No, it reverts back to the small window each time.

Neil and all, hi, 

I'm having the same issue, with a new computer on which I installed 
DC20.  And no, it doesn't.  Also the Layer Manager doesn't remember it 
is supposed to be on my second screen, and its size.  And the same is 
true for Object Viewer - small window every time.  I don't think I've 
used the Shader yet on this machine.  On my other computer, running the 
same version of DC20, I have none of these problems.  And yes, I have 
two licenses, I'm ambidextrous.  Is there a setting in Datacad.ini for 
this, maybe?

Where is DataCAD 20 installed?  Are you running it as Administrator? 

Is it installed in C:\DataCAD 20? 

I don't think a reinstall is going to fix this.  I would update to the 
latest version of DataCAD 20, and maybe ask on the DataCAD forum.  Dave 
G. may find a glitch, and fix it in the next update?

Debuggers,

I’m missing from DC 20 MS update KB4051034, do I need this update installed? 

I’m trying to resolve issues I’m having with DC 19 and DC 20, I am unable to use both because the Edit and Utility menus cease to function.  I have uninstalled and reinstalled both 19 and 20 which hasn’t resolved the problem.  I’m using DC 18 which does not have this problem.  I’m running Win 10.

TIA,

David Haynes AIA Architect

From the AWPA web site:

Can wood be preservative treated and fire retardant treated at the same time?
Under AWPA Standards, preservative treatment and fire retardant treatment are two different technologies.  Preservatives are expected to protect the wood from decay fungi and termites every day over a long period of time.  Fire retardants are expected to remain in the wood and protect it from a one-time event.  Some preservatives do impart a degree of fire retardancy, and some fire retardants can act as preservatives to some extent.  At this time, there is only one AWPA standardized product which may be used both as a fire retardant and wood preservative, and it is only listed for interior uses.  Apart from this, fire retardant treated wood should not be used where preservative treatment is required, nor should preservative treated wood be used when fire retardant treated wood is required.

Looks like there is one product that does a little of both. Sounds like it is part of a building envelope, so that would make it an interior use (as opposed to an outdoor trellis).

I suppose, as with any architectural challenge, one must UNDERSTAND THE PROBLEM before attempting to hurl solutions at it.

As those of us in the Peanut Gallery do not have any significant information, we will not be of any help.

Using fire-retardant treated lumber is a fairly rare thing. The ONLY times I've used it are when plywood or various blocking has been necessary in Type I and Type II non-combustible structures. Not needed in any other Construction Type, even in fire-rated construction, usually.

If you have water/moisture in your assembly to where preservative pressure treating is necessary, you've much bigger problems. Termites, of course, are a whole 'nother story. Preservatives are, at their core, poisons. Alas, the best poisons are behind us. I've applied barrels of the 'good stuff' back in the day. Yay.

I use truckloads of pressure-treated woods, both for fire and for preservative treatments. Always separate, however.

A couple of years ago, I had the onerous challenge of replacing a roof of aged 1x12 wooden planks. Can't do that in California. No longer legal, at all, with no means around it. What to do? Well, I pulled molds from rugged wooden planks of the size needed. Several different ones. Then sprayed custom-tinted concrete into each, followed by spraying layers of concrete with chopped glass fibers, adding fiberglass mat in the middle, more sprayed concrete with chopped fibers. 11,000 PSI mix. Result? Glass-fiber reinforced concrete planks that mimic the look of the boards that were their parents. Non-combustible. Fungus & termites won't go near it. Ought to last for a century or so, I figure.

Note that there are also pultruded fiberglass products that may be of use. SOME of those may be available with fire-retardant resins (you'd have to research that). While "studs" may not be available, channels and MANY other structural shapes are. We commonly use such in damp environments. Even underwater. Very easy to work with and assemble. This may prove a viable option for you. Great stuff! Here's one MFR:

Continuous rigid insul. on outside?


Hi Mark,

The problem with rigid foam, when we are using cement siding, is the weight of the siding "cantilevered" on the fasteners.  They can't be longer than about 3/4" out from the sheathing, but we need at least 2" of foam.  There is a fastener that can do this, but for corner conditions, this is awkward at best.

We are going to use a clip called ISO Clip, and steel angle furring, with rock wool insulation.  Then we can form both inside and outside corners, but avoid full depth framing (and the thermal breaks) and have the strength against sagging.  The fire resistant wood is to support the windows and PTAC grills, without a thermal break.

I would take a very cautious approach to using fire retardant treatments in framing exposed to summer heat.

The common treatments have a hugely negative effect on the strength of the wood fibers.

For 2" of rigid foam under fiber cement and 2x4s at 16" o.c., I used furring strips I ripped from 2xs. I used a router with a plywood template to make the grooves in the back of the foam. On another addition, I used 1 1/2 foam which has built-in grooves for furring strips. This was over 2x6 framing at 24" o.c.

Unfortunately, we need the thermal properties of wood, in this case.  We have to avoid full depth metal framing, to pas the new energy requirements.

Happily, stainless steel exists. In environments that are incessantly wet and where framing must be noncombustible, guess what we choose these days?

Here's a picture of the 1 1/2" foam with furring strips over 2x6 framing at 24" o.c. If you really need to 'hang' or 'cantilever' the fiber cement siding out 2", you might be able to use GRK cabinet screws. It might get a little pricey depending on how much area you need to cover, but I would imagine they are structurally sound enough to do the job.

DBUG> Select with Entity on and no snap selects area
From: jallen
Date: May 2 2018

My hard drive died and I'm trying to set up DataCAD as I had it.  One thing I can't find is where I set the select by Entity so that if there were nothing to snap to when selecting the left mouse button it would start a box to select by area.  I think it was in the .ini file maybe.  Can anyone here help me?

Thanks,

Jim Allen
