Drawing A Perpendicular Line

Technical Support Basics & Interface
1

Hello Blender People:

Okay… this may be a slightly cheesy way to ask my question, but it’s all I can think of at the moment, and it makes a lot of sense…

Look at the following (very short) animated gif…

What I am trying to do is draw a line from A to B that is perpendicular to line CD… Line CD does not have a vertice in it - though it will need one because my ultimate goal is to make two faces out of the end product…

I hope this makes sense… It was the easiest way I could think of to explain what I am trying to do…

Any help much appreciated.

Thanks…

This is very simple.

1.Subdivide line C-D ( To do that just select it, press W and choose “Subdivide”)
2. select vertex you have created, and press N for it’s properties - change X position to same value A point has. ( to check position of A point you select it and press N)

I hope that is the answer.

Easy.

  1. In edit mode, select CD and subdivide to create a vertex.
  2. Select A, press N for Transform Properties. Check the Vertex X parameter.
  3. Select B, edit its Vertex X parameter to match that of A.

Subdivide your CD line: select the edge, W > Subdivide. Adjust the position of this new vertex (the centre of CD) with G > X (so it will remains on the X axis). Select both A and B vertices and press the F key.

Another way, more precise: after the subdivision, press the N key, you’ll see the Propriety Panel on the 3D window. Select your vertex A, copy its Vertex X value and paste it on the Vertex X value of the B. Press F to make the edge.

Edit: Ok I’m very slow to answer.

Or, using snap. First enable snap,set it to closest, then after subdividing, move B with G > X, and hold ctrl and click on A.

Ty, Everyone.

The “numeric” and “snap” responses were most helpful.

Just another quick question about the numeric pad. I know Blender measures objects in terms of “Blender Units”, but is there any kind of ruler system one can set the interface to display?
