CADOverlayESP is to compare familiar scanning logo to edit software in last few years, because it is OK,mix vectorgraph and grating lattice picture the editor, vector of the Chinese character in the latticedot matrix graph that settles scanning gain thoroughly turns unfavorable issue, make it receives wide application. The experience that the author sums up in use process is below, here puts forward to consult in order to offer a reader. 1. In CADOverlayESP (ESP of the following abbreviation) , as a result of its interface and Autocad agree; Can at the same time overlay calls vectorgraph and grating lattice plan, reason is in call a respect to make mistake easily. Below the circumstance that in vectorgraph, lattice the graph coexists, if both file name is not same, answer to call vectorgraph first, call latticedot matrix plan again, the overlay that cannot implement two plans otherwise is called. 2. Because latticedot matrix graph is rotating, it is not as certain as vectorgraph to magnify the insertion that wait is nodded unified, reason had better make necessary adjustment to latticedot matrix graph above all, add vectorgraph on its again. The adjustment of need is: A) in command Image (advocate graph) with Irefmodify (modification reference pursues) lieutenant general its child command Density (density) the setting is agree with the density when scanning (it is 300dpi commonly) , because alter lattice,the density of the graph can affect the size that latticedot matrix pursues and proportion. B) to latticedot matrix the graph makes a standard at the beginning or perpendicular small angle is adjusted. 3. In ESP, what the whirl of 90 degrees of above that latticedot matrix pursues pursues with scanning forever is left next horn are a center, and the whirl of vector is factitious ground is given rotate center, in case already drew vectorgraph and need to rotate two overlay graph, need to rotate 2 center is unified, if do not know scanning lattice to pursue left,leave specific position of horn at this moment, usable Reditcrop commands cut is amended will decide. 4. In specific applying, often be the latticedot matrix figure that needs scanning already, the graph block diagram with need to insert original picture good again piece, and this is both one is with inch for the unit (former) , one is with centimeter for the unit, reason needs a lattice to the graph magnifies or narrow vectorgraph, the scale that its adjust is inch with centimeter conversion unit. After the attention is adjusted, answer to install scale to print a map according to particular case when printout. 5. The graphical file of scanning has a variety of patterns such as Rlc, Ig4, Tif, advocate although the graph can use a variety of forms, but referenced graph identifies Rlc pattern only, often need in real work advocate graph and referenced graph transfer into joining together is handled at the same time, can turn other format into Rlc format at this moment, ESP offerred this kind of format to change a file in order to offer. 6. Pursue to what already finished when printout, if need to rotate to pursue, the Coplot jussive Orientationofoutput that can output in plot - in Portrait/landscape (ask you place graph direction) , transverse or the input is fore-and-aft adjust angle. 7. The output that in ESP latticedot matrix pursues is printed is black and white from beginning to end, if need to emphasize some share with color, need to use chromatically of ability of vector line repaint, stuff. The Rtools that ESP can apply to offer when repaint and Vtools tool undertake. 8. The distinction of the tool Vtools that ESP offers and Rtools depends on: What its width and Autocad define the vector of Vtools is consistent, and Rtools is assorted line, its width can be defined according to needing to come (the latticedot matrix line in if need,pursueing with latticedot matrix is same width) . Rtools is assorted line, pitch on among them a paragraph small, criterion pitch on joins together with its, the whole line segment that draws together. And Vtools is apart line segment, pitch on is pitch on a paragraph among them only this paragraph of line segment. 9. In the job, need to amend several pieces of plans inside short time sometimes, notice a piece of graph is revised right now after ending, need to clear at the same time vectorgraph and grating lattice graph. If use Past command to call lattice of below one piece of grating to pursue directly, criterion part of the before one vectorgraph in Zhang Tu still is withheld go up in screen, cause a disorder with overlay of graph of the 2nd piece of lattice thereby.
