Can we combined a curved line in 1 line ? (delete corners, look picture)
You need a Weld plugin. There are several available, Tig Weld is very good also Fredo6’s Weld as part of his Curvizard tools. They are both available from Sketchucation. There may be a Weld extension in the extension warehouse.
If you are not already a member of SketchUcation, it’s easy to join.
There is a free-membership available - read the joining page links carefully.
That allows you to download plugins and take part in forums etc.
The modestly priced paid-options offer many advantages, like freebies, shop-discounts and monthly raffles etc…
thanks ! I do it
