ArchiCAD line type issue.

[Anonymous]

Hey Guys,

I've got a line type question here for ArchiCAD 9, perhaps someone can help me out? I am in the process of re-doing my firm's line types for showing rated walls (1-hr, 2-hr, etc). There is a line type in AutoCAD that we like and are trying to mimic. The problem is, ArchiCAD seems to be rounding out the line edges when I make the pen weight very heavy. The image below shows what I'm trying to do. Does anyone have any suggestions?

Thanks much!

Alan

I sympathise - Archicad tries to make pen lines look like Rapidograph lines, not Graphos lines.

Since you see that one fat line will blob up, make a new line type with your dashes at the interval you want and then multiply ten of them laterally very close together to broaden the stroke.

When drawn with a medium pen weight, it will stay square and look solid.

Thanks Dwight! That worked well. I created my new line type and it plotted great!

Thanks again!

For whatever it's worth, here is what I did with composite walls.

I made up some custom fills as shown in the image, used them for the fill in the composite wall dialog, and I get nice straight lines (fills) in the walls.

Hey! excellent tip Dwight I've been thinking about mimicking this line type for quite some time.

Dwight,

I assume you are meaning to multiply the single line in the drawing, which is a handy trick but a bit tedious. So you got me thinking...

What about applying the same trick to a symbol line type? I tried it and it works to a point. Lines have to be adjusted at corners to look their best, Polylines do their weird squeeze/taper at corners, but do a great job on tangential joins.

Not perfect but it approaches something people have been wishing for mightily for a long time.

That's how I interpreted Dwight's suggestion...and used it in a symbol line type. I agree with Matthew though that it would be a tedious job doing it purely as drawing lines....I would almost be tempted to do it as a fill offset to my liking using a very thin pen weight instead. I think the symbol line type method would be most preferred.

On reflection i can see how you might interpret what i said as suggesting separate lines, but i intended the ten lines to be assembled together in the symbolic line as you suggest.

What a difference a word makes, eh?

Great advice, guys. I've just recently been faced with this question from an architect that wants to duplicate the zip-tape or LetraSet LetraLine patterns in ArchiCAD. They come in very handy for fire rating, as well as demarcation of phases, match lines, mark-ups, and work limits.

We've been doing it with AutoCAD for years... Polylines can have width, which forms sharp, thick dashes. They can even taper between points, though I can't say I've ever used it that way.

I've used the wall-fill trick, but unfortunately, you can't use walls in details or on layout, which is where I need them.
