The second, conversion CAD block reference is executed.Including following sub-step:
1, program pin retrieves each file being dragged in file, when detecting dwg or dxf file type, first
Transformation Parameters are saved in file, then execute conversion (dxf need to save as dwg).
2, after reading Parameter File acquisition Transformation Parameters, graphic data base is read from backstage and generates graphic file.
3, graphic file All Layers are unlocked, locking layer is unlocked by traversal layer table record.
4, layout is found by traversal block table record, then the entity traversed in layout finds block reference, saves this block reference
Scale factor, recurrence blows block reference, until getting block each entity minimum bounding box referring in, finally obtains entire block
Reference minimum bounding box (herein why without using entity itself provide system function obtain minimum bounding box, be because
If to be obtained with system function, it would be possible to be unable to get correct minimum bounding box data, this point is by repeatedly practising inspection
It has been confirmed that).
5, whether met according to the relationship decision block reference whether minimum bounding box size and scale factor are greater than A4 size
Condition.If eligible, block is switched to current arrangements referring to place layout.Obtain it is all except the model space and current arrangements with
Outer all layout titles delete all useless layouts.Judge object space for model or drawing according to return parameters.If mesh
Mark space is paper space, traverses target paper space, obtains minimum area viewport, closes the viewport.
6, layer table is traversed, preservation is all to be turned off figure layer.
7, all entities being turned off in figure layer are obtained, they are wiped.
8, loop cleaning block defines, and all useless piece of definition is removed, until all useless piece of definition are fully erased.
9, traverse object space, search block reference, save object space block referring to ID, obtain all pieces referring to it is corresponding not
Repeatable block definition.
10, all not repeatable block definition are traversed, the block definition for wherein allowing to blow is searched, obtains wherein all pieces of references
ID is compared with correct block referring to the ID in set, if it is present this block can be used referring to ID.Save all pieces of references than
The example factor, recurrence blow block reference, all entities for including referring in until obtaining this block, find out the minimum of all entities and surround
Box finally finds out the minimum bounding box of block reference.Save the minimum bounding box data of all pieces of references.
11, all pieces of references are screened referring to minimum bounding box data acquisition system according to block, qualified piece is joined
According to electing, ineligible is filtered out.Finally according to from left to right, sequence from top to bottom is ranked up.Screening conditions:
It is not nested.By the block filtered out referring to progress x ascending order bubble sort.Result after sequence is returned.
12, it returns the result and then creates empty block file for sky, otherwise delete the Container elements for being less than A4 size.
13, the color of solid color figure layer where being changed to " with layer ".By traversal object space can blow
All pieces are blown referring to recurrence, decision block referring to comprising entity in whether there is attribute definition, if having block referring to retain, if
Block reference is not wiped then, and all entities of this additional block referring in are into object space.Object space is finally traversed, institute
Have solid color with the solid color of layer be changed to figure layer color.
14, whether merged by the interim setting Fileview file that VB interface creates, if dwf is generated, if do not conformed to
And CAD block is generated referring to filename file.By in each block referring to the text entity found within the scope of minimum bounding box
Or multline text entity, whether most on the lower judge its position, and meet coding rule (in addition to automatic control, can only comprising letter,
It crosses in digital, middle scribing line, at least two).If find qualified entity, content of text is saved as using later
Filename.If not finding qualified entity, current time is saved as filename.
15, invisible attribute definition is wiped.Object space is traversed, attribute definition entity is searched and is wiped if invisible
It removes.
16, window printing is carried out to block reference referring to minimum bounding box data acquisition system according to block.
CAD application object is obtained using ActiveX interface, according to whether generating dwf obtains printer configuration path.
Setting object space is current arrangements, obtains current arrangements, obtains printer setup object, setting printing config option (printing
Machine title, print area, printing origin, printing type, printing placed in the middle, whether in proportion printing, type style table, printed drawings
Width, printing unit).According to block referring to length and width size setting printing rotation mode.Traversal marker file is created, by printed drawings block number
File is written.If transverse direction, file is written into drawing serial number.If longitudinal direction, do nothing.
Setting printing map sheet.Practical drawing size is obtained referring to current length and width and scale factor according to block.Further according to reality
The customized map sheet mode of interim setting file user of the ratio and VB interface of size and A4 size creation, returns to customized drawing
Size dimension.If output is dwf file, automatically generates not duplicate file name and print, if output is pdf file, directly
Print to equipment.
Third, CAD block are referring to the processing after conversion.
Wherein, following processing is done for the file that output type is pdf:
1, the pdf page is rotated by traversal marker file.(being developed using Acrobat DC SDK)
2, it is renamed for the pdf file of output, keeps digital number therein consistent.
It is that a file (uses Acrobat DC by the pdf file mergences after renaming if 3, pdf finally merges
SDK exploitation), if nonjoinder, each pdf file is renamed referring to file by the block generated.
