    Startup PLANS Dwg with default views

    I am not too fluent in Arch Desktop 2002 2006 and am wondering if someone could share a DWG that can be used as the starting point for drawing a set of house plans. Ideally 3D model space would already have layers defined and layout viewports at the 36x24 planview boundarys would have tabs for...

    Showing Construction Details in drawing

    I create details that are drawn to scale (usually larger). Each detail is saved as its own .dwg I have another DETAILS.DWG which is simply a title block with 6 lines making a grid of 16 equal boxes. I load DETAILS.DWG and then xref into one of the 16 positions just the blocks needed for each...

    site plans

    In my local area (jurisdiction) the county accepts site plans for residential which are prepared by local draftspersons (non-registered). As an EOR for a project I am approached with a set of draftsperson plans which the owner wants to have structural detailing (stamping & calcs) for submittal...

    Step-motor accurate but physical movement not

    The chain has cogs on it that grip the wood. The 6' chain travels through about 2.5' of flat slotted track then loops around an 8" diameter toothed gear and always runs the same direction.

    Retaining Wall Spreadsheet

    I am about to write my own concrete retaining wall excel-spreadsheet. Does anyone have an un-protected (not for sale) sheet (or source) I could use as a starting point?

    Drawings in Excel

    You can use the built-in visual basic functions; Line, Polyline, Rectangle, Curve, etc. Here are some examples: Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range) Dim triArray(1 To 4, 1 To 2) As Single triArray(1, 1) = 25 'Assign values in code, Or triArray(1, 2) = 100...

    Step-motor accurate but physical movement not

    This looks great. I'll let you know what develops from my inquiry.

    Step-motor accurate but physical movement not

    Won't work. I am trying to monitor the position constantly as it moves. It may stop & start 30 times in 24'. The whole idea is to know where it is all the time so that the requested movement can be made.

    Step-motor accurate but physical movement not

    A saw pulsed-blade with teeth forced into the member and hope that the non-homogeneous material / sap don't vary the accuracy. I like the sound of that laser idea (no physical contact) better though. Anybody know if it's possible?

    Step-motor accurate but physical movement not

    I don't know what a "laser beam prox. switch" is. Can a beam be shot up to 24' at the lumber end and reflected back to a measuring device? It seems like the end cut of wood would be too variable a surface and, the 1/32" tolerance is still desireable.

    Step-motor accurate but physical movement not

    The machine & chain drive is heavy duty ($200,000), its just not accurate enough. The reel idea would work, but require manual labor to place the cable after each cut, and thereby slow the process still. The optical approach sounds interesting: Can you get 1/32" tolerance in 24' though?

    Step-motor accurate but physical movement not

    The slop is not repeatable, only consistently varying. Currently the operator halts production and manually adjusts out the tolerence with a tape measure: thereby establishing the need for better automation.

    Step-motor accurate but physical movement not

    The servo motor (very accurate) connects to cogged chains which grip the lumber. The slop in the chains, gears, & rollers yields errors in excess of 1/2" in 20' length. My thought is to more accurately measure the movement somehow and send the information to the servo's instructions. Remember...
