Can't snap to a specific block section ...
Hi everybody ...
I challenged this situation already a couple times and I have no idea why it isn't working - maybe somebody can tell me what I'm doing wrong ...
Here in this case ...
I have two blocks arranged in my drawing and I like to use primary the Info tool or alternative a Dim tool to get the measurement for a stair. But what ever I try - it looks like it is a "taboo" area and QCAD is hard working to get it done - but without success.
So, here is the little stair and I need to measure the vertical difference ...
... but I can't get the measurement without exploding the blocks.

Hey Husky
Try using snap to end points with the measurement tool, works for me

Nice - thank you Clive! Works for me too.Clive wrote:Hey Husky

Now I have a new Question ....
Why it doesn't work with the Auto Snap function?
I assume we found a bug ...

Looks like it Husky, you should report itHusky wrote:I assume we found a bug ...
Re: Can't snap to a specific block section ...
Looks like a performance issue.
Here's what happens in detail:
- As soon as you move the mouse cursor into the area of the intersection, QCAD starts looking for intersection points, end points, etc near to the mouse cursor.
- Since the drawing contains polylines with many thousands small segments, the search for an intersection takes very long (several seconds).
- Since QCAD does not immediately return a result, you likely move your mouse cursor in the hope that QCAD will still find the intersection.
- As soon as you move your mouse cursor, QCAD restarts the search since another intersection might now be the closest.
- As this continuous, it appears that QCAD never finds the intersection or end point.
Solutions:
- If the preview is very slow, you can simply click close to the intersection without waiting for a preview to appear. As soon as you click, QCAD searches for the closest snap point, without interrupting when you move the mouse.
- If you want to see a preview of the snap cursor, you would have to hold the mouse still in that place for a long time.
- Simplifying the polylines would of course also help.

I've looked into this a bit closer and was able to significantly improve the performance for this case (snapping to complex polylines in blocks) for the next release.

Hi Andrew
That's great, I'm sure Husky will be pleased too
