Wall separation line when reference line is not align

Heftor
Booster

Hi everyone,

I'm getting an unwanted separation line in my composite wall, the wall has different thickness in different places so i cannot find a way to keep the reference line align.

The line appears exactly where the wall thickness changes, Is there a setting I'm missing?

 

Thanks in advance

Hector

Walls only get "connected" if their reference lines touch.

Try to play with the possibility to move one of the ref lines.

However, you will find that even while now the walls are connected, the outer skins are not.

You can try to put in another small orthogonal segment in between.

It needs to be made from the thicker wall (right pic) for it to clear (mostly) without any visible glitches in 2D.

 

Last possible solution is to do the classic Murray and clean up with a column.

HI all,

 

In addition to @runxel very good solution, here's my workflow for this situation.

 

1) I deactivate the (Start/End) line of the wall with the smaller thickness (in this case the Start one), as attached,

2) For the corner of the wall I draw a complex wall while deactivating both of the end lines, as attached,

I hope that helps.

Thanks @runxel for the tip, I have aligned the ref. line and looks better.

In this case, I think I cannot use the thicker wall trick to fix the corner, but I have a small wall for this case, but I will try Murray´s method, which looks nice.

Hi Mahmoud Qenawi,

 

Nice tip, I was not aware of that option on the settings of the wall. I imagine it will come handy for some situations, 

 

Thanks for the help.

 

Regards, 

Hector
