Generated ISO title block DXF: units, attributes and fonts when used in a template

[Margo App]

Hi, I'm building a generator that outputs ISO 5457 borders and ISO 7200 title blocks as DXF (R12 and R2000). I'm the author, and I'm here to ask rather than to promote.

 

Things I'd like your experience on:

 

1. Units: R12 has no INSUNITS, so how do you make sure a 420 x 297 sheet stays 420 x 297 in a .dwt?

2. Attributes: do you edit them in place or redefine the block?

3. Text style: any trouble with arial.ttf on machines with different fonts?

 

I can attach a sample DXF if that helps the discussion. Thanks.

"sheet stays 420 x 297 in a .dwt" not a problem various ways of doing this, simplest is have a layout "A3" which has your title sheet as only item in it. The title is at true size ie 420x297. And has say one viewport, just make a layout for each size. Where I worked that is how we did it, 20+ years using a DWT. Make sure add all your Text styles, layers, blocks and linetypes to your DWT, its easy to remove unwanted. Yes can add back in if needed.

 

Part 2 you can use Layout copy to make new layouts with the correct title block. The obvious is delete any sizes you don't want. Part 2a layout T you can use a template for the layout so it will read a layout by name from another dwg.

 

Ok maybe a big helper, there is code out there for making layouts automatically, as part of that the required title block can be chosen. A few choices pick a point in Model plus scale layout made, Use Rectangs as sheet outline and make multiple layouts in one go. Just ask for more detail various authors including myself.

 

As a new person at Cadtutor this may be of interest to you. Welcome aboard.
