2.1. - General Options
The selection of AutoCAD objects works in three different ways or Selection Modes:
• Select on screen: it will allow you to select individually or by picking those objects that you want to deal.
• Select by layers: that deal with all the objects appearing in the selected layers. In order to select a layer you must select any object contained in it.
• Entire Drawing: will add all the objects appearing in the drawing to the selection to be dealt.
You can also select the decimal places used to show or export the measures, being the range from 0 to 12 decimals.
There are checkboxes in most of the menus to perform filters of objects depending on the type of objects. That is to say, if we foresee that arcs are to be included in our selection but we do not want to add their length to the total sum, then we should only deactivate the box "Arch".
Insert Text. This option is available for tabs 'Length', 'Projected Length' and 'Area'. If checked, a text will be inserted near the object showing its property value. In tab 'Areas' a checkbox allows to insert a text showing the object perimeter. You can select a measure unit from 'Unit' list. From drop-down list Reference Point, user can choose the point of the object that will be used as insertion point of the property texts. Checking option 'Start Point', these texts will be inserted at the start point of lines, ellipses, etc; the first vertex of polylines, 3D-polylines, etc; and the center of circles. Checking option 'Center Box', text will be inserted at center of the circumscribed object box (Bounding Box).
2.2. - Total sum of length and perimeter
Working with entities:
• M-Line (computed length)
• 3D Face (computed perimeter)
TIP: Multiple lines and 3DFaces have not the property of length, but this can be calculated with the coordinates of their vertexes... as app does.
2.3. - Total sum of projected length (on plane XY)
Working with entities:
2.4.- Total sum of areas
Working with following entities:
• Hatches (only those that have area as property)
• Planar 3D-Face (those whose vertices lies in the same plane, coplanar)
Application calculate the area of a 3DFace if it is triangular (only three vertices are different, being one of the four repeated), as if it is a planar quadrilateral (four vertices are different). 3D triangular faces always have three coplanar vertices, but quadrilaterals not necessarily follow this rule. The program is not prepared to calculate the area of quadrilaterals whose points do not lie in a plane (skew quadrilaterals). However, the criterion for quadrilaterals is as follows: app calculates the volume of the tetrahedron formed by its four vertices and the area value of the parallelogram that they define: if the division is not greater than an internal constant number, then consider that the 4 vertices are coplanar and calculate the planar area under this supposition. That is, calculate the area whether the quadrilateral is flat as if it is approximately flat. The program works with any arbitrary quadrilateral: convex quadrilateral, concave quadrilateral and crossed quadrilaterals: it has no restrictions in this regard.
Some hatches, regions and SPLines may have not area as property. App will inform about this circumstance.
TIP: It doesn't matter if polylines are open or closed whenever we want to calculate their area. Not closed polylines have same area as it would have if an additional line joining their initial and final vertexes.
2.5. - Total and partial sum of length for user defined paths
It includes an option for exportation of values to Excel either for real distances or projected on XY plane
• Consecutive: with no gaps between points.
• No consecutive: there can be gaps between points.
Available options are:
Export values, to Excel of the coordinates of the selected points, the partial distance between them and the total one, either real or projected.
Insert index in AutoCAD, in a layer named "InnerSoft-Index". This layer will be completely cleaned before every performance of the application in order to avoid confusion between the indexes from different operations. The usefulness of the indexes lies in the ability of easily correlating the data exported to Excel and the objects of AutoCAD from which they come, apart from marking the points which have been used.
