Introduction

Note: Before starting a CAD modeling all images should be oriented and the project should be scaled.

Basic CAD shapes (including point, polyline, rectangle and circle) can be drawn on image by the using the following tools at the toolbar of Image View:

Basic CAD shapes


Note: If Point Cloud of the object is available (see Point Cloud Generation) enabling Auto Pan Image assists the CAD modeling by automated image pan and image measurement. This results in principal CAD modeling or image measurement by working on only one image:


This results in principal CAD modeling or image measurement by working on only one image

A second image should be opened in Image View and the measurements should be supervised for a case of wrong image measurement error.


Note: CAD modeling will work only with image points which have 3D coordinates. For example, drawing a line requires two image points which have 3D coordinates.


Drawing Image Points

There are two type of image point measurement: automatic or manual.

Automated

This mode is suitable for the semi-automated measurement of circular closed shape targets. Drawing mode can be switched to automated point drawing if “Draw automatic point” is selected:

By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the label of the image point:


By pressing <Alt> key the following mouse cursor will be displayed


The label can be set by changing the prefix and the counter boxes in the toolbar. For example, in the above example the prefix is B and the counter was set to 15. Therefore, the label of the image point is “B15”.


Note: Note:
  • By holding the <Alt> key and right click the counter will be increased.
  • It should be noted that the label should be unique in each image. Points with labels already existing in the image are not accepted.


By clicking only near the round shape target, the target center will be measured automatically. The following figure shows the position that the mouse has been clicked and the measured target center and the label.

Manual

This mode is suitable for the fully manual measurement of any feature. Drawing mode can be switched to manual point drawing if “Draw manual point” is selected:


Drawing mode can be switched to manual point drawing if “Draw manual point” is selected


By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the label of the image point:

By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the label of the image point


The label can be set by changing the prefix and the counter boxes in the toolbar. For example, in the above example the prefix is M and the counter was set to 14. Therefore, the label of the image point is “M14”.


Note:
  • By holding the <Alt> key and right click the counter will be increased.
  • It should be noted that the label should be unique in each image. Points with labels already existing in the image are not accepted.


By right clicking on any feature, a point will be added to the image point.


Drawing Circle

Drawing mode can be switched to drawing circle if “Draw a Circle …” is selected:

Draw a Circle


By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing.

By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing.


Drawing a circle requires the measurement of three 3D images points. Therefore, when you pick up the image points, those points should have 3D coordinates. Image points with 3D coordinates are shown with diamond icon:

Drawing Rectangle

Drawing mode can be switched to drawing circle if “Draw a Rect …” is selected:

Drawing Rectangle


By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing:

Drawing Line

Drawing mode can be switched to drawing Line if “Draw a Line …” is selected:

Drawing Line


By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing.

By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing.


Drawing a line requires the measurement of two 3D images points. Therefore, when you pick up the image points, those points should have 3D coordinates.

Drawing Polyline

Drawing mode can be switched to drawing Line if “Draw a Polyline …” is selected:

Drawing Polyline


By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing.

By pressing <Alt> key the following mouse cursor will be displayed. The box at right bottom of the cursor indicates the current step of drawing.


Drawing a polyline requires the measurement of two 3D images points. Therefore, when you pick up the image points, those points should have 3D coordinates.
