topographical autocad import problem..help

[Keyser Soze]

Hi all, i need some help importing this cadd drawing into CA, the contour lines do not import. I have tried making them terrain lines and not and in both instances they do not show up. Can someone have a look and see if they can import this dwg. The units for import are m.
Thanks in advance.

I have found that when it come to topo lines, you are better off drawing/tracing over them. When you import dwg topo lines, they end up having way too many segments, and completely slow down a plan.

You need to rescale the lines, they are too small to see without that.
They are there just way too small.

Andy, I am not sure what you mean. I have imported the drawing and every thing is the proper scale, how could the contour lines be a different scale?

[carpenterguy]

Ah, I see, the units are in meters and imported as mm.
Perhaps you can use the All-on Set to see if the layers are turned on.

I tried the all on set, it seems that the contour line labels are on the contour level as well as a few contour lines but most contour lines are not there.
I was hoping someone could try importing and see if they get the same thing.
I do not have a working copy of autocad to test to see if the contour lines are there.

Download a free autocad viewer, there are lots of them

Flatten contour lines before exporting to Chief.

Lines are drawn above Z axis.

Cad drawing is not to scale too.

See attached.

Hi chiefer, how do you know the drawing is not to scale, it is hard to see on your attached view.

Thanks by the way for looking at it.

[Chiefer]

I'm sorry it to scale but in meters not mm.

[Keyser Soze]

Yes, i opened the cad dwg and it appears as you have said the contours are above the drawing in the z axis, would they not be based on the elevations that each line is?
Why wouldn't chief see this and import as required?

[Chiefer]

I have no idea why it would not import to Chief. You may have to trace the lines again.

Here's what the terrain would look in 3d.

[Chiefer]

I think Chief will only read lines if they are drawn at Z=0.

[Keyser Soze]

Chiefer did you do that in CA?

[Chiefer]

I did it in Max. Here's the 3ds file.
