i want it to be like this
but when i click the minus front, both objects got cut out like this;
so how? how do you combine it like in the first picture?
here the 2 original objects before i click minus front;
Pathfinder Toolset is very good for some tasks, but it's not the only boolean operator in Illustrator. The
Shape Builder Tool (Shift+M by default) is what I would recommend in this case.
If you hold down Shift, you can delete the sections of lines that are between intersections of selected Items.
I post an answer instead of comment because I use pictures.
If I had the picture as you and needed to create the picture you need I'd do the follows:
Select the upper shape and click
Object->Path->Divide Objects Below
I've got this picture -
After I join the two selected triangles in pathfinder by pressing Join button and this is the final image -
remember, that your question could be marked as unclear by moderators.
Flash is really good for this sort of drawing
When not in 'Object Drawing mode', Flash will automatically treat all intersections of lines and fills in the same malleable way the Path Finder tool operates.
If your objects are already grouped, just break them apart to 'flatten' them into lines and fills.
Once everything is 'flattened' in the same layer, you can use the Selection Tool to adjust intersection points, remove line segments, pull bends in lines, delete fills, etc. You can double-click a line to select all connected lines or double click a fill to select all surrounding lines.
