Drawing Element Properties
The Drawing Element Properties dialog box allows the user to define various elements and their properties on the drawing layer, style the border associated with the element, change the image’s transparency, change the current CRS (coordinate reference system) of the project and automatically apply the transformation scale factor on any particular layer to accurately map it to the project CRS.
Follow the steps given below to open the Drawing Element Properties dialog box:
- In the Map Data Layers panel, click on the […] button next to Default Drawing Layer.
- The Drawing Element Properties dialog box will be displayed.
The Drawing Element Properties dialog box contains three tabs as described below:
- General Options
- Spatial Reference
- Transformation
General Options
Various sections of the General Options tab are described below:
- Point Stylization
This section is used to define the shape, size, border color, and fill color of the point objects on the drawing layer. - Polyline Stylization
This section is used to define the color, width, style, and transparency of the polylines that will depict the boundary of the elements. - Polygon Border Stylization
This section is associated with the border of the polygon on the drawing layer. It allows the user to set its color, width, style, and transparency. Note that the Polygon Border Stylization checkbox is selected by default. - Polygon Fill Stylization
This section is used to define the fill color and the transparency of the image so that you can see through the image to the background Base Map. A transparency value of 40 to 50% works well. Note that the Polygon Fill Stylization checkbox is selected by default. - Assign Elevations
This section is used to assign elevation to elements on the drawing layer. The following options are available:- Drape onto terrain: On selecting this option, elements on the drawing layer appear to drape onto the surface terrain representing the ground surface. Note that this radio button section is selected by default.
- Float above terrain: On selecting this option and viewing in 3D mode, the user can drag the selected element vertically up and down by holding down the shift key.
- Assign elevation: On selecting this option, the user can assign a fixed elevation to the selected element on the drawing layer. The user can enter the elevation value in the entry field next to this radio button option.
Spatial Reference
The Spatial Reference tab allows the user to manually assign the project’s CRS to the non-CRS referenced data layer if the data layer coordinates lie within the project’s CRS. Refer to this article in our knowledge base to learn more about spatial reference.
Transformation
The Transformation tab allows the user to automatically apply the transformation scale factor to any particular layer and accurately map it to the project coordinate reference system (CRS). Refer to this article in our knowledge base to learn more about layer transformation.
