Combine multiple Line length and existing text in one attribute block

[alanjt]

Or use a couple vlax-curve* functions and don't sweat a difference b/w line and arc, since it will accept any valid curve. Granted, you are still using VLISP, as opposed to Lee's suggestion, which keeps every thing in ALISP.

 

(defun _length (curve) (vlax-curve-getDistAtParam curve (vlax-curve-getEndParam curve)))

Such simplistic geometric relationships follow from the definition of the radian being the angle swept by an arc whose arc-length equals its radius - i.e. for every radian turned about the center, you are traversing a distance equal to the radius along the arc.

 

Yup, short and simple. Very nice suggestion >

 

Thank you for the info LM.

Makes sense to me. Lee is always the one to go to with math related questions.

I have read the notes in a hurry but I think the answer is no up to now , but we may find another way to do the notes if you have explained your needs of these issues clearly and in a new thread of course .

 

And for the Block size , I think I have made the Block with the Units or cm and not mm , so just ignore it and create a new one with a new name and add it to the code .

 

Good luck

 

Thank you Mr. Tharwat for the Great Help,

 

This file saved me a lot of time.

How am i using this Method, well, This method is used to create Attribute blocks in the drawings containing the duct information: Length, Width, Depth, I will then send those Attribute blocks to Excel and i will Calculate the duct Area and weight.

 

Hope this method comes handy to somebody who wants to save a lot of time calculating duct area and weight.

 

Thank you all who participated, your input is Highly Appreciated.
