I used Autocad.
I had to join the lines then used the extrude command.
The cross flames has three lines these need to be joined and also a bottom needs to be added.
Also the lines that make up the heart need to be joined.
In autocad to make a 3d solid from 2d the 2d must be a closed single polyline.
Not sure about turbocad sorry.
Also not sure what you mean by a "band" in the above the heart is .5 , cross/flame .75 |
