How to Add Connection Points Without Distorting Shapes in PowerPoint
Question details
The user needs a method to add custom connection points to a presentation shape without causing the geometric outline of the shape to warp or distort.

- Product
- PowerPoint
- Device & OS
- not provided
- Scenario
- Creating detailed flowcharts or diagrams where standard shape connection nodes are insufficient, requiring additional anchor points for connector lines.
- Observed behavior
- Using the native 'Edit Points' tool successfully adds new nodes but recalculates the shape's path, causing noticeable distortion to the original shape's outline.
Identify exactly how many extra connection points your diagram requires and verify that your slide elements are completely positioned before modifying the shape geometries.
Use a Transparent Duplicate Shape for Connection Points
Create an invisible duplicate of your shape to hold the extra edit points, then group it with your original, undistorted shape.
Select the original pristine shape on your slide and press Ctrl+D to create an exact duplicate.
Right-click the duplicated shape and choose 'Edit Points'. Add the required extra points along the border. Ignore any distortion that occurs to this duplicate shape.
With the distorted duplicate selected, go to the Shape Format tab. Set both the 'Shape Fill' and 'Shape Outline' options to 'No Fill' and 'No Outline'.
Drag the invisible duplicate so it sits exactly on top of your original shape. Select both shapes, right-click, and choose 'Group' (or press Ctrl+G). The invisible points will now act as connection nodes for the entire group.

Import an EMF File from a Dedicated Vector Program
Design the shape in a vector graphics tool like Inkscape or Adobe Illustrator, export it as an EMF file, and import it into your presentation.
Edit Shapes and Create Professional Diagrams with WPS Presentation
WPS Presentation offers intuitive shape manipulation and flawless compatibility with standard formats. You can effortlessly execute transparency overlays to build complex flowcharts without losing any formatting or visual fidelity.
- 1. Insert your base shape: Open WPS Presentation, navigate to the Insert tab, click on Shapes, and draw your primary diagram element on the slide.
- 2. Duplicate and edit: Select your shape, press Ctrl+D to duplicate it. Right-click the new shape, select 'Edit Points', and click along the path to add your new custom anchor points.
- 3. Apply transparency: Under the Drawing Tools tab, change the Shape Fill to 'No Fill' and Shape Outline to 'No Line' so the duplicated shape becomes completely invisible.
- 4. Align the shapes: Drag your invisible shape over the original one. Select both elements, go to Align, and choose 'Align Center' and 'Align Middle' to ensure perfect overlapping.
- 5. Group for final use: Right-click the selected shapes and click 'Group'. You can now attach standard connector lines to the custom points of the grouped object.

Frequently Asked Questions
Why does adding an edit point distort my PowerPoint shape?
Presentation software uses edit points to define the exact geometry and Bezier curves of a shape's path. Adding a new point forces the software to recalculate the tension and angles of the curves along that segment, which typically alters the shape's original outline.
Can I add connection points without ungrouping an imported EMF file?
No. When you first insert an EMF file, the software treats it as a single static picture block. Its internal vector anchor points will not function as connection nodes for your flowchart lines until the graphic is converted into a native drawing object by ungrouping it twice.
Will a grouped transparent shape affect how my flowchart connectors behave?
No, the transparent shape's edit points will successfully function as anchor nodes for your connectors. As long as the transparent shape is grouped with your primary shape, the connector lines will seamlessly snap to those invisible points without any issue.
What is an EMF file and why use it instead of PNG or SVG?
EMF (Enhanced Metafile) is a vector graphic format natively optimized for Microsoft Office and WPS Office. Unlike raster formats (like PNG), EMF files can be broken down (ungrouped) directly within the presentation software into fully editable native shapes, lines, and connection points.
