Please Help!!! - Rotate new Workplane along a default Axis With API

jpchaisson — Sat, 05 Nov 2011 19:09:37 GMT

How do you create a new Workplane from a Defualt Plane and rotate it along a default Axis?

I am new to API and trying to create workplanes and rotate them along a Axis.

Im trying to use "AddByPlaneAndOffset" is this the right method?

No, AddByPlaneAndOffset allows only a plane parallel to the source plane. Use SetByLinePlaneAndAngle instead.

can you show me a example of using that method?

ok i have it working, but my angle isnt coming out right. how do i set the angle as a Object?

Sorry, couldn't provide the example at work. Now at home I'm too late.

The angle, if provided as numeric value without dimension is interpreted as radiant !

From developers help:

Input Variant that defines the offset angle of the work plane from the input plane. This can be a numeric value or a string. The offset angle of a work plane is always defined by a parameter. When a new work plane is created, the parameter is automatically created. If a numeric value is supplied the new parameter is set to the value specified and the value is always in radians. If a string is supplied it is used as the expression for the newly created parameter and will be interpreted the same as if the user entered it in a dialog. This means if a value is specified without a unit qualifier it will default to the current document length unit. The following is a valid entry for the angle, assuming the parameter d2 already exists and defines an angle, 'd2 + 10 deg'. The positive angle direction is computed by crossing the axis vector with the plane normal vector.

thank you for responding, i think i understand what you are saying heres my code for a more visual.

Dim oPartDoc As PartDocument

Dim oPartCompDef As PartComponentDefinition

Dim BaseXY As WorkPlane

Dim AxisX As WorkAxis

Dim oANG1 As Double

oPartDoc = oApp.ActiveDocument

oPartCompDef = oPartDoc.ComponentDefinition

BaseXY = oPartCompDef.WorkPlanes.Item(3)

AxisX = oPartCompDef.WorkAxes.Item(1)

oANG1 = "30"

oPartCompDef.WorkPlanes.AddByLinePlaneAndAngle(AxisX, BaseXY, oANG1)

what am i doing wrong my workplane ends up being a 2.xxxxxxx deg angle???

Hello

Try

Dim oANG1 As String
oANG1 = "30 grd"

Your code means an angle of 30 radiant = 1718,8733853925°.

Thank you so much its working great now.

can you explain what the "grd" means ?

"grd" means just grad or degrees or ° and is the unit of angle value. Take a look at your fx-Parameters after creating your workplane and the new parameter for the angle.
