Why material properties of layups is not imported in external model to structural?

  I have modeled composite layup in ACP and did a linear buckling. After that i imported it to apdl and saved it as .cbd file. Then I import it to external model and transfer it to static structural. Then i opened the the model it shows some question mark in the layup section shown here.
  
  Why it shows like this? How can i resolve this.

  Looking at the help, only the following commands are supported using External Model.
  
  MPTEMP, MPDATA, TB, TBDATA
  
  So, Clearly something is missing or not transferring due to incompatibility. Why not re-define the materials in Engineering data instead?

  Sandeep sir,
  
  I didn't get your point correctly.
  
  I want to mention one point, while opening the ACP bloock it shows the following message
  
  Also, if we create the material properties with our own data, static structutal does not accept it

  Hi,
  
  Looking at these messages and the screenshots, it must be your ACP material file is missing, and that's why you see no composite layup definition in Mechanical.
  
  One workaround is to create an ACP(Pre) component, define the layup there, and then link to static analysis.

  Thank you Wenlong.
  
  I have used the imported model just because of adding material imperfection. The steps you mentioned was already done.
