Do not quite understand the answer you gave (in link)...
1. I MUST enable "Use synbols". OK
2. In which directory should I put this image? - No answer
3. From help link: "You will have to ensure that your symbol has a Catalog and Spec record corresponding to its Dimensions (Pay attention to the following Database Fields: COMP_LEN, PIPE_OD, FLNG_TH, FLNG_OD, COMP_OD)".
I need element similar TEE. For me the important parameters - CTR_END_M, CTR_END_B, PIPE_OD
Have I to install them correctly?
4. From help link:"...the actual DWG symbol you create MUST be dimensionally proportionate to the Catalog/Spec record assigned to it"
I must draw this element according to data from the manufacturer ? And I have to draw this element for each value of the diameter?
