scheduled Crooked Staircase

[martinfdc]

Hi,

 

I'm creating a staircase with the Stair Tool but I'm encountering problems with the second stage of treads. From TOP/PLAN the staircase appears all straight and lined up. But when seen from TOP the second stage of treads appears slightly crooked. It's a tiny bit but the treads are not truly at 90 degrees. Maybe there is something wrong with my settings... but I don't think so. Also I get a weird set of circular lines... (this is not as bad of a problem as the treads are)

 

I think the problem occurs when I set the STAIR LANDING CORNERS radius.

 

I leave a set of screenshots that explain the problem.

I leave the VW 2017 File so that someone can take a look at the file...

Crooked_Stair.vwx

Ok, I see it too.

 

Increasing Offset 1+2 does not help.

But setting the landing rounding just a bit smaller as the max. possible number (like 0,148 instead of 0,15)

makes the upper treads orthogonal again.

I would say this is a bug.

 

Don't know why the Meshing is so bad and if there could be any improvements.

@zoomerI didn't manage to make the upper treads orthogonal but I did manage to remove the weird meshing (via changing the outer radius)...

 

anyhow, this is probably a bug as one should be able to draw the staircase with the exact dimensions one wants...

 

I leave two screenshot so that you see what I'm talking about.

Didn't really check if the treads are ok, they just looked ok

Indeed, they are not.

 

Interesting, the Mesh Problem "Solution"

BTW,

 

I linked that problem to the german VW Computerworks Forum.

I think they build the stair tool. Hope they will look at it.

"Good" to hear that in your case also the treads are not aligned...  

 

Great! I hope they find a solution to it.

@JimW do you also experience this issue?

I do not, when I open this file the steps seem to be dead straight:

@JimWPlease look at the stair using TOP as a view not Top/Plan. Then you should be able to see the problem.

It did it initially in Top but now seems to be straight in both. If I reload the file I see the crooked line but then upon any draw or object regen it corrects itself. However it isn't file specific, if I create a Stair with similar settings I can recreate the crookedness intermittently, I'll pass this along to see if someone can nail it down.

Depending on Stair input you may barely see it.

You will see it in the cursor values when you draw a line over a tread.

Even than you have to care to not get the helper lines that want to palm

an "horizontal/vertical" intersection point snap to you
