How to use iCMTGIS PRO to extend a line beyond its end points?

“I have managed to join two nodes and get a straight shape line between them, but how do I do to extend the line on the outside of the nodes?”

There are a few ways to achieve this. Here is a quick way (but not precise): Tap on the existing straight line then select the Insert Node function on the Tools menu. Move the circular Node Tool to the end point of the existing straight line. Tap in the center of the Node Tool. Select “After” then tap on Next step. Now move the Node Tool to a new position, eyeballing the proper bearing, then tap in the center of the Node tool to add the new node. To extend the line in the other direction, select the start point of the line and select “Before” for inserting the new node.

A precise way is as follows: After you have created the initial line based on two existing points, tap on it then select View Deed Calls. Tap on the Calls tab then tap on Edit.

Increase the horizontal distance then tap the Back button.

Confirm to update the Feature. You will see that the Line Feature has been extended in one direction.

Now use the end nodes of the elongated line to create another line in the opposite direction. It will have a different Line ID. You can turn on Sheet View to see the two line records. Select the new line and use the View Deed Calls function to change the distance value. Confirm to update the Feature.

If you don’t confirm to update the Feature, then no change will be made to the original line.

I would create a new Topic (named “Long Line”, for example) into which to put the final long line. This will help reduce confusion when you are staking out in the field. Have this new Topic active and select the correct line when you are doing the Line Stakeout. (You could also delete all the other lines that you will not be using for stakeout.)
