We are experiencing plotting problems with Excel schedules linked to Autocad drawing files. When opened on one particular machine, drawings plot as intended. When opened on one other machine, plotting of the linked Excel schedules is erratic - sometimes some plot, usually none of the linked...
We have a pumping application where it was indicated that 460V, 100 HP pump motors would be supplied. NEMA size 4, reduced voltage (autotransformer) starters were installed. The supply voltage will be 480V. Upon arrival, the pump motor nameplate indicates 135 FLA at 460V. The starter...
I was recently asked a question about static dissipation for PVC piping. A small wordworking shop has fabricated their own dust collection system, using PVC piping. In operation, static is produced within the piping. What is an effective way to dissipate this static?
Does anyone have experience with upgrading the control system & drive motor for a motor operated drawbridge? We are investigating upgrades to an existing drawbridge that uses a 30 HP wound rotor motor and a resistor bank for speed control. Is anyone familiar with using an "off the...
Is there any way to lock, so to speak, specific drawing items / entities to prevent inadvertent changes? We have certain items on template drawings that I would like to be able to configure so that no changes could be made, either intentional or accidental. Any suggestions?
We have a drawing file with hundreds of of individual text items. These same text values are in one column of an Excel spreadsheet. Next to that column is another column of text that we would like appended to the Autocad text item. Would there be an automated method of editing the Autocad text...
Does anyone have a recommendation for fire detection required for elevator lobbies when elevator doors open to outside covered spaces?
This is a multi-unit, 3-story residential type building with elevators opening only to the outside. NFPA 72 Appendix A item A6.15.3.5 indicates that smoke...
I have a drawing file in which all devices, lines, etc. appear as the color black when in Layout. If switched to Model space, colors appear as intended. Anything added in in Layout also appears black. Any ideas on how to change the layout display to indicate colors?
I would like some input from engineers out there on how I should put together a price quote for an architect doing multi-unit residential buildings. We've been asked to provide a fee to design one building, but the Owner plans to build approximately 250 identical buildings over several years...
We have used small linked Excel spreadsheets for quite a while and been happy with the results. Recently, when plotting, various linked spreadsheets do not plot. The spreadsheet that doesn't plot appears under plot preview, it is just not plotted. It also seems odd that we can plot a sheet one...
I'm looking for a simple formula to calculate the depth required for concrete light pole bases. Known information will be: the mounting height of fixtures, EPA (effective projected area of fixtures), diameter of concrete pole base (example: 24"), wind speed (example: 100 mph), & gust factor...
