Editing mass elements

Editing Mass Elements

  • Trim by Plane-MassElementTrim

  • Split by Plane –

    MassElementDivide

  • Split Face –

    MassElementFaceDivide

  • Join Faces–

    MassElementFaceJoin


Accessing trim masselementtrim

Accessing Trim (MassElementTrim)

Command prompt:

MassElementTrim

Select a mass element and choose Trim by Plane from the Modify panel

The command (MassElementTrim) creates a trim plane that cuts across the element.

You can then select which side of the trim plane to retain.


Trimming a mass element

Trimming a Mass Element

  • (Select a mass element and choose Trim by Plane from the Modify panel.)

  • Specify trim plane start point or [3points]: (Select p1 using endpoint object snap as shown below.)

  • Specify trim plane end point: (Select p2 using endpoint object snap as shown below.)

  • Select mass element side to remove: (Select p3 using endpoint object snap as shown below.)


Accessing split by plane masselementdivide

Accessing Split by Plane(MassElementDivide)

  • Select the mass element, right-click, and choose Split by Plane

  • The Split by Plane command (MassElementDivide) creates a cutting plane that cuts the mass element.


Splitting mass elements

Splitting Mass Elements

  • Select the mass element and choose Split by Plane from the Modify panel.

  • Specify divide plane start point or [3points]: (Select point p1.)

  • Specify divide plane end point: _mid of (Select point p2.)


Accessing split face masselementfacedivide

Accessing Split Face(MassElementFaceDivide)

(Select the mass element and choose Split Face from the Modify panel.)

Select first point on face: _mid of (Select point p1.)

Select second point on the same face: _mid of (Select point p2.)

Gable converted to Free Form.

Select first point on face: ~EnterKey~ (Press the ~EnterKey~ to end the command.)

Note: The face at p3 was stretched after the split.


Creating groups for mass elements

Creating Groups for Mass Elements

  • Complex models are created by defining a group and attaching elements to the group.

  • The Mass Group tool inserts a group marker, the group marker represents the group.

  • Mass elements are attached to the group after the group marker is established.


Accessing the mass group tool

Accessing the Mass Group Tool

  • Command prompt: MassGroupAdd

  • Select the Mass Group tool from the Massing tool palette


Creating a mass group

Creating a Mass Group

(Select Mass Group from the Massing palette.)

Select elements to attach:(Select a mass element.)

Location: (Select a location in the workspace.)

Attaching elements...

1 element(s) attached


Accessing mass group attach command

Accessing Mass Group Attach Command

Select any member of a mass group to display the mass group marker shown at right, right-click and choose Attach Elements.

Respond to the workspace prompts to select additional mass elements.

Boolean operations with mass elements

Boolean Operations with Mass Elements

Mass Elements that are attached to a group can be defined to add, subtract, or intersect their mass with the other elements.

If a mass group exists in the drawing, the mass group and operation can be specified in the Properties palette when new elements are added.

After a mass element becomes a member of a group all elements of the group and the group marker are displayed.

To isolate and edit a mass element that belongs to a group select the Edit in Place grip. The Edit in Place toggle turns off the display of the group and allows you to edit mass elements.

  • Union

  • Subtract

  • Intersect

Creating floor plate slices of mass elements

Creating Floor Plate Slices of Mass Elements

  • After you develop a mass model of a building, you can create a floor plan from the model

  • The Slice command (AecSliceCreate), located on the Massing tool palette, allows you to slice through the model at elevations equivalent to floor elevations.

  • The AecSliceToPline command, accessed from the shortcut menu of the slice, can convert the slice to a polyline.

  • The polyline can be converted to walls (right click a wall tool >Apply Tool Properties to>Linework).


Accessing the slice command

Accessing the Slice Command

  • Select Slice from the Massing tool palette


Applying the slice command

Applying the Slice Command

(Select Slice from the Massing tool palette.)

Number of slices <1>: 2 enter

First corner: (Select a point near point P1 shown at right.)

Second Corner or [Width]: (Select a point near point P2 shown at right.)

Rotation <0.00>: enter (Press enter to accept the 0° rotation.)

Starting height <0”>: 3’ enter

Distance between slices <1’-0”>: 9’ enter

(Slice markers are created for each of the slices, as shown at right.)


Attaching objects to a slice

Attaching Objects to a Slice

  • The Attach Objects command (AecSliceAttach) is used to assign the objects to be sliced.

  • Select a slice marker, right-click and choose Attach Objects


Accessing convert to polyline

Accessing Convert to Polyline

  • To convert the results of the slice to polyline

  • Select a slice, right-click and choose Convert to Polyline
