This sketchup tutorial will teach you how to use the inference lock technique and show a few examples of inference locking in use and the advantages it has for modeling and navigating the sketchup viewport.
Roof inference locking sketchup.
As a follow up video to inference locking this google sketchup tutorial shows how to combine a series of roof forms together using inference locking.
Hold down the shift key to lock the inference you see.
This signifies that the image has been locked.
For example when the line tool cursor is hovering over the midpoint of another line the inference engine tells you by displaying a light blue dot and screentip that says midpoint as shown here.
Click where you want the edge to end.
Release shift to unlock the inference.
Once you do notice the blue box around it turns to red.
The edge gets thicker to let you know it s locked and now you can draw only in the blue direction no matter where you move your cursor.
Finding and locking an inference sketchup has an inference engine that helps you work in 3d space.
Another reason to lock an inference is to maintain one drawing direction while you reference geometry from another part of the model.
The edge gets thicker to let you know it s locked and now you can draw only in the blue direction no matter where you move the cursor.
Lock the illustration next to it as well.
I m on a mac with sketchup 15 3 329 this is what i am reading on the sketchup database locking inferences with a keyboard by locking inferences you can confidently draw along the direction you intend to draw.
Click the peak of the roof to make your vertical edge end at exactly that height.
You will also use arrays and copying to create dormers.
Hold down the shift key to lock the inference you see.
Inference locking is the ability to draw or move in only one locked direction in sketchup.
It is a key skill for fast and efficient sketchup use.
Inference locking is the ability to draw or move in only one direction and still reference other geometry.
