Use the tabs in this part of the dialog to define the following parameters:
- Dimension format - as for single parts
- Overall - the option operates identically as in the case of single parts
- Part spacing - these dimensions display mutual position of the assembly component parts. The dimensions are shown on external dimension lines (vertical or horizontal), and are generated parallel to the overall dimension lines. The following options are available:
- Contour
- Dimensions along the main axis (horizontal dimensions) - beginning and end of a subpart is projected onto the direction parallel to the axis of the element's main part
- Dimensions transverse with respect to the axis (vertical dimensions) - beginning and end of a subpart is projected onto the direction parallel to the specified direction of dimensioning, and the reference point should also be projected on this line. If any of these dimension points is positioned on one of the edges of the main part, parallel to the axis of the main part, this point is not dimensioned; a given part is projected on the dimension chain positioned on this side where the edge closer to the dimensioned part is located.
- Axes
- Dimensions along the main axis (horizontal dimensions) - the point of intersection of the element axis and the main part's edge, parallel to the axis and the closest to the geometrical center of the dimensioned subpart.
- Dimensions transverse with respect to the axis (vertical dimensions) - significant only for elements whose axis is parallel to the axis of the main element (the axis is projected onto the direction perpendicular to it). A dimension is placed on the vertical dimension line; if the axis of a dimensioned subpart coincides with the axis of the main part, then the dimension is not generated.
- Point
- Dimensions along the main axis (horizontal dimensions) - one of the edge points of a subpart is projected onto the direction parallel to the main part's axis (a point positioned closer to the main part's edge is selected). If both edge points of a subpart are located on the main part's edge, the point closer to the reference point is dimensioned.
- Dimensions transverse with respect to the axis (vertical dimensions) - the first (counting from the reference point) point met on the subpart's edge is projected onto the direction parallel to the specified direction of dimensioning. The reference point should be projected onto this line, as well; if any of these dimension points is positioned on one of the edges of the main part, parallel to the main part's axis, this point is not dimensioned. A given part is projected on the dimension chain positioned on this side where the edge closer to the dimensioned part is located.
- Optimal
- Dimensions along the main axis (horizontal dimensions) - selection depends on a subpart type
Plates perpendicular to the main part's axis, set orthogonally - the axes option
Plates perpendicular to the main part's axis, set slanting - the point option
Plates parallel to the main part's axis - the contour option
Profiles perpendicular to the main part's axis - the point option
Profiles parallel to the main part's axis - the contour option
- Dimensions transverse with respect to the axis (vertical dimensions) - selection depends on a subpart type:
Plates perpendicular to the main part's axis, set orthogonally - the point option
Plates perpendicular to the main part's axis, set slanting - the point option
Plates parallel to the main part's axis - the contour option
Profiles perpendicular to the main part's axis - the contour option
Profiles parallel to the main part's axis - the contour option
Additionally, the following options are accessible (they parametrize the position of a dimension line):
With overall - dimension lines are always placed on the same side as overall dimension lines. If the position of overall dimensions is not defined, lines are positioned according to the Optimal option.
Optimal - dimension lines are placed on the element side that is closer to a greater number of dimension points.
- Part dimensions - used to display only overall dimensions of subparts; dimensions are generated following the same rules as in case of the whole assembly. These lines are always generated as internal dimension lines, the orientation of which is determined in the local coordinate system of a dimensioned subpart or in the coordinate system of the main part of an assembly depending on the settings: part CS (Coordinate System) or assembly CS. If any of the dimensions generated by the algorithm is already shown on the external dimension line as an overall dimension, then it is not repeated.
- Openings in view - used for dimensioning of opening positions with respect to the element's main part. Dimensions in the direction parallel to the main axis are placed on the external dimension line, whereas transverse dimensions are positioned on external or internal dimension lines depending on an opening position in a part. The Axes and Contour options are taken into account for dimensions transverse with respect to the main element's axis.
Dimensions transverse with respect to the axis: these dimensions are placed on external or internal dimension lines depending on opening positions.
Dimensions on external dimension lines are generated for openings positioned on transverse edges of an assembly (in endplates). External dimension lines are positioned parallel to the direction specified for overall dimensions, and are always attached to the element's overall dimension.
Internal dimension lines are generated for openings positioned along the main element's axis. They are always placed perpendicularly to the main element's axis and as close as possible to dimensioned openings (in such a way so that they do not overlap with other elements in a drawing). Internal dimension lines are attached to the main element's axis or to one of external edges of the main part that is parallel to the axis (an edge positioned closer to a greater number of dimensioned openings is selected).
- Perpendicular openings -works the same as the Openings in view option, but if both options are selected, all points are projected onto a common dimension line.
- Angular - the following parameters can be specified:
- External - the dimensioning concerns external edges of the main part and of subparts placed outside the main part's contour, positioned unorthogonally with respect to the coordinate system of the main part. An acute angle is always shown, the base of which is a vertical line.
- Internal - the dimensioning concerns edges of subparts placed within the main part's contour, positioned unorthogonally with respect to the coordinate system of the main part. An acute angle is always shown, the base of which is an element's edge parallel to the axis of the main part.
- Both - dimensions are generated on the basis of both the internal and external options.
The options of arc dimensioning operate identically as in the case of single parts.
Define the Depth of a structure for which assemblies will be presented in drawings:
- Relative - with respect to a value of the 'depth' of a whole structure (100% - total depth)
- In absolute units - in current units
