Join lines
-
The curves in my model are made up of lots of small lines where they should in fact be one whole line.
Is there a plugin or tool to combine the small lines into one line? -
Look for a ruby script called WELD. It will do what you are after.

I have been trying to use Weld however it keeps crashing sketchup when i use it.

You could overlay the trajectory with either a polyline or a bezier curve maybe and adjust the segments. Just an idea, assuming you need the whole curve to act as a single unit.

Make sure the selected edges could actually become a curve - that means no branching and no gaps...

hi,
I've been trying to figure out the best way to create a polyline (so 'pushpulling' shape into a 3d form as such without the unnecessary and unaesthetic lines) is to create the shape with the lines/curves necessary and then select all the bounding lines around the 2d shape and select the weld option to create a polyline and join all the bounding lines of the shape together.
The problem i seem to be having is that like in the example i've attached below i'd like the line at the point of the 2d shape when extruded into a 3 shape to stay and not disappear when turned into a polyline.
To do that you'd need a 'break polyline at point' option like there is on autocad if my memory serves me correctly, however when i tried mimicking this with adding a line at the point that i want to break, it breaks up another point in the polyline and creates two separate polylines instead of the one polyline with a break point (with no gaps)
can anyone help me in sorting this out

I am assuming you mean a line on the ground plane. You would like this line to appear at the top of the extruded "teardrops". If this is the case, you merely have to select the line or lines, and use Move tool with Control to copy up to the top.
Sorry if I have misunderstood. -
I think what you want to do is to pushpull a line...
You can't - pushpull extrudes faces only - SUp doesn't natively do that to edges.
However, there are several scripts / tools - e.g. see my ExtrudeEdgesByVector - it allows you to pick line[s] and then start/end-points to set a vector, and it'll extrude into face to match...
It will still have a back and front as it's a 'one sided' face...
If you want a thin 'blade' with two external faces then you need to make a thin tapering face on the ground and then pushpull that up into 3D...

Sorry if i was unclear - I mean a break point in bounding lines of a closed 2d shape but with no gap. a bit like the following example in autocad - http://www.cadtutor.net/tutorials/autocad/modifying-objects.php (scroll down to 'The Break Command' but instead of P1 and P2 being two different points or coordinates on the 2d shape outline/polyline they are the same point (P1=P2).
Though as after looking it up on the net i couldn't find an exact example of what i was looking for, perhaps it's not possible.
hope that makes more sense and thanks for helping!
