Guys,
Here is what I'm trying to do and I need some sugestions from you
We are working for a lot of subdivisions and I need to develop a program that will write the area of a polyline (closed) into an attribute of a block. of course if I modifiy the pline the area should be updated automatically. I have a function from acadX.com that will do that (kind of). This function is using a text instead of block and is linking as an extended data the handle of text entity to the polyline..but if the user is moving this text to paper space or copying the text somewhere else the link is lost. This is right because autocad will create a new entity with a new handle. Now I'm thinking that I should reverse: attach the pline handle into an invisible att of my block and when the user is changing the pline the blocks to be updated. In this way does not matter whether
the user is moving (or copying) the block in pspace or mspace. Am I right or
?
Who is working in subdivisions will know that I'm talking about sanitary or storm areas.
I don't need to update this areas in real time with a reactor, I can have a routine for initial creeation (which will insert the blocks and initial area) and one for updates.
Any suggestions??
And another question (off topic) I'm trying to animate my subdivision with autodesk viz. Do you know which would be the best method to import my surface into viz. 3dgrid, 3dfaces or contours and the use terrain tool in viz??
Thanks a lot
