Inserting Slab

[shr]

Hello. I am trying to understand why when I draw a slab on a Layer that has Z=0 and +-Z=3000, it puts it in at +3000 and not at 0. In the insertion options the Datum offset is 0.

Also when I draw a ceiling (also Datum offset = 0) it puts in at +6000.

I tried a different layer with datum +-Z=2700 and the slab is still put in at +3000.

Where is it getting the +3000 from??

This doesn't happen when I draw a slab; it comes in at the right elevation. Are you sure you have the correct numbers in the layer's height dialog box?

[Jonathan Pickup]

if you are using the slab tool, what settings are you using for the slab datum, in the slab preferences?

If you place a 3d locus (Shift 0) on a corner point on the top-face of the slab is it really at 3000mm?

I remember an issue like this being solved by toggling the document units or re-setting the Z and ΔZ to 0 and back again. You might try that.

It's also possible that your reference datum is at -3000mm.

Can you share a screen-shot of your layer setup?

Mitch,

In a new drawing, inserting the slab on ground Layer which has Z=0 and Delta Z=0

Jonathon,

the slab is NZ 100mm concrete slab - Datum Offset from Layer Z=0

BCD,

3d locus on same layer inserts at 0.

Not sure how you toggle the document units.

Is there another place for the reference datum, other than in the Slab Preferences?
