Message lost Grrrrr! when sending! Lynkoa bug! I'm doing it again!
1°) I saved the background map on the desktop and then put it with the WIndows file manager in the template directory.
2°) while I'm in admin mode I reopen the MEP drawing ==> I open the basemap ==> I slightly modify the basemap and save it. This time SW doesn't complain.
3°) I'm trying to create a new MEP with a different part and now I don't have any information in the templates while the info is present according to Windows
You have 2 types of files, drwdot (drawing template) and slddrt (background)
The location where you save your slddrt is a location for template files so you're not saving in the right format
You open SW, then your sldprt file, you save as and you choose document template (*.drwdot) you save it in the same place and you should have it in the tab.
The sldprt is when you right-click property on a sheet or when you add one:
I did what you said but I'm not sure I understood.
I managed to modify the basemap, to save it in Admin mode. Now it automatically gives me the 3 views and in addition the iso view. He took into account the changes and that's what counts
I'm going to leave it like this so it allows me to do my MEP.
I'm in V 2019 To put everything back in perfect I will have to switch to V 2O21 with maintenance (and there it stings).
