Batt Insulation Question

[tennis4you]

I am having (2) issues with batt insultation.

 

1. When it is at a LTSCALE that looks perfect all other lines look awful.

2. I would like to have (2) different thicknesses of batt insulation in the same drawing, can I do that?

 

Thanks!

As well as the LTSCALE which is a global setting, you can set ltscale for individual lines in their properties which overwrites the global setting.

[tzframpton]

Adjust the object linetype scale itself instead of the global linetype scale parameter. Do this by selecting the line then via the Properties palette.

When working in metric I've found that setting the insulation objects LTSCALE to about the thickness of the desired insulation (so 100mm insulation would need an LTSCALE of 0.1) generally produces good results (this assumes PSLTSCALE=0).

 

I've never worked in imperial, but this might be a good starting value.

I put together a post on Linetype scaling that might help you understand what each variable is controlling.

However, you might consider using a hatch rather than a Linetype:

I second that! Until ADesk allows for a fixed value for object LTScale you can't get this type of thing to work in 2 different scales. E.g. say you've got a 1:50 plan and a 1:10 blow-up detail - you can adjust your LTSCALE variable and the object ltscale as you please but at best you'll get only one of those working correctly!

 

Another option is to search for some insulation / batting lisps ... there's quite a few!

Another way to go is to explode the linetype when it is at the correct scaling.

 

I adapted the ExpressTools explode text routine to explode linetypes. Very useful on the odd occasion

 

 

OOps, I just noted that the OP has LT.

LT can't use lisp

I use a Dynamic Block for batt insulation.

I use a lisp for batt insulation. I pick where I want it to start, where I want it to stop, and how wide and it pops it in there for me. No screwing around with linetypes and scales and all that. Three mouse picks and your done.

I know I've seen some be capable of doing curves as well, and making corners a bit neater than just normal batting linetypes. This is usually where the lisp type is better than the dynamic block, otherwise they're much of a muchness (even similar to use).

 

Where the DB batting beats the lisp is it's editable. If the lisp batting needs to change you have to re-do it. The DB is a simple click & drag.

[Jack_O'neill]

No, this one won't bend around a curve or corners. It's just start, stop and width in a straight line. All of these were drawn with the same routine. You can either enter coordinates with keyboard or mouse picks for start and stop, and enter or pick the distance for the width. It draws on whatever layer and linetype are current when you start the routine.

The entities are polylines too, btw.

The reason that I prefer a Hatch to a Lisp or DB is that it is much easier to edit. Just drag over everything and stretch (ok, If the hatch becomes un-associated, you may need to click it's grips).

 

One downside is getting the hatch scaled correctly in the first place - but once you've got the measure of this it is plain sailing.

 

Finally - hatches can't use curves, so using a hatch on a 1:10 scale detail is groovy but it would show up as being faceted on a 1:1 scale detail...

You could of course set the hatch to be annotative to get the scaling correct. But be warned, if you use a lot of annotative hatching (and you would with things like cavity walls) ACad tends to slow down like nobody's business.
