Did you actually unsoften the edges or just unhide them?

I agree with nickchun, you should right click the edges and select entity Info to make sure they are not soften.
Also, you may need to change all face to triangles depend on which format you want to export to.

You can use the VCB to specify the offset (see page 13).

I know this. But this is not what I want to ask.
You can see that after push/pull a curved surface, distance between a point in new created face and its origin in old surface is not equal to offset.
I think that it may be more accurate if we could make offset 'mean' the distance between these point. I not sure and am asking for opinion.

Hello,
First, thanks fredo6 for making JPP.
Although Joint push pull help me a lot in making model (I used many arc and curved surface), I see that JPP only set offset by face and in my case this is a little hard for me. With curved surface or line, I think measure length between points is more accurate than between faces or edges. The basic circle tool also measure radius by distance between center and an endpoint. With my current knowledge, I don't know how to make my model more accurate with JPP(although, as I explained above, I'm not sure which way is actually more accurate).
So please tell me your opinion about ways of measuring.
If you agree with me could you show me a way/tip/trick to thicken a curved surface (for instance, a sphere, or a egg shape for a little more complexity) to a exact thickness, measure by distances between points.
Hope that my question is clear enough, I don't work or study in designing.
Thank you,

Hello. I have been in forum for a while but have not posted anything, I use SU for my hobbies with not much knowledge in designing so I'm still learning.
I'm quite happy with new feature in sketchucation tools 2.6 but I have similar problems as tommy.jhd.
Sketchup start much slower with sketchucation tools enabled. Delay time is about 5s or more, sometimes, it crashes. Disable sketchucation tools make every things normal.
Although you have explain the cause, could you show me a fix or workaround (not to disable the tools).
I'm using win 7 32bit sketchup 8 free.
Thank you,
