Dynamic Blocks

[#1]

A second place to show off. The first is getting long and slow to load and has been popular so I thought I would start another.
2007 format if you can. We are getting more Constrained DynBlk's posted that only work for a few SO please label what version created/saved in.
A contribution is attached. 2007 / 2007

Inetersting coffer there, Charles. You should see the tray ceiling effect I am trying to build in my old double-wide's dining room!

Anyway, is there a way to make the stretch actions rotate along with the coffer, so if they are applied after a rotate, they don't skew?

[#3]

You said in your previous post, in the old dyn blk show off thread, that you use excel with cad. How do you tie excel and acad together? Can you manipulate Dyn Blks?

[#4]

Well, yea; if you build it right and include the Width Parameter in the Rotate Action. Sheesh. Do I have to do everything!

I'm not quite that sophisticated to tie DynBlk to the spreadsheet.
The attached is a way to layout the stringer cuts so I can check headroom clearances and such. It's a pretty simple PLINE setup
Set the Spreadsheet parameters, Copy the column named Points up to the Total number of risers (If you have 15 risers copy the points up to 15 but not 15), PLINE command, Right click the command line and Paste. This will start at 0,0 since that is the first point.
The dropdowns can be revised to any common heights you have. These are just usual residential joist and ceilings heights.

It may not look like much but it was a pain in the butt to make!

Hey Reid that's right spiffy -- just takes a regen for the new distance to show up :-)

To Charles: snicker snicker

Btw, notice the spread of the use of "DynBlk"? It's working......

My thought on the clearances was I can add them to my stair block(s) by drawing a line from a set point above the top riser to the identical point above the bottom riser, and then add those ends to the stretch action for those risers. Since it's only for checking clearances, it could be on the defpoints layer. However, this could also be used to locate the top and bottom of a stringer and the top of a typical handrail -- I am thinking strictly as guides, but some smart person will take it further. The challenge is to do it without constraints and with as few visibility states as possible, yesno?

double visibility! I finally figured it out!!!


I better post a different block... Edited by: REID7800 on May 27, 2010 7:22 PM

Okay I am posting what I have so far, on a test stair with 11 risers, trying to do some of what I mentioned earlier. I figured out how to get something to stretch fractionally to the right, for example, when I pull the set of risers down in height, but there a few points such as the leading edge of the top of the riser, that need to move in two directions (or one direction at an angle) that, when I tried what I thought would work, the results were noticibly askew (so I removed those actions). The worst case in my current example has the top of the stringer off by about 3/16", but when I can get time I will try to plug away at it before I apply it to others. Unless anybody has some ideas....

Here we go. My double visibility block.

In the works is a double lookup, double visibility block. It works now I'm just trying to clean the block up a little. I hate actions flying everywhere in the block

Correction, 4 Lookup actions with 2 Lookup parameters. It was tricky to do Edited by: REID7800 on May 28, 2010 6:01 PM
