Locking hatching to a starting point in an object
« on: September 18, 2018, 01:05:04 PM »
I'm a longtime user of DesignCad (1996 Work, 2000 Modeling)

I'm a model railroader with a laser and have been using hatching to put siding on walls and seams in floors. The hatching has always had a random starting point (I thought).

I just found that the starting point for the hatching is the zero on the ruler. That doesn't help when working on a building with four walls. It also doesn't work when I make a file to cut the parts on the laser. Zero on the ruler can't be the starting point for all the parts.

What I would like to be able to do is lock the starting point of the hatch I selected to a specific corner of an object. An example would be exterior walls with vertical siding. The material that I use is a scale 10 inches thick. If I set the hatching to produce vertical lines at a scale 10 inches the joint at the corner would appear to be the siding and not look like a joint.

I think what you are looking for is a command called 'Hatch Pattern Position'.
(It's the bottom of the list in the Edit menu)
You get to set 2 points - the first being a point on the hatch pattern you choose and the second being where on your drawing you want that to line up with.

It can be useful to centre tile patterns on floor plans etc...

Hatch Pattern Position (HPP) often forgets it's supposed to be on, though. After a few days or so you may notice the hatch went back to it's 0,0,0 origins.


The only solution I have for this is to make duplicates of the hatches (on other layers that will normally be off) and explode the originals after setting the custom origin. Exploding hatches turns them into line entities so I group them while they are still selected. The file size would obviously increase but in these days of inexpensive data that's not a huge issue. Plus it's better than sometime later opening the file, forgetting about the hatch issue, printing, and then re-discovering the issue.


Fyi: the reason I duplicate the hatches is because each could have different settings and if I ever want to make a small change to one I don't have to try to remember its settings. Another problem I find with hatches is that changing the Working Plane would reset all hatches to 0 angle. For this reason I don't use Working Planes (since my hatch angles are often not 0) but if I did then exploding would help here too. It would mess up the un-exploded duplicates, though.
