Rectangle 3 Points- Center / Corners


This topic will explain the Rectangle 3 Points - Center / Corners function,will explain where to find the function, and explain the options foundin it.This topic will also give a brief description of Dynamic Drawing,the Snap Increment function, explain creation with quick steps, and providelinks to related topics.

The Rectangle 3 Points - Center / Corners Function

The Rectangle 3 Points - Center / Corners function is used to createrectangles using sketching, data entry, or a combination of both.

Dynamic Drawing

This function supports Dynamic Drawing which allows you to use a combination of sketching and data entry to create the entities. Prior to confirming the desired result in the function, an adjustable preview is visible. These previews can be modified using data entry. The benefit of Dynamic Drawing is that you can quickly place and adjust the size to get the approximate result, and then use data entry to update to the exact dimensions, and coordinate values as needed.

Final Entities


In the images above, we see the preview of surfaces which can still be adjusted, followed by those same surfaces after they are finalized.

Snap Increment

This function support the use of the snap increment when selecting the location of the entities. The snap increment allows you to get precise results when using mouse selection and helps to reduce data entry modifications.

To use the Rectangle 3 Points - Center/Corners creation option, for the Rectangular Plane:

  • In the Surfaces group, of the Create 3D ribbon,click the down arrow under Planar, and select Rectangular Plane.

    Once in the feature, select the Rectangle 3 Points - Center/Corners Creation Option.

The parameters display in the Data Entry Manager.

The Data Entry Parameters

Creation Options




  • Length (X) - sets the length of the rectangle along the X-axis of the Active UCS.
  • Width (Y) - sets the width of the rectangle along the Y-axis of the Active UCS.
  • Angle - allows the rectangle to be rotated around the origin.



Base Point

The Base Point determines the coordinate location of the rectangle using the XYZ coordinates of the active UCS. The selected origin location determines where the origin is on the entity.


  • X - is the X-axis location of the entity origin.

  • Y - is the Y-axis location of the entity origin.

  • Z - is the Z-axis location of the entity origin.


Tip: The XYZ coordinates are in reference to the active UCS, or user coordinate system.



Corner Type


  • Sharp Corner - creates the rectangle with sharp corners.

  • Radius - creates the rectangle with round corners using the Radius value.

  • Chamfer Length - creates the rectangle with chamfered corners using the Chamfer value.



  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps

Dynamic Drawing Method

  1. Open the function and choose the Rectangle 3 Points - Center / Corners Creation Option.

  2. Click a snap point or anywhere in the graphics areato set the center point of the rectangle.

    You can modify the snap incrementvalue or turn it off while selecting locations with the mouse.

  3. Movethe mouse pointer and click a snap point or anywhere to set the lengthof the rectangle.

  4. Movethe mouse pointer and click a snap point or anywhere to set the widthof the rectangle.

    This is now the active entity, whichmeans that it is not fully defined.

  5. Dynamic Drawing allows you to update the Data Entryparameters to modify the active rectangle.

    After updating the Data Entry parameters, to finish the active entity,you can click OK or startsketching the next rectangle.

    When you don't need to update the Data Entry parameters, you can justclick to start the next rectangle.

    In the images above we see the finished surface and the finished surface with the point used to create it.

Note: Thereare many ways to finish the active entity: click OK, press Spacebar, orclick in the graphics area to start the next rectangle.

  1. Repeat this process for all rectangles to be created.

  2. To close the function, click Cancel.
