Polyline Behaviour changed?

Polyline Behaviour changed?

Anonymous
No aplicable

I am a little puzzled by a change I just noticed. From time to time, I will draw poly lines that consist of a linked series of arcs and lines. To get the feel right, I depend heavily on  undo, in the middle of the process. Up until 2015, if I was drawing an arc and I hit undo, the default behaviour was to go back to the extension of the previous arc or line with a tangent arc and I could continue.  In 2018, the after I hit undo the new arc behaves with some kind of included angle behavious that is essentially worthless. What is the point of this?

Not sure what your trying to say perhaps a screen shot would help

Here's the difference. In both cases I have been drawing a polyline as a series of arcs.
After hitting a point, I undo (to back up and try a different point
In 2015 (what I want)

Have you tried the option of holding the ctrl key to switch direction?

Can't get to a scren shot with the command line, but it's:

PL (for polyline)

[*first point]

[*second point]

A [arc option]

[*point]

[*point]

[*point]

u [undo the last point]

so ortho is not the answer sorry. a work around perhaps is just make the arcs separately and then pedit them tougher when you got them how you want them

No joy with ortho off - same behavior

Change Direction inverts the curve, (but does not make it tangent)

So the problem as I see you want to undo an arch but not change the last arc.

You need to finish the arc command and not hit undo in the middle. so pick a point even if its not right then undo and you can select a new point

Thanks: I am unable to replace the error in R2018 or R2019 here using the commandline sequences you listed while clicking points in a diagonal across my screen like in your screenshots.
EXCEPT if the ARC size changes when I move the cursor to an odd angle. But this is very hard to replicate on demand (found it by accident after the 10th try).

Is that how you are doing it?

No, not exactly. I am trying to get a single polyline that is a series of arcs and sometime line segments, where the arcs are all tangents.

 

Sometimes, the location of the point setting a previous arc limits my current arc from going where  I want it to.

No. It's consistent.
I am thinking it is some kind of oddball variable? But I'm not sure I would know it if I see it.

Hi,

 

>> I'm sticking with 2015 for the time being

I can't reproduce the issue with AutoCAD 2019. So let us first look to your currently installed updates, start command _ABOUT and show us a screenshot from that dialog (it should show 2019.1.2 ... otherwise your AutoCAD is  not up-to-date).

 

That's what I get following your steps:

Yeah. I know it's only 2018
Unfortunately, since I have 8 workstations, if I want to move to the latest and greatest, I have to upgrade all of them.
And if it's not fixed, then I am totally SOL. So as I said, sticking with 2015, til I know why this doesn't work.
But thanks for digging in. The fact that it's not reproducible is encouraging, believe it or not.

Hi,

No, it's not 2018, the video I have shown works in the same way in 2019 as in 2018.

It's something on your systems (or missing updated for your 2018, mine is O.161.0.0 AutoCAD 2018.1.2 Update)
