 FAQ ANSWERS :::

 


IP-FQ-01 . How do I erase Column, Cut Beam Horizontal and Vertical marks in graphical editor?
Answer: These marks can be removed using the erase command from the 'Edit 'menu along with the Window option of the 'Select' menu. To remove these blocks first execute the erase command and then select window selection tool.A cross hair will then appear in the working window.Move the cross hair near the column mark and click the left button of the mouse.Now Hold down to execute the the left button of the mouse and crop a window column mark and leave the left button.The column mark will then be removed.

IP-FQ-02 . How do I view the greed numbers in the graphical editor of Build-Master?
Answer: To view the grid numbers in the plan execute the Show Numbers command from the 'View' menu. Now select the Gird Numbers option in the data dialog box and Click on 'OK'. The grid numbers will then be displayed on the screen.

IP-FQ-03 . How do I Increase the display size of various entities in the graphical editor of Build-Master?
Answer: This can be done using the Modify Sizes option of the 'Settings' menu. The Modify Sizes dialog box will then appear on the screen where in you can change pock box size,text size,support size etc.

IP-FQ-04 . How do I consider duct or openings in Slab?
Answer : There is a provision to delete any slab panel to create a Duct Opening. It can be created using following options :

 

Floor -> Edit Plan Data
Modify RCC -> Add/Delete Slabs

 

The Add/Delete Slabs dialog box will then appear on the screen. Select the appropriate row no. for the slab which is to be deleted and Click on Delete Row button to delete the slab. Thus a void will be created in the plan.

 

With this only the full slab panels can be deleted. Small openings in slabs without any beams around can not be considered. In such case hidden beams can be considered around opening and the internal slab panel can be deleted as above.

IP-FQ-05. Can I import a plan prepared in CAD to Build-Master?
Answer : A double line architectural drawing can not be read directly in Build-Master. Only single line plan drawn in CAD can be read directly. Each single line represents a beam in the plan. Double line architectural drawing can be opened in CAD in one layer and the beam lines can be drawn in another layer on the same plan using offset command. At the end only single lines shall be saved in the drawing.

IP-FQ-06 . How can I bring plan drawn in CAD to Build-Master?
Answer : Start new project using Build-Master. It will create a sub-folder in BMProjects folder. You can prepare the single line plan drawings in CAD. While saving the drawing, select the drawing type as .DXF instead of .DWG and file name as Project Code-Floor Code.DXF. For eg. if the project code is ABCD and floor code is PL (for plinth level) then the drawing prepared in CAD Package should be saved by the name ABCD-PL.DXF. Save this drawing in the above folder under BMProjects where project is started. By default CAD Package gives large USER LIMITS, therefore give LIMITS command in CAD Package and give realistic limits as -10,-10 to 50,50 mt. Draw the plan in mt. units. When you select the floor in Build-Master, the plan will be automatically visible.

IP-FQ-07 . What scales shall be used to draw a plan in CAD?
Answer : Single line plan shall be drawn with 1:1 scale with Mt units. A length of the line in CAD Package will be the length of the beam in Mt. By default CAD Package has a large value for user limit.This shall be changed with 'Limits' command to -10,-10 and 50,50.

IP-FQ-08 . Can I draw a curved beam in plan?
Answer : An arc or circle can not be drawn directly in input plan. However the curved beam can be idealized as a polygon with multiple lines. A polygon beam can have upto 15 parts.

IP-FQ-09 . Can a plan have a triangular or curved slab?
Answer : A slab can be triangular but cannot be exactly curved arc shape. However it can be represented as a polygon upto 15 sides.

IP-FQ-10 . How to change grid spacing?
Answer : A Separate option "Edit/Snap Grid Values" is available under "Settings" menu. Here user can make the grids on/off with "Show Grids" and select the option "Snap to Grid" to change the grid spacing and angle. The default value of grid spacing is 1 M.

IP-FQ-11 . While defining a new project, how many number of levels should be entered ?
Answer : For a Ground plus four storied building , number of levels shall be entered as Six. These levels are - lowest level as Plinth , then four Floor levels and topmost level as Roof.

IP-FQ-12 . How do I enter the data for a wall without a beam under it ?
Answer : For every wall you need to draw a beam line for entering wall data. If actual beam is not present, a fictitious hidden beam shall be assumed with Beam Depth equal to slab thickness and width equal to 300 mm and a beam line shall be drawn. But this will break the slab into two parts. If you do not wish to break the slab, the hidden beam shall not be entered. Then you can either increase the slab loading for the Partition wall or ignore the wall for the time being. There is a separate provision in the interactive slab design to add a wall line load. For details please refer to the answer of SD-FQ-03

IP-FQ-13 . How can I place a column in between the lines ?
Answer : A column shall be placed only at the end point of a line or at the intersection of lines. Hence, break the line at the desired point with BreakLine command in multiple equal parts or at an offset distance from the end point of a line.

IP-FQ-14 . How can I enter the Data for overhead water tanks?
Answer : The load on account of the water tank shall be entered as point loads on the columns and Beams supporting the water tank. For this Select Add Nodal Load option from the Draw menu of Input Plan. If a node is not present in the beam, at the Water Tank column location, then use Support --> Node option from Draw menu of Input Plan. According to IS:1893 (Part1)- 2002 (Refer to clause no. 7.12.2.1) , " The weight of any cantilever projection attached to buildings above the roof, (like Water tank, Tower, Parapets etc.) shall be added with the roof weight. A separate floor for Water Tank load need not be considered.

IP-FQ-15 . Do I need to enter separate Plans at each Level ?
Answer : The plan at that level shall be entered first, where the plan dimensions are maximum and all columns are present. This plan then shall be copied at the other levels and changes shall be made at these levels using Input Plan option. This way the Plans at all levels can be entered more efficiently.

IP-FQ-16 . How do I enter Data for a Project with Split-Levels ?
Answer : If a part of a Plan is absent at a particular level, or having double height, then delete such portion at that level where it is absent, and again enter it at the next level. When the Frame Analysis is done, and Frame is generated, the columns are generated with double height.

IP-FQ-17 . When two Beams inclined in Plan cross each other, how are they numbered ?
Answer : When two Beams inclined in Plan cross each other, By default Program will number them as Two Separate Beams. If one Beam is required to go full and other split into two at the intersection, use CutBeam Horizontally and CutBeam Vertically Marks to break the appropriately. It may happen that when MakeData command is executed, both the Beams get split into four separate parts. If one of the Beams is required to be numbered full, use Edit Plan Data option. Select Beam Nodes option from Modify RCC menu. Change Nodes of One of the Beams from 2 to 3 and make the Node of other Beam as End Node of first Beam. Now select Add/Delete Beam option from the same menu and delete the second Beam. This will change the Numbering in Desired way.
