【转帖】create tangent relationship
 

create tangent relationship
is it possible to create tangent realtionships in a sketch between all horizontal & vertical lines and their adjoining radii by using a macro? my intention is to fully define tha sketch by dimensioning it myself as the fully define function is not suitable for my type of sketches.

hey feroz,
are you creating the sketch with the code too? if so you can use the sketch segments of the sketch and add the relations you require.
to add tangent relationships use the following:
modeldoc.sketchaddconstraints("sgtangent")

stavros,
i bring in an iges part and create a sketch by using the convert entities function.i then delete all the " on edge " relations.

errr from the top of my head...
from the sketch you can get all the sketch segments (sketch::getsketchsegments) and using the sketchsegment::gettype you can see the type of each of the sketch segments to differentiate between lines and other sketch segments.
now i am not sure if the sketch segments (that are returned in an array) are returned continuously i.e. intersecting segments one after the other...
i will try this tomorrow and i'll give you some feedback. in the meantime if you can upload a here an example of a sketch i can play with that will be great.
cheers,

ivana,
thank you. this macro works like a charm. it would save me a lot of time.
