Question on Ruby Problem

[ktkoh]

Working on a new woodworking joint rb starting with dowel joint and I have this problem passing a negative number to a procedure.

    points_DowelCircle_Comp1(@xcl[i],ycl)

    def points_DowelCircle_Comp1(x,y)
    UI.messagebox("x = " + x.to_s)
    UI.messagebox("y = " + y.to_s)
    r=@@dia/2
    @pt[0]=Geom;;Point3d.new(x+r,y,0)
    @pt[1]=Geom;;Point3d.new(x+(0.866*r),y+(0.5*r),0)
    @pt[2]=Geom;;Point3d.new(x+(0.5*r),y+(0.866*r),0)
    @pt[3]=Geom;;Point3d.new(x,y+r,0)
    @pt[4]=Geom;;Point3d.new(x-(0.5*r),y+(0.866*r),0)
    @pt[5]=Geom;;Point3d.new(x-(0.866*r),y+(0.5*r),0)
    @pt[6]=Geom;;Point3d.new(x-r,y,0)
    @pt[7]=Geom;;Point3d.new(x-(0.866*r),y-(0.5*r),0)
    @pt[8]=Geom;;Point3d.new(x-(0.5*r),y-(0.866*r),0)
    @pt[9]=Geom;;Point3d.new(x,y-r,0)
    @pt[10]=Geom;;Point3d.new(x+(0.5*r),y-(0.866*r),0)
    @pt[11]=Geom;;Point3d.new(x+(0.866*r),y-(0.5*r),0)
    
    #Debug @pt.each {|e| UI.messagebox("point = "+ e.to_s)}
    
  end #points_DowelCircle

When @xcl[i] is a negative number ie. -0.375 the program quits and the UI.messagebox at the start of the method does not happen. What am I doing wrong?

I suspect you haven't shown us the right bit of the code that's failing...
I also assume you get no errors in the Ruby Console ??
add a line in front of this...
points_DowelCircle_Comp1(@xcl[i],ycl)
like
**puts @xcl[i] puts @xcl[i].class** points_DowelCircle_Comp1(@xcl[i],ycl)
???

Thanks TIG as usual you were right on the problem and I found the error earlier in the code and it resulted in dir_y did not exist and program did not actually reach the point I thought was the problem.
