Hello,
You can also copy (Ctrl- or cmd-C) the 2D elements you've drawn in your plan view and then :
1 - paste them into the 2D Symbol window of the object (to create a new object, go to File->Libraries and objects->New object...).
2 - After that, just write the following line in the 2D script window:
fragment2 ALL, 0
It will prevent your object to be stretched.
