Hi there holligan,
Not quite up to speed but this should give you a start.
This is with Turbocad 4 hope 7 is similar.
From the menu across the top select 'INSERT'/'OBJECT'
On the window that opens is a list of progs that you can insert from. Select the prog. In my case I used PSP7.
Select 'CREATE FROM FILE'
Select 'BROWSE' and choose the picture you have saved in PSP7 and want to use.
Select 'OPEN' then 'OK' in the box showing.
This will open the chosen picture in TCAD.
In this way you could have a list somewhere to use as above.
However - to get that picture into 'MY SYMBOLS' do the following.
Resize the picture in TCAD window to full size using corner handles.
Then 'FILE'/'SAVE AS'In the resulting box select 'MY SYMBOLS'in save as box. Found under c/imsi/symbols and so on.
Name the file and save as TCW.
When you open 'MY SYMBOL LIBRARY FOLDER' in TCAD the picture should appear.
However this is where I cannot quite get it right for size/to drag in to TCAD cleanly.
You might like to clean up the act from there on.
Anyway, this will put you to the top again for more knowledgeable people.
