This cancels the second point and you are asked to supply the starting point again. You are than asked to "Specify next point." Right click. You are asked to "Specify first point." Click on the current object at your given location (end point, mid point.). Assume that you already have an object on the screen. In this example I will use the 2 Points line command. If you are wanting to start drawing an object a certain distance away from an existing object it is easily accomplished. Scroll towards the bottom of the thread I have linked to below and read my description of the Snap icons. If using an absolute address then a point on a line makes no difference: 0,0 is absolute regardless of any point in the drawing. From there you can use relative addressing to specify a location. As an example, you can turn on Snap to End and the cursor will snap to an endpoint of the closest entity. It is quite powerful and potential in this sector and have capabilities to gene. An entity can be a line, rectangle, circle, etc. LibreCAD is a Free, Open Source Computer aided Drawing and Drafting Software.
My previous experience in CAD was with the old Draft Choice program, so Im presuming I have some holdover misconceptions.
The point can be an end point, a middle point, a center point and so on. Greetings, Im (obviously) new to LibreCad, so I have some basic misunderstandings in drawing simple objects with which I need help. Snaps are just what the name implies: snap the cursor to a point on an entity. I'm not sure what you mean when you say, "My issue, right now, is how do I select a specific point from a line, polyline, rectangle, etc." What throws me is the word "from a line." If you mean "on a line" then using a Snap will be the most accurate.
