In the use of Baitu earthwork design software package (section CAD) process, when give a marked the location elevation, found "elevation Annotation" command provides a default value is wrong, why? How to solve?
Because "elevation system variable automatic maintenance section CAD" system to change the value of the reason.
The same cross section, the elevation of the values of system variables relatively unchanged; the different cross section, the elevation of the values of system variables are not equal.
To solve this problem there are two ways:
Way, if the current figure on a known point has marked elevation, or level, or ruler, the use of "elevation calibration" command: elevation, with the mouse in the graphic symbols corresponding to the water level or scale, or symbols symbol points to take, "section CAD" system Tip elevation calibration operation is successful, the the problem is solved. The process is to modify the elevation of Gao Cheng calibration system variables.
Method two, first to present a known specific elevation section on the value point elevation: the specific operation, modify the default values for the elevation of the actual elevation known point value. The default value of the modified elevation, elevation of the values of system variables is automatically modified. And then give the feature points of other unknown elevation in the section on the values marked elevation, this system provides default values are correct.
In the paintings of earthwork design software package (section CAD), how to set up the printing out the map scale?
The figure of earthwork design software package (section CAD) numerical unit agreed: in meters numerical input, the software automatically converts millimeter units, and in mm unit drawing.
Print out the map, select custom drawing ratio, the proportion of using map and the proportion of vertical section diagram corresponds, for example: if the vertical section diagram of the proportion of 1:100, with plot scale for "1 mm = 100 units" (on the left side of the drawing ratio in the text box to fill 1, right plot scale the text box to fill 100); if the ratio of vertical section diagram for 1:200, with plot scale for "1 mm = 200 units" (on the left side of the drawing ratio in the text box to fill 1, right plot scale text box to fill 200).
Box culvert structure internal force calculation of Baitu computational procedure, weight of side wall how applied?
Xiong Qijun "culvert" book examples are such processing: weight divided by the length of the side walls of the cross section of the base plate, converted into uniform load. The other method is to put the side wall of the dead weight and concentrated force treatment, little difference in the results of the two methods.
The calculation of internal force of box culvert is as elastic foundation beam frame structure calculation.
Not. The figure of box culvert procedure is based on the approach Xiong Qijun "culvert" compilation, the calculated results with the "culvert" on the examples are in good agreement with.
Whether to consider the open CAD does not automatically load plan program menu, only when the program will be loaded 100.
You can achieve this requirement. Operation method: enter the betu reinforced CAD, on the file menu, there are "Acad menu, click, the system switches to AutoCAD state, (but at this point the system has loaded the betu reinforced CAD) closed betu reinforced CAD, and then point to the desktop shortcut to the other, into their IT system, Basto reinforced CAD will not automatically load.
