# Ecotect Tutorial : Nudging Objects

### Synopsis

Nudging is an incredibly useful way of working with geometry in Ecotect. Using nudge allows you to incrementally adjust the size, shape and position of objects in relation to the x, y and z axes in the 3D editor window. This tutorial demonstrates a number of different ways in which you can use nudge to modify geometry in an Ecotect model.

##### Duration

You will need about 15 minutes to complete this tutorial.

##### Training and Accreditation

Successfully completing this tutorial fulfills one of the practical skills required for completing Level 1 of the Geometric Modelling training module.

##### Resources Required

To complete this tutorial, create a new Ecotect file containing one zone with the following dimensions - 6000 long x 4000 wide x 2400 high. Alternatively, download the example file at the end of this tutorial.

### Tutorial

Nudging Basics

1. It's really simple to nudge an object in Ecotect. First, select the object, and then use the x, y and z keys on the keyboard to move the selection along the x, y and z axes respectively.
2. Pressing the x, y and z keys by themselves move selected objects in a positive direction along the relevant axis. Holding down Shift in conjunction with the x, y and z keys moves the selection objects in a negative direction. You can determine the positive direct of each axis anytime by simply rotating the 3D view. The X, Y and Z axis will be displayed as you interactively rotate.
3. The nudge increment is the same as the current snap grid setting set in the Options toolbar. Change this value to control how far an object moves with each nudge.
4. The progressive amount of nudge is shown in the Status Bar at the bottom of the main application window.

Let's now take a look at how nudging can be used to move and modify geometry in an Ecotect model.

Moving entire objects

1. Select the entire zone.
2. Use nudge to move the entire zone around the XY plane, or up and down along the Z axis.

Reducing the height of an entire zone

1. Select the entire zone.
2. Press the F3 key to enter node editing mode.
3. Select all of the nodes along the top of the selected zone as shown in the screenshot.
4. Use the z nudge to increase or decrease the overall height of the zone.

Stretching the length or wide of an entire zone

1. Select the entire zone.
2. Press the F3 key to enter node editing mode.
3. Select all of the nodes along the edge and face of the zone as shown in the screenshot.
4. Use the x nudge to increase or decrease the overall length of the zone.
5. To change the width, select the required edge and face of the zone and use the y nudge accordingly.

Creating a raked ceiling/skillion roof

1. Select the entire zone.
2. Press the F3 key to enter node editing mode.
3. Select just the top edge nodes as shown in the screenshot.
4. Use the z nudge to create the required skillion/rake height.

Nudge can also be used to move and modify child objects such as door and windows. As you can see, nudge is a quick and easy way to work with geometry in a Ecotect model, especially in the early stages of creating a model.

Reducing the height of an entire zone or Stretching the length or wide of an entire zone doesn't work on my machine, I'm using a parrallels desktop on a Mac
