Custom Fill Pattern anyone?

31 Aug

Custom Fill Pattern anyone? – The Revit Clinic.

In AutoCAD, you can use the LSP file downloadable  to help you create a custom PAT file just by drawing what you want it to look like.  The LISP allows you to draw the pattern using basic AutoCAD elements, line, point, circle, arc, etc… in a 1 unit by 1 unit box.  Then the LISP translates what you draw in the box into a PAT file.  Now you can import the PAT file into Revit to create the custom fill pattern you need.

In Autocad:

1. open up a blank autocad drawing
2. set the snaps and grids to 0.01 units
3. draw a square 1 unit by 1 unit
4. draw your pattern snapping to the .01 unit grid with only normal lines. no circles, ellipses etc.
5. Your fill will repeat at the top and side ends so if it is a repeating pattern make sure it lines up
6. load in the attached lsp file by typing APPLOAD into the command prompt
7. browse to where the lsp file is located.
8. Click OK
9. Erase the square you drew
10. Type SAVEHATCH –> ENTER
11. follow the prompts

In Autocad, Create the pattern in real size, block it to scale as reference and resize it to 1×1 unit.

Run the Save hatch

select the entities,

Save the file as _Model with the second line ;%TYPE=MODEL

In Revit create the model

Use the Front Door

28 Aug

Revit OpEd: Use the Front Door.

There are usually at least a couple ways to start something or solve something in Revit, like life.

I’m frequently asked which “way” is the best or the correct “way”. It seems to me that Revit provides any number of “doors” to access information and tools.

Let’s take the notion of working with materials. I have a desk and I’d like it to have a specific material. These days I can select the desk, click Type Properties and, assuming the person who made the family provided a parameter to manage its material, I can click on the material value, which exposes the sneaky “Browse” button. This is a “side door” that lets me select and possibly alter material settings. If I don’t find a material I want I can make one while I’m here, click my way back out of the dialog and have a desk that looks great (hopefully).

In the past, if I didn’t like the material and there wasn’t one listed that sounded like one I wanted I’d have to bail out. Once out of the family’s Type Properties I’d open the material dialog and create it. Then I could go back to the desk and assign the material. They created the side door access so we could avoid that inefficient back and forth process.

I run into people that think the side door is the only way to create materials. That’s how they learned to do it and they keep doing it that way. The “front door” for materials is really on the Manage tab, the checkered globe button. This front door is the administrative task minded entrance while the side door is more the “spontaneous task” minded access point.

Another example is changing the number of a sheet. We can select the sheet view name, right click and rename. We can open the sheet view and select the title block family which in turn let’s us select and edit the sheet number. We can select the sheet number parameter in the properties palette too. Then again we can deal with it in a schedule instead. Keeping count? That’s four “doors”, a front, side, back, and “secret” door to accomplish the same task.

That might seem like too many options, which one should I use? Easy, which one is the closest to you? Where are you? In the back yard? I’d pick the back door then. Not in a sheet view and needing to renumber a bunch of sheets? I’d pick the “secret door” and use a schedule.
