5 In this grid, you can set all the different types of materials that you are going to use in IMPACT. The technical data you can set is "Density", how the material will look like when rendered ("Material Type"), Weight" and how the material will look like when shaded ("R", "G" and "B").

10
11 The mass of an element is calculated with the volume multiplied by the density.

19 //Figure 3: You can get an elements mass by holding the mouse pointer on the element//
20
21
22 The weight of an element is multiplied as the volume multiplied by the weight.
23
24 You cannot insert the weight in the drawing head but, it’s possible to present it in a report.
25
26 == Color ==
27
28 It is possible to set how a material will appear, both when rendered and shaded.

32 //Figure 4: Rendered and shaded appearance //
33
34 To set the shaded color to a material, you need to choose a color and get the values for red, green and blue (RGB-value). Insert the RGB in the columns "R", "G" and "B".
35
36 == Hatch pattern ==
37
38 (% class="wikigeneratedid" id="H" %)
39 It is possible to define custom hatch patterns for materials in IMPACT. The pattern will be drawn on shop drawings where the material is presented. First, find the pattern you want to use by starting the hatch command in AutoCAD, as shown in the animation below...
40
41 //[[image:select_hatch_pattern.gif]]Figure 5: Hatch pattern command in AutoCAD//
42
43 Next, you'd want to find and open the file named// acad.pat// . This file contains all browseable hatch patterns in AutoCAD...
44

46
47 //Figure 6: Pattern file where the hatch patterns in Autocad are listed//
48
49 Open the file and find the pattern you want to use, in this example we will use the //Honeycomb pattern//.
50
51 [[image:Honey.gif]]
52
53 //Figure 7: File where hatch patterns are listed//
54
55 Copy the marked text into a new text file. Change the information in the top line from **//*Honey, Honeycomb pattern//** to match the name of the material that you want to use the pattern with. In this example, we'll change the text to //***Polystyrene, Polystyrene pattern**//. The material in IMPACT Standard Admin is named Polystyrene.
56

58
59 //Figure 8: Edit information in the text file//
60
61 **NOTE:** A blank line must be placed after the last hatch pattern definition in a PAT file. If a blank line is not placed after the last hatch pattern definition, the last hatch pattern definition will not be accessible when creating a hatch fill.
62
63 Save the file to the standard directory. In this case it's: …common\1100\1100\templates_drawings.
64
65 It is important that the name of the hatch pattern is the same as the name of the material one wants to use it for.
66
67 == Hatch patterns to download ==
68
69 We have some predefined hatch pattern example that can be downloaded using the links below. There is also a preview of the pattern below the link.

83 == Change the scale of a filling hatch ==
84
85 If you have a wall and add a filling to it with a hatch, it will automatically get the same scale as the drawing itself. The scale can then be changed on 3 levels, the drawing itself, local or common.
86
87 On the drawing, you double-click on the hatch and change the scale there. ​​​​​​​The scale was 30 on the drawing.
88
89 [[image:Asdefaultdrawingscale1.png]]
90
91 //Figure 11: Hatch scale 30//
92
93 The local and common settings are changed in standard admin under variables. The variable is beginning by the material you choose e.g. LAC. The variable for LAC will then be **LAC_FILLING_SCALE**. There you can set the scale under //Value.//
94

96
97 //Figure 12: Standard Admin variables//
98
99 Next, you return to the drawing and refresh the settings, //Base// -> //Refresh settings and properties.//
100
101 [[image:refreshafterchange3.png]]
102
103 //Figure 13: Refresh settings and properties//
104
105 Lastly, you redraw the drawing and the adjusted scale is set,// Element -> Draw Element. //
106

108
109 //Figure 14: Draw Element//
110
111 The result should look like this.
