possible method to draw a 3D structure by PDB or Blast or swiss model

Question

[saikishoremudhiraj2311]

I think Homology modeling predicts the 3D structure compared to protein threading, but I do have one question like is that possible to draw a 3D structure by PDB or Blast or swiss model or any combination of these tools.

I think Homology modeling predicts the 3D structure compared to protein threading,

As far as I know, if your query protein has a close homolog whose structure is known, that homolog can be used to predict parts of the query protein's structure. Protein threading can be used in certain cases when close homologs are not available to predict the broader fold structure of the query protein. It's not an apples-to-apples comparison.

is that possible to draw a 3D structure by PDB or Blast or swiss model or any combination of these tools

These tools can render PDB files graphically, but I am not sure if you can programmatically draw structures ab initio.
