This is the version I am inflicted with right now.?ÿ Never thought I would say Cyclone is better software 😉
It has several weird polyline bugs (can't remember them all).
The latest I have encountered...in all previous versions to draw anything from cogo point to cogo point, for example:
PLINE
'pn
1001 (starting point number)
1002
1003 etc.
Draws a point line from point to point to point, doesn't matter if OSNAP is on or off.
In C3D 2016 it no longer works right, if a surface is on it does all kinds of weird stuff then if the surface is frozen yet it still snaps to 3d polylines even if OSNAP is off.
I find myself freezing layers trying to get it to do what I want.
This is aggravating, to say the least, but I'm not bitter about it.
The only thing worse than C3D 2016 is C3D 2018.
I truly hate this software
Dave,
Im not sure what is going on in your setup, but it is still working fine in my 2016. The Pline takes the elevation from the first point and stays a true pline through the rest of the point numbers entered.
A couple of thoughts. As above, "pline" creates a 2D polyline with its elevation taken from the first point that you snap onto, if you snap onto a point, otherwise it will have elevation zero. "3dpoly" creates a 3D polyline with vertices taking the elevation of any point snap on to. If unwanted snapping is an issue, make sure 3d object snap is off - to toggle it, command line is "3dosnap", or pick the icon in the screenshot below. If that icon isn't showing, get it from the menu bar on the bottom right. Alternatively, toggle it with F4. (F3 toggles 2D object snap).
Note that in Civil3D you can change 3D polylines into 2D.
It still works on C3D 2016 & 2018 for me.
I've never experienced any issues with drawing polylines. Your surface shouldn't have any impact. Do you have all the service packs and hot fixes installed? Are you sure you're in World UCS?
my 2 cents
'pn works fine for my 2016 setup
try an old job?ÿ ?ÿperhaps your current?ÿ template?ÿ , blank?ÿ .dwg had a variable change
or
make sure the point style is elevation = zero
