how to create fillet in autocad ? You can link arcs of two objects through the Fillet function in AutoCAD，like ZWCAD+, at the same time, you can also trim or extend the objects.
Enter fillet or click Home » Modify » Fillet
Execute the Fillet command
Input R, enter, input fillet radius (e.g. picture 1, 50)
Input T, enter, input Trim or No trim, enter
Set parameter, if the needed parameter is not the same as the default then omit this part.
Select the first and second objects, end fillet.
If you input P when setting parameter, you can select multiple edges, and you can create 2D fillet; if you input U when setting parameter, you can select multiple fillets, and you can also select N pairs of edges according to the original setting, and therefore create N fillets.
Besides, if you set the fillet radius as 0, you cannot create arc, and the selected objects will be trimmed or extended to intersect with each other. When two lines are intersected or disconnected, they can be trimmed or extended automatically through Fillet command (e.g. picture 1), it is more convenient than using the Trim and Extend commands.
