Linetype text on 3D Polylines

[roberte]

Hi

Have had to do a few 3D utility drawings and was wondering is there a way to have linetype text that you can make on 2D polylines put on to 3D polylines.

Would be useful as at the moment I have been limited to using different coloured lines so that the 3D polylines for the utilies can be put to the correct depth below ground level. Would save me a lot of hassle of having to create separte 3D and 2D drawings.

For example if I had a Electricity linetype then a 2D polyline would have a solid line followed by a gap for the text then another solid line:

-------- Elec ---------

I believe you're out of luck there -- 3DPolylines do not honor non-continuous Linetypes [not even the simple ones without text elements or shapes in them].  You could use something that puts Text labels anywhere you pick along a 3DPolyline [or any other appropriate entity], aligned with its local direction, such as LabelTextMask.lsp here [the one attached to the second post on page 3], or if you don't mind taking chunks out of your 3DPolylines, LabelTextTrim low on page 2 of the same thread.  But they're workarounds, because either way, the text elements won't move along with the 3DPoly if you stretch the shape of it, as they would with a text-containing Linetype.  Also, it does work with 3DPolylines that slope in the Z direction, but puts the Text in under the current plan view, so it will be aligned in the XY but not Z aspects of the 3DPoly at the point of selection.  That may be better for informational purposes, depending on how steeply things slope [Text that aligns with the vertical slope could become unreadable in plan if the slope is steep enough].
