clearing of the covering units

[Giovannino60]

I have to delete some covering units and I have proceeded like this:
1) click on the selerapid command line
2) In the object type, select Covering Units.
3) in operator, click on select everything
4) click then delete


in some files went well, in others in object type, does not exit the covering unit item, but only multiple, block reference, rotated quota.
You know how to solve the problem?

Thank you.

...the voice doesn't come out. . .

because there are no...

then why when I pass close to parts of the drawing, imported from archicad 15, there are lines that are normally hidden, what can I do to make them visible?
in another file I proceeded as above and solved the problem, but with this file I can't, when I approach with the mouse the lines are highlighted when they flood me disappear.
Thank you.

notoriously the export in dwg of archicad is not the maximum and it happens that you insert the "sporcizia". . .

Maybe they are blocks with opacity lines 0

try editing blocks

I went to iserisci>editor blocks I clicked on a list block all showed up on a screen with the block magnified to gray background and now what should I do?
Thank you.

analyzes the block components using the quick filter (selerapid).
