Command line: LIN_BOG
Ribbonbar: ProSig EPU -> Tools -> Drawing -> Line-Curve Sequence; ProTop -> Tools -> Drawing -> Line-Curve Sequence
The 'Line-Curve Sequence' function is designed to facilitate the process of drawing connected sequences of lines and/or curves. Having drawn a line-curve sequence, you will see a prompt asking whether you want it combined into a poly line.
The function starts by asking you to pick the starting point of the object sequence you want to draw. As soon as the program detects an object at the starting point you picked, it takes that point to set a user coordinate system (UCS) at a right angle to the object you picked, switching into Ortho mode at the same time. If more than one object is found, you will have to make some "subsequent picks" in order for the program to clearly identify them.
Here you have the following command options:
•"Pick Continuation Point or Curve (B), Reference Object (R), Back (Z), < End (E) > :"
•Having drawn at least one line or curve, you receive the additional option "(T)angent Curve":
•"Pick Continuation Point or Curve (B), (T)angent Curve, Reference Object (R), Back (Z), < End (E) > :"
Continuation Point:
When you pick a point, the program draws a line from the starting point you picked earlier (or from the last continuation point) to this new point.
Curve:
When you select this option, the program draws a curve defined by one point you picked as starting point and by another point you have to pick as end point. As you define the curve in its final form, you will see all the CURVE command options that you need at this stage. The only point to remember is that picking a radius too small will cause not only your implicitly initiated CURVE command to abort but the entire function as well.
Note: By using both ORTHO mode and the start direction option, you can create a tangent connection for the curve.
Reference Object:
Selecting this function allows you to draw a new line parallel or perpendicular to an existing line or to draw a new curve concentrically to an existing curve. Furthermore, existing objects can be components of a block. Due to the implicit use of the CURVE command, the new curve to be drawn - prior to being defined in its final form by picking the enclosed angle - will always be presented as a positive curve. However, the curve actually drawn is generally the (positive or negative) curve with an opening angle less than or equal to180 degrees.
Tangent Curve:
This option utilizes the advantage of the CURVE command to connect a curve tangentially to a preceding object. Here the preceding object is the line or curve drawn immediately prior to your current line or curve.
Back:
This option allows you to take any lines or curves drawn within a single prompt (!) of this function and delete them in reverse order.
End:
By choosing this option, or by clicking enter/return, you close the interactive drawing cycle.
