7cad Polyline

7cad Polyline

Win32 and 64, English

Some special commands to work with polylines.

General Usage Instructions

The app has a setup command names 7cadPolylineSetup. Run the command and a window opens up. On this window, you can restrict a command to work with a polyline in a specific layer. You can also see the app's license status. If already done, you can activate the license following on-screen instructions.


If you change the layer filter to "Road*", then when DIMPLINES runs, it will select polylines, 3d polylines in layer names start with "Road".


If you change the layer filter to "CLIP*", then when MOVEPLINES runs, it will select polylines and/or circles in layer names starting with "Clip".


This command is a little different. The layer filter doesn't affect the command directly. It is only when you want the STRETCHFILLETPLINES command embedded directly inside Autodesk® AutoCAD® built-in STRETCH command but restrict it to work on polylines in specific layers. For example, if you change the layer filter to "REBAR*", and run the STRETCH command, many polylines can be stretched. But only if it is a polyline in layer names "REBAR TOP" or "REBAR BOT", then the app will try to keep all its fillet corners.


Run the command and its specific options window brings up. Available options are: fillet radius, extrude to 3D pipe, pipe's dimensions, and layer.


If you purchase or start a trial period of the app via Autodesk Store, then the app will run without any restriction.

Otherwise, without a license, the app is for testing purposes only. It allows you to test in 30 AutoCAD sessions.

Ribbon/Toolbar Icon Command Command Description


Select 2D Polylines or 3D Polylines and the app will draw dimensions on each segment.


Select 3D Polylines to fillet at specified radius, then extrude it to 3D pipe.


Firstly, this command performs the built-in STRETCH command. Then, if a selected object is a 2D polyline with fillet corners, then the app will try to keep those fillet corners with the same radius if possible.

Select polylines and move them with all the objects inside.


Setup layer filters for each command. Enable or Disable the StretchFilletPlines to embedded directly in the build-in STRETCH command of AutoCAD. Activate the app's license.
