How can i control the extrude size of a curve while creating it? i need to make a sightly smaller subdivission on my curve because i need to reach a part of the 3D enviroment without having to move the object, so i use extrude (pressing E) but the curve created is too long and the shape is lost.
Is there any way i can control the curve size while pressing E?
When creating a curve you have some control using the parameters on the tool bar (press T to make it visible) or revel the tool options bypressing F6



Once a Curve has been created it can be manipulated with precision using the Transform control panels. (Press N to make it visible)
