This app reads your drawing, and finds and pairs 2 types of objects:

1st: Polyline to calculate area or length. Circle is also supported

2nd: Tag block: contains attributes to show polyline area value. If a tag block is placed inside a polyline, they are a pair.

In case your want to pair a tag block that are not placed inside a polyline, you should use a leader to connect them, as seen in screenshot.

Then, it populates all polylines's area values to specified attributes in their paired tag blocks.

So, to streamline the workflow, firstly, you have to set up your drawing properly:

+ Polylines to calculate areas should be on specific layers.

+ If not yet exist, you have to create a Tag block with attributes to store the polyline's area values using the Autodesk® AutoCAD® BLOCK command.

+ For each polyline, add a tag block within or connected with a leader. Leaders should be placed in specific layers.

Once everything is set up, you can start using this 7cad Polyline Area Online app:

1. Upload your drawing.

2. Fill in all relevant fields in the form, then click Summit.

Finally, you can sit back waiting for the result drawing to be returned soon in about a minute. Enjoy!
