One question...

Theme: Front panel

How can I avoid these "Polygon not closed" errors?
I have a rectangular inner breakout with little inner nooks of 1.75 mm in the corners. I placed a rectangular breakout with round corners and replaced the arcs in the corners with lines on layer 30 (Front panel contours) for my nooks. All ends meet exactly. When calculating the panel, I get several errors "Polygon not closed!":

 1 (Fig. 1: Errors regarding the corners)

Answer: This comes from the fact, that the long lines belong to a component and the short lines in the corners are free lines. TARGET does not recognize that they belong to the same structure.Start again with a rectangular breakout with corner radius 1 mm. Click onto the 4 arcs and change them into sharp bends:

Now switch the grid in menu "View" to 0.05 mm. Place the relative coordinates origin exactly onto one corner using key [Pos 1] or [Home].

Then click onto this corner and insert a nook into the corner:

 5 (Fig. 5: Also the small lines must belong to the Breakout!)
