Question:After using flatten command in CAD,spline can be changed into short polyline.How can it make the length stay the same with the changing attribute?
Answer: Spline and polyline is different type of object in ACAD.And the generating way is different.It is difficult to get exactly the same length before and after conversion. We usually use polyline to simulate spline in order to make precision match engineering applications.
This simulation is transformation. The length difference before and after conversion can be very small and discrete degree can be very low.
Question:How to change spline into polyline?
Answer: Type the command: flatte in the command line. Follow the prompts to select the spline you want to convert.
Note: flatten command belongs to Express Expansion Kit commands. Before using make sure you have installed this extension tools.
