 is important coz its the node or point in w/c the block snaps onto the the object being measured or divided.
