Macro to save active drawing as PDF file into selected output folder and close drawing

This VBA macro performs the following steps with the active SOLIDWORKS drawing:

• Shows Browse For Folder dialog to select the output folder for the PDF file
• Saves the active drawing as PDF file into the folder selected in the previous step. File name of the PDF will be the same as file name of the drawing
• If the original drawing was modified, macro saves the changes
• Closes the active SOLIDWORKS drawing document
