Cavity wall - precast concrete & masonry block

[nextvkin]

Hi,

I have a wall style which consists of a 150 concrete wall, an 80mm cavity, and a 150 masonry blockwall. However I want to show vertical joints (20mm gaps) in the concrete so as to look like precast concrete panels, the width of which will vary between 1800 & 3800mm. How do I go about doing that? Thanks in advance for any help

Pick line 1 pick line 2 use a lisp to draw the lines between, its pretty simple based around taking length of line repeating joints on a layer leveing remainder, tricky bit is putting some form of rule into corners. Others may have done this as aircondtioning ducting lsp.

 

Otherway draw 2 line joint use ARRAY, for lines on angle do UCS OB first then Array then UCS W

Hi Bigal,

Thanks for your reply, but I don't understand what you mean - I'm new to ACA. The other way sounds like plain AutoCAD doesn't it?

[BIGAL]

If you want to do smart wall patterning for precast slabs you must have rules, which end overlaps etc

 

Simply it sounds like at this point of your skill just draw two lines at correct panel length, you can use copy with ortho on drag in direction for next and type in spacing, once one is done you can use copy to multi copy with correct spacing , this invloves pick two lines base pt is start of line next point is the first line you drew, next point is first line of the brand new two line and so on hope this didn't confuse, movie some one please.

 

Or as I suggested if doing lots you may want a custon lisp pick pline all wall panels done in one go sorry dont have this code.

might have to use two separate wall styles, where the concrete part has the cleanup radius (forget its correct name!) set to zero, or less than 20mm anyway. the other wall would be continuous, but concrete panels are individual walls.

(i presume there is no rule to follow for length of panel - so you need to stretch end caps to suit design)

[BIGAL]

The easiest way is to write a wall panel lsp that replaces say a line and draws a true wall panel you take length of line divide by panel length a FIX of answer and you have x panels required plus a remainder.

 

Its probably a good task to have a go at writing a lisp plenty here will help. I have done this for wall panels including a Bill of materials for the panel maker but do not have the code any more.

I'll go for the 2separate wall option for now - thanks designerstuart.

Bigal, thanks for your suggestion but I don't know how to go about it, but will keep it for later research.
