Sketch Editing: join points and continue line/spline line from last end point

[kevinwatts]

When editing a sketch, I would need to know:

1) How to join end Points of two separate lines/T-spline lines?

2) How to  extend or continue drawing from a line end Point?

3) How to duplicate a sketch to another sketch layer?

Need detailed explanation or video tutorial. Thank you.

Thanks for posting, and welcome Fusion360!

I think I can answer your questions.

1) How to join end Points of two separate lines/T-spline lines?

I can answer this for sketch lines:  Use the Coincident constraint, and select the endpoints of the two lines, or any sketch curve.  You can do this by either pre-selecting the two endpoints and choosing Coincident, or by selecting Coincident first, then selecting the endpoints after.  Here is a screencast of this:  http://autode.sk/1PdqMP7

I'm not sure exactly what you mean by joining the endpoints of T-spline lines.  Can you show an example?

2) How to  extend or continue drawing from a line end Point?

There is an Extend command in sketch:  http://autode.sk/1CsYBBA

To continue drawing a new line, just pick the line end point as the start point of a new line: http://autode.sk/1aE0HZW

3) How to duplicate a sketch to another sketch layer?

I assume that what you really want to do here is to copy geometry from one sketch to another sketch.  Copy/Paste can do that:  http://autode.sk/1Pds8cF

Hope this helps you make progress!

Thank you Jeff for the fast reply. It is appreciated!

Your approach is good. However, I did not want to move or modify the two lines/curves being joined which can happen when using the Coincident constraint. I also wanted to control which Sketch Layer I can place sketches. Here are my ruff notes on what seemed to worked for me.

JOIN 2 SEPARATE LINES (WITHOUT AFFECTING THE EXISTING LINES)
1. Select and make visible the target Sketch Layer
2. Hold down CTRL (windows), and select SKETCH → LINE
3. To connect with a straight line:
       Select the end point of the first line/curve
       Then select the End Point of the second line/curve
4. To connect with a curved line:
        Select the end point of the first line/curve,
        Hold L-Click and drag to select the End Point of the second line/curve
The line segments are separate but the Points are locked together.

COPY SKETCH (to another Sketch layer)
1. Select all elements of the SKETCH to be copied.
2. R-CLICK → COPY
3. Deselect
4. Hide Sketch Layer
5. Create or Highlight a target layer
6. R-CLICK → EDIT SKETCH
7. R-CLICK → PASTE (the contents will be pasted to the same coordinates as the original)

This solution still ignores the fact that it still registers "to the click" as two separate sketches. Yes, you can make them coincident. Yes, you can make them tangent. Yes, you can make control lines coincident. Yes, they move and act as one.

But at the end of the day, it's still two separate points, and two separate control lines one over the other. It's kinda janky that there isn't a "merge Points" feature in "Edit Sketch" Mode.
