In the hope that provides a wide range of CAD in the inquiry, the inquiry to make the best use of these CAD drawings designers draw a big convenience. CAD available in the hope of the project including the point coordinates (ID), the distance (Distance), size (area), quality characteristics (Massprop), time (Time) the query and other functions.

Coordinate inquiries

Look at the use of CAD in the process of drawing, and sometimes need to see the coordinates of a point, use the command ID can display the coordinates of the designated points. Enter the ID order, in the hope that CAD will show the designated point of X, Y and Z coordinates.

Distance query

Dist space command is used to calculate the distance between any two points and angle.

Dist query expressed by an order of meanings:

Distance: the distance between two points

XY plane angle: the connection between two points in the XY plane and the X-axis of the projection angle

XY plane and the angle: the connection between two points with the XY-plane angle

Delta X: No. 2 X coordinate relative to the first 1:00 of the incremental X coordinate

Delta Y: No. 2 Y coordinates relative to the first 1:00 of the incremental Y coordinate

Delta Z: No. 2 Z coordinates relative to the first 1:00 of the incremental coordinates Z

Area of inquiry

CAD in the hope that the area of inquiry in order to calculate a series of designated areas and between the perimeter, or the calculation of a variety of area and perimeter of the object. In addition, the order may also be used by additional models and model combinations to calculate the area.

Detailed command area of inquiry:

(1) call the "area" command, in accordance with specified prompted a series of corner, in the hope that CAD as a closed polygon of all vertex and calculate and report on the closure of the area and perimeter of polygons.

(2) call the "area" command, in accordance with an object prompt, in the CAD will look to calculate and report the object's area and perimeter; can be "area" command used including round, oval, spline curves, A number of lines, regular polygon, such as surface-domain and entity.

Using CAD in the hope of the inquiry

In two ways, through the above calculation may use the "Add (A)" mode and "minus (S)" combination mode.

(1) Add (A): This option is calculated using an area, the system in addition to the report of the area and perimeter calculation results, also add a total area of the area.

(2) minus (S): This option is calculated using an area, the system in addition to the area and circumference of the report's calculations, the total area is still in the area less.

Quality characteristics of query

Look at the CAD professional version also offers the quality characteristics of query command, you can calculate and show the surface quality of the domain properties or entities, such as area, centroid and boundary box and so on.

Using CAD in the hope of the inquiry

Point of CAD also allows users to order MASSPROP write query results to a text file, the results show that the final system will be given prompt:

"Into the document? Yes (Y) / <if (N)>":

If the user enters Y, the system further prompted to enter a file name, and the results stored in the document to. Mpr format export file, the file format can be opened with Notepad.

Table shows

Use the command list can be listed at the same time one or more characteristics of object's properties and geometric characteristics of the parameters.

Using CAD in the hope of the inquiry

Shows the status of inquiry

In fact, each state has its own graphics, the graphics state, including the limits, the use of model space, the current layer, color, line and other information, can be ordered by Status inquiries.

Time display time

The time the current drawings and other information for users to exchange CAD designers have been inspired by them. This information includes the current time, create time, last updated and so on, can be ordered query time.
