Joining straight lines to curves

danielchaboya — Wed, 19 Jun 2013 15:15:18 GMT

Is it possible to join a straight line to a curve? Using the trace tool to perform a join, the straight line segment joins to the two nodes of the curved line segment. What I need to happen is for only a portion of the line to join with the entire arc of the curve (be coincident). What options are available to do this.

Some approaches that come to mind:

1. Segment the line and draw the curve.
2. Redraw the parcel (I would prefer not to do this)

Any tips or tricks are greatly appreciated.

See attached image for an example.

Sadly, my experience tells me, you are stuck redrawing the parcel. Your first option might work. But if you go to do a LSA, its likely to blow up on you. That has been my experience.

If I understand your need correctly, then the method we use to correct these gaps is as follows:

Start editing that layer.

Select the poly on the right.

Edit the vertices of the poly on the right, adding a vertex at each point of coincidence with the neighboring poly, if a vertex does not already exist.

Finish the sketch.

Reshape the poly on the right, using the Trace tool, the End Point Arc Segment tool, or the Arc Segment tool available on the Editor and Feature Construction Toolbar.

Finish the sketch.

Run topology checks as needed.

Unless the geometry is corrupr or it is deliberately part of your prescribed workflow, there is generally no real need to recapture the entire polygon.

I'm probably misunderstanding what you want, but is it to make the rectangular poly be coincident with the curveed poly between the two curved poly vertices? If that's the case, you can select the rectangle poly, click the Reshape Feature tool, then the Trace tool, then trace the curved polygon from vertex to vertex. See Help here. (Note that the image on that page refers to the additional instructions, not steps 1 - 7). If you get a Failed to Reshape message, it's almost always because your polys don't actually touch at the vertex. They may be a very small distance away, or overlap and not meet at the vertex.

Sorry guys, I failed to mention that I'm managing parcels in a Pacel Fabric. The tools from the Editor toolbar cannot be used when editing parcels in a parcel fabric.
