Description

How to edit the PDF format of drawings and save drawing documentation in the electronic system, especially in the field of construction

Field of technology

The subject of the invention is a method of editing the PDF format of drawings and storing drawing documentation in an electronic system, especially in the field of construction.

State of the art

At present, the 3D to 5D model is increasingly being promoted as a standard in the design and management of construction projects. It requires modifications to the PDF format of the drawings and storage of the drawing documentation, enabling its viewing and comparison, and subsequent use of the output from the browser, for example on a construction site or in animation. The PDF format remains the most widely available and widely used medium in electronic communication and archiving of various types of documentation. It does not require any special equipment, software or control knowledge and is therefore designed for the widest range of users.

Drawing documentation in PDF format is stored in closed files that contain individual documents. After opening the Folder (File), the PDF files will be displayed, which need to be opened for inspection, or rotated and zoomed in / out (Zoom) on the searched part of the drawing.

This is done with each document (drawing) separately, or it is possible to scroll and view the documents one by one after merging. For comparison, it is necessary to place two drawings next to each other and zoom in to the same place.

Opening after individual drawings, rotation and Zoom requires time and concentration. Not very suitable for viewing on small tablets and mobile phones - comparing side-by-side drawings requires more space.

The essence of the invention

The invention relates to a method for editing the PDF format of drawings and storing drawing documentation in an electronic system, in particular in the field of construction, where this system comprises a drawing viewer and a project archiving server and / or a mobile device connected to this server. The essence of the invention is that in an electronic system which contains at least one multifilament module with a PDF drawing file reader, an active starting point element of each drawing in a given format is added to the open format source file or directly to the PDF document format of this module. file always as a separate entity for active search of individual starting points, where drawings in PDF format are saved resp. combine into a single parent document in a module with a common denominator, where the starting point modulates as a separate layer the first hotspot for storing all drawings in PDF format, and where the next starting point of the module is as a separate layer the second hotspot to display the selected scale and direction indicators showing the correct rotation of the drawing, wherein all drawings, when fitted to the first active point, rotate and unify the scale according to the second active point, thereby placing exactly aligned on the same starting point, correctly rotated and in a uniform scale.

If there is a drawing section or detail in the multifunction module without the possibility of fitting a starting point directly on the drawing, the starting point is replaced by a reference point with reference to the starting point.

-1 CZ 308946 B6 point whose position is defined in X, Y, Z coordinates relative to the starting point and is placed, or the viewport is rotated, enlarged or reduced to the desired position in the overall view.

The electronic project division system preferably contains a second module with a browser, which as a database file is paired with all multifile modules within folders kept under one project number, with a reader function working simultaneously with multiple multifile modules, where the drawing browser includes a selection filter required search entities, where filtering criteria are created in the document code and co-create the drawing name.

The electronic system further comprises a third module for arranging the multifilament first modules according to the relative heights of the individual document elements, resp. PDF drawings, such as floors, floor and ceiling elements, or levels in an animated movie, to create a 3D layout of two-dimensional drawings in both horizontal and vertical layouts.

The third module preferably comprises another active point, which is the entry point of the construction as a reference point for defining by the user of the electronic system to the application with the third module on a mobile device, e.g. tablet or mobile phone, from which the actual selected distance on the construction is measured and its equivalent in scale to a multifilament first module in a 3D arrangement.

The subject of the invention is divided into a total of four modules: A + B, and independently C and D. Module A - PDF MultiFile Object (hereinafter the first MFO module) - is a PDF file reader with a new way (system) of editing drawings in PDF format by adding an active element (Insertion, Direction & Scale Point) - starting point.

The starting point is inserted either into the source file of open format (eg Dwg) or directly into PDF format, always as a separate layer (entity). The MFO reader actively searches for these points (levels) and adapts the individual documents accordingly.

PDF documents with an inserted active element are combined in the reader into one parent document - MFO.

The individual documents (drawings) are combined into one MFO, which are connected by a common denominator and the merging of which makes sense for the given task.

In the case of a construction project, these are, for example, all elements of ceilings / floors of a given floor.

In the case of an animated drawing, it is, for example, a moving figure or a background movement.

When opened, the MFO acts as a single document, stored in layers on top of each other. It allows you to "browse" the individual drawings that make up the MFO, and assign Opacity to one or all of the drawings in that MFO. Furthermore, it is possible to move the individual drawings in sequence.

All drawings in the reader are displayed at the selected magnification and show the same place (cutout) on all drawings in the file. Ie. it is not necessary to search for the required area in each drawing separately and it is possible to compare the examined place very quickly. After assigning clarity (Opacity), comparisons are possible without the need to scroll through the individual drawings. The name of the viewed drawing and the order of the individual drawings are displayed in the "scroll" line.

The solution of the electronic system according to the invention comprises a combination of two interconnected functions, which together provide the final desired effect: It is similar to layers in a PDF file with the difference that this is how

- 2 CZ 308946 B6 one MFO stores all documents (drawings) that are in the given file. Point A is a separate level. The second starting point B is the active element - a point showing the selected scale and a signpost showing the correct rotation of the drawing. After mounting on the first starting point A, all drawings rotate and unify the scale according to the second starting point B. Ie. all drawings in the parent MFO document will be stacked exactly at the end of the process, aligned by the same starting point, rotated correctly, and at a uniform scale. Point B is a separate level.

If there is a drawing section or detail in the MFO document without the possibility of fitting a second starting point B directly on the drawing, it is replaced by a reference point - a point with reference to the starting point. Its position is defined in Χ, Υ, Ζ coordinates relative to the Starting Point and places / rotates / enlarges (reduces) the viewport so that its position in the overall view is correct.

The present invention also relates to a method for classifying a project and the Browser itself (Module B Browser). The browser is a database file that is paired with all MFO documents within folders maintained under a single Project number. The browser works with MFO documents like the reader itself, with the difference that it works with multiple MFO documents at the same time. An essential part of the browser is the filter, in which the user selects the desired search entity. The filtering criteria are given in the document code (drawing) - eg Floor, Floor Element, Profession, Business File, Building Object, Revision, Date, etc. (Level, Level Element, Discipline, Trade Package, Building part, Revision, Date .. .). These criteria (codes) co-create the drawing number. The functions of the Browser are similar to those of the MFO Reader itself - scrolling, shifting the order, clarity and filtering according to the required criteria. Again, when scrolling, the same selected location and magnification is always displayed on each drawing in the window.

Modifications of this browser module serve as an Interface for authorized participants of the Project, or as a Project archive.

An additional element (for further use in modules for construction applications or in animation) is the active value of relative height in the drawing itself, or in the MFO code.

The subject of the invention is also the arrangement of MFO files according to the relative heights of the elements (module C) - eg floors (floor and ceiling elements) or levels in an animated film (Arranger). Creates a simple 3D layout of two-dimensional documents (drawings) in both horizontal and vertical layouts. By checking clarity and scrolling in these planes, it is possible to get the impression of movement in a three-dimensional changing environment, all in PDF format.

The functions of the 3D Arranger are similar to those of the MFO itself - scrolling, shifting the order, clarity and filtering according to the required criteria. Again, when scrolling, the same selected location and magnification is always displayed on each document (drawing) in the window (see Fig. 6).

The subject of the invention is furthermore the practical use of the above-mentioned module in the construction industry by means of a mobile device (tablet or mobile phone).

Another active point is added (module D) - Site Entry Point, which is the reference point defined by the user to the application containing the specified module on his mobile device to the MFO at the site entry point. It is usually a structure that does not change throughout the construction (eg reinforced concrete column or corner of the wall) and which is evident in the construction and in the drawing. From this point, the actual selected distance on the construction site (eg 1 m) is measured and its equivalent in scale is plotted in the PDF MFO 3D model.

This adjusts the scale of the 3D model to the actual scale of the building and the selected drawings are displayed in the floor and ceiling plane of the floor.

The position of the mobile device captures the actual position of the user on the construction site and, after switching on the camera in the application, displays in a double exposure the selected drawing in the model on the background of the actual construction - Fig. 6.

By selecting the degree of clarity and selection of the drawing, it is possible to check the compliance of the completed construction with the project documentation.

The inspection record (photo or video) with handwritten notes or commentary on the video is automatically saved in the construction inspection folder with the location on the drawing where the note was created.

Each new entry to the site (crossing the Site Entry Point) automatically creates a new folder with the recorded date and time, where all notes from a particular inspection are stored.

The source 3D model thus remains unchanged until a possible new update.

The essence of editing individual PDF documents is that an active element is inserted into an individual document (drawing) - Starting Point, which then unifies all documents (drawings) in the Reader according to the common origin, orientation and scale, thus creating a PDF MFO Document (Fig. 1, 2, 3).

The essence is also a method of grouping such modified individual PDF pages (drawings), where the resulting PDF MFO Document, containing a set of individual PDF pages (drawings) behaves as one page (drawing) with multiple layers - (Fig. 3). The essence is also the method of creating parent folders, forming a comprehensive Project, and viewing them from individual PDF MFO Documents in the Browser, where through the Filter are selected from all individual PDF MFO Documents in the main project folder to the Browser all individual PDF pages (drawings) with the required characteristics , given in the code (name) of the document (drawing).

The pages (drawings) filtered in this way again behave in the Browser as a separate PDF MFO Document, composed of these selected drawings - (Fig. 4).

Another object of the invention is a method of associating individual PDF pages (drawings) in PDF MFO Documents with active height dimensions. The overall Project, which contains a set of PDF MFO Documents, is reflected in the Viewer in a 3D layout - (Fig. 5). The subject of the invention is also a method of using the 3D arrangement in PDF MFO Documents in the Viewer, where this display in combination with the camera of a mobile device allows to see the drawing in double exposure at the desired place - (Fig. 6).

The subject of the invention is also the creation of a Site Entry Point in a mobile application and its alignment with the Documentation Starting Point, this connection aligns the documentation scale with the construction scale - (Fig. 6).
