problem

[ing.samu]

gent. mi del forum,
I have already introduced myself last time.. .

I need to understand why when I say lines,
the height of the quota, from the segment just made, is always different.. .

ex:
design a segment
imposed the garden
quoting the segment with the osnap
type keyboard height from the segment

Why is height always diersa?

Thank you for the kind answer

samuele

rather strange... do you want to post some screenshots?

Well if I have well understood what you do, you click the two extremes of measurement from the quota and after from the keyboard a numerical value, which you would like to be the distance between segment quoted and line of the quota.
Despite the fact that this numerical value is always equal, the distance between segment and quota line is always different.

If I understand, I can tell you that autocad behavior is absolutely correct.
This is because when you give the point to place the quota line, you give a numerical value, and you give it in a synthetic way (only the number), so autocad assumes that it is the distance between the last clicked point and the new point, according to the director that connects the last point of altitude and the current position of the mouse.
since the quota must be parallel to the listed segment, in fact the distance given in this way is equal to the component perpendicular to the quota, of the segment given by your numerical value, with angle equal to the last point of quota-position of the mouse at the time of typing the number.
You will understand that it is impossible to always have the same number.

different thing if you type the distance would be @dist<ang, that is a distance referred to the untimate point, but with a certain angle.

but why give a numerical value? may make sense to the first quota, but from the second on, just click on the previous quota. .

I didn't understand a thing... but aren't you taking the "aligned" command instead of "linear"?

lightning, then

he makes the quota, then to place the quota line type from keyboard the distance a-b, imagining that is the distance dist.

but typed like this, no angle, for autocad means an a-b length in the current position direction of the mouse cursor.

this will imply that the position of the quota line will be c-d (in case of horizontal quota) or a-d (in case of vertical quota)

since when typing the a-b distance, for each quota, the location el mouse will always be randomly compared to point a, goes from whether the resulting c-d or a-d will be different.

That's why autocad behaves properly.
