I have set up "styles drawings" for my electrical, plumbing and appliances blocks. Some of the blocks are MV and some standard blocks. I have attached Property set definitions to them so I can schedule them in my drawings. I did block the MV blocks after attaching the PSD, should I not do that? I am having issues with the electrical and appliances blocks where the PSD is not attached when I insert them into my drawings. The plumbing blocks seem to all working perfectly. Do I treat the blocks differently than the MV blocks? Does it matter if I attach the PSD through the style manager than on the Extended Data tab on the properties palette? I have used PSD's forever, i am just stumped on this one.Thank you in advance for your assistance
