  1. Yes, just draw in some manual roof planes:
  2. Gene, this PDF is grayscale. Did you intend to post a file with blue?
  3. This is expected by now, isn't it? Most Chief "new features" seem to need more time in the oven.
  4. You can create a Pattern by manually drawing the dashes with individual CAD lines, the same as you have to do for CAD Blocks. ceilinggridhatch.calibz
  5. CA doesn't natively convert to ICF.
  6. When you export, uncheck Create Associative Dimensions:
  7. Google search "DXF to IFC". Lots of options pop up.
  8. The Replace button works for me.
  9. As others have mentioned, a 3D solid (nee: polyline solid) is probably the easiest method. If you must have framing members, they can be mitered at the ends by trimming them with other framing members:
  10. Here are what I use for normal stuff (for close-ups or critical renders I model the geometry of the deck, but that is a rare use case). pandeck.calibz
  11. You may want to consider a polishable overlay. Shayne makes excellent points, especially about the moisture content of the concrete. When I'm specifying a polished finish, this is my starting point: 033543 Polished Concrete Finishing General Includes ground and polished concrete floor slabs, including stained and polished concrete. Products Coordinate colorants, aggregates, and castings with the Owner. Concrete: Use normal weight concrete only, no air entrainment. Do not use volcanic aggregate for areas to receive an exposed aggregate finish. Admixtures may be used, except for calcium chloride accelerators. Densifier: Duraamen Hermetix Densifier, www.duraamen.com. Sealer: Duraamen Hermetix Protector, www.duraamen.com. Execution Comply with the General Requirements. Curing: Water curing is best to minimize edge and joint curling. Do not use topical curing agents that will act as a barrier to densifier penetration. Densification: Allow concrete to cure a minimum of 28 days before application of the densifier. Apply densifier ten days prior to installation of equipment and substantial completion to provide a complete, uninhibited concrete slab for application. Placement: Pour and work concrete to achieve a minimum Floor Flatness rating of 40 and minimum Floor Levelness rating of 40, where possible. Polishing: Perform the entire polishing process prior to erecting non-load bearing partition studs. Achieve the following finish: Coordinate the finish with the Owner: • Level 1 – matte finish (150 grit final polish). • Level 2 – satin finish (400 grit final polish). • Level 3 –medium sheen finish (800 grit final polish). • Level 4 – mirror finish (1800 grit final polish). • Class A – cream (no exposed aggregate) • Class B – salt and pepper (1/16” exposed sand, small aggregate). • Class C – medium aggregate (1/8”-1/4” exposed aggregate). • Class D – heavy aggregate (1/4”-1/2” exposed aggregate). Protection: Protect the concrete slab from damage both before and after polishing. All hydraulic powered equipment must be diapered to avoid staining of the concrete. No trade will park vehicles on the slab unless necessary; always use drop cloths beneath the vehicles. Do not stack or store construction materials or chemicals on the slab.
  12. Sure, depending on the situation. If you have a lot of steel on the job (steel-to-steel connections, column base plates, etc.) it's sometimes advantageous to stick with the same diameter bolt/stud groups throughout the project (based on feedback I've received from fabricators and erectors). In high-uplift situations, the limiting factor isn't the stud or nut, but the plate washer bearing area and the wood plate crushing resistance (compression perpendicular to grain). Three-quarter inch washers will give you nearly twice as much bearing for any given spacing. But, nothing to prevent you from specifying whatever diameter you need for your project.
  13. Except for unique or high-uplift conditions I use: arc stud groups (1) 3/4x2-1/2" low-carbon steel, standard-thread, full-thread arc stud (1) 3/4" A563 grade A hex nut (1) low-carbon steel square plate washer space studs along center-line of beam at 24" oc; joint to be finger tight; specified stud length is minimum post-weld length
