默认 【转帖】dim text positioning

dim text positioning
dim text positioning
if the is0 option is on in a dimstyle, and the text is outside the witness lines, the text is drawn horizontally, else it is drawn along the dim line (that's what the autocas doc says)
does dd provides a means to know if the text of a dim lies inside or outside of the witness lines ?
it seems that the criteria " inside/ouside witness lines" is fairly dependent of many others dim variables ( dimexo,dimexe,...) and fairly complex to compute.
thanks for any idea

hello dublin,
you are right the criteria " inside/ouside witness lines" is dependent of many dim variables. it is caclulated during recompute dimension block but this information is inaccessible for dimension entity.
best regards,
sergey z.
hello serguey
if this info is available internally to dd ( even if we have to call for a dim block recompute .. as we already do to find the standard text position... )
would it be possible that you make this info available to us with something like
bool pdim->istextinsidewitnesslines()....
thanks
jp
hello
what is the dimstyle variable which controls the iso like text drawing ?
thanks

hello dublin,
there are many dimstyle variables which controls text position. you can see extensions\recomputedimblock project as sample calculating text position (for example odalignedrecomputorengine.cpp adjusttextandarrowsplace(), adjusttextbyhor() and adjusttextbyver() and etc. methods).
p.s. if you describe your task more detail we could try to help you. addition new methods for access temporary (calculated) data is not good idea.
best regards,
sergey z.
hi serguey !
my exact problem, is to find the angle at which autocad will draw a dimension text on the display. it is fairly easy, analysing the various variables ( dimjust,dimtad,dimtih,dimtoh,....).
but there is a special case :
when the iso button is pushed in the dimstyle used for the dim, autocad forces the text to be drawn horizontally when"... the text is outside the witness lines..." whatever the other options are.
my problem in then to know if the text of a dim lies outside of the witness line.
or more precisely : what is the geometric meaning of ".. lies outside/inside witness lines..."
the question is simple,.. the answer looks complicated !
thanks

possible it will help to solve your problem. dimenstion has block ( dimblockid() ) with simple entites (line, arc, mtext and block reference) as result build block (recompute). you can find mtext in this block and get text direction.
if problem is more complicated you can try to use code from recomputedimblock project (see post above).
best regards,
sergey z.
